Maximizing Peak’s Performance

To get the best performance out of Peak and your Macintosh running OS 8.6–9.2, do the following.
To maximize Peak performance:
• Use a minimal number of System Extensions. Extensions can slow down your Macintosh by using precious processor cycles. In particular, turn off System Extensions such as menu bar clocks and screen savers that are in constant operation. To set up a dedicated set of extensions for Peak, duplicate your Mac OS Base extensions set in the extensions manager and rename it (something like Peak_set), restart your computer with this extensions set and install Peak, enable the additional extensions required for Peak to run, and, restart your computer with this updated extensions set.
• Set your monitor to no more than thousands of colors (256 colors is recommended for older Macintoshes).
• Disconnect your Macintosh from any networks and turn off AppleTalk, unless you need to be on a network.
• Use the Memory control panel to set the Macintosh’s disk cache to at least 384k (usually the Mac’s default setting is fine). Turn Virtual Memory Off.
• Allocate additional RAM to Peak if possible, using the Finder’s Get Info command. (Select Peak in the Finder, choose Get info from the Finder’s Special menu, and enter the desired amount in the Preferred Size field. Make sure you allocate more RAM than the amount indicated in the Minimum Size field!)
• Optimize your hard drive. (See Chapter 3 to learn about proper hard disk maintenance.)
Differences between Peak 3.0 on OS
8.6–9.2 and OS X.1
The carbonized version of Peak 3.0 will run on both Mac OS X.1 and older Mac OS 8.6–9.2. There are some differences in features because of the differences in capabilities of the newer operating system and the older operating system. These differences are described below.
VST
Peak 3.0 requires VST plug-ins to be carbonized if they are to be used with Peak 3.0 on OS X.1. Peak 3.0 can access both carbonized and non-carbonized VST plug­ins when used under OS 8.6–9.2. Contact your plug-in manufacturer for availability of carbonized versions of their plug-ins.

ASIO

Peak 3.0 allows you to use ASIO 1.0 drivers to record and playback audio when Peak 3.0 is used under OS
8.6–9.2. ASIO 1.0 technology is not compatible with
1
Introducing Peak
5
Page 18
the newer driver model in OS X.1, called CoreAudio.

CoreAudio

Peak 3.0 allows you to use CoreAudio for playback and recording when Peak 3.0 is used under OS X.1. Peak will play and record audio through the CoreAudio device selected in the CoreAudio dialog. CoreAudio has numerous advantages, including low latency, shared drivers across applications, and support for high bit-depths and sample rates.

Graphical User Interface

The Graphical User Interface (GUI) for Peak 3.0 looks slightly different when Peak 3.0 is used on OS X.1 v. OS 8.6–9.2. The OS X.1 GUI incorporates new OS X large application icons, and more of an aqua look and feel across the GUI. Examples include the transport button highlight colors, transport meters, and pin­striped theme backgrounds. Throughout this User’s Guide there will be graphics that display dialogs, windows, and menus from either OS X.1 or OS 8.6–
9.2.

Chapter 2: Installing and
Configuring Peak

Installing Peak

Peak’s auto-installer software makes installation very easy.
Your complete Peak system consists of:
• CD-ROM Installer
• Peak serial number and Product Authorization Code
(PAC)
Before you install Peak, please check the Minimum System Requirements on Page 4 of this Users Guide.
To install Peak:
1. If you are using any virus-protection software, turn it off or temporarily remove it, and restart your Macintosh.
2
7. At the end of the installation, the installer will allow you to register Peak electronically, which you may find more convenient than mailing your registration card.
8. When the installation is complete, a message will appear indicating that the installation was successful. Click Quit to quit the Installer, or click Continue to install copies additional copies (don't forget to turn back on any virus-protection software that you may be using the next time you restart the computer).
If want to run Peak on the same computer, but alternate between different operating systems (e.g., switching between OS X.1 and OS 9.2.2), separate copies of Peak will need to be installed and authorized on each OS. Peak will not operate under classic mode in OS X.1.

Authorization

2. Insert the Peak Install CD-ROM in your CD-ROM drive, open the Product Installers folder, and double-click the Install Peak icon.
3. When the Installer dialog appears, read the Read Me for late-breaking information concerning the Installer, then click Continue to proceed.
4. Select where you would like to install Peak, using the Switch Disk pop-up menu.
5. Click Install at the bottom right of this dialog.
6. After you have clicked Install, follow the on-screen instructions. Peak will be installed into a folder named Peak 3.0 on your selected hard disk.
Peak must be authorized to work on your Macintosh. To authorize Peak, you will need your Product Authorization Code (PAC) in addition to the serial number that appears on your Peak Owner’s Certificate. BIAS will provide you with your Product Authorization Code when you register Peak.
You must register Peak in order to obtain your Product Authorization Code; Peak will not launch after the 14 day registration period unless you authorize Peak with your Name, Organization, Serial Number, and Product Authorization Code!
Peak Basics
11
Page 24
When you first launch Peak, it will prompt you to authorize it by entering your Name, Organization, Serial number, and Product Authorization Code.
Using the Macintosh’s Built-In Inputs and Outputs
If you wish to use your Macintosh’s built-in audio inputs and outputs for recording and playback, do the following:
1. Turn down the volume on your playback system. Peak can be used with a variety of playback systems, including:
• headphones
Peak Authorization dialog
Send in Your Registration Card! After you have installed Peak, please send in the Registration Card included with your software to receive your Product Authorization Code, technical support, software updates, and notification of upgrades.
Peak will run, fully functional, in Registration Mode for 14 days. This allows you the time necessary to register you product and get the Product Authorization Code from BIAS.

Making Audio Connections

While it is possible to listen to Peak using a Macintosh’s built-in speaker or headphones, most people will prefer to listen through a better quality external speaker system.
It is very easy to set up audio connections between your Macintosh and a mixer or speaker system. Your exact setup will differ slightly depending on whether you are using the built-in sound input and output connectors on your Macintosh, or those of a third­party audio interface.
• a stereo receiver or amplifier and speakers
• a mixer, amplifier, and a pair of speakers
• a mixer and a pair of amplified (self-powered)
speakers
• or simply a pair of amplified (self-powered) speakers, smaller versions of which are often called “multimedia” speakers.
2. Connect your audio source output to the Macintosh's audio input connector. Your audio source can be one of a variety of devices, such as:
•a cassette or DAT deck output
•a mixer output
•a stereo receiver line output (such as “tape deck record” output)
•an instrument line output (such as the output of a synthesizer or guitar preamp)
The Mac’s audio input and output jacks are standard stereo mini-plug (1/8-inch) connector. Most mixer, receiver, and amplified speaker inputs are equipped with XLR, 1/4-inch, RCA, or mini-plug jacks. To make the proper connection, you may need to use an adapter.
Newer Macintoshes may not have a built-in sound input in which case you will have to use a third-party audio interface for sound input.
Peak User’s Guide12
Page 25
For advanced users: Certain professional mixing consoles, DAT decks, or other audio sources may have a nominal output level of +4 dBu, whereas the Macintosh expects to see a nominal –10 dBV level. Be aware that you may need to adjust your mixer’s output levels accordingly to prevent overloading the Macintosh’s input; or alternately, you may need to use a “+4 to –10” line-matching transformer.
3. Connect your Mac’s audio output to your playback system’s input.

Third-Party Audio Interfaces

If you have a Sound Manager-compatible, ASIO­compatible, or CoreAudio-compatible PCI, PCMCIA (CardBus), USB, or FireWire audio interface installed in your computer and wish to use its inputs and outputs, do the following:
1. Turn down the volume on your mixer or playback system.
2. Make sure that you have installed the third-party audio interface according to the manufacturer’s instructions.
3. Install the Sound Manager, ASIO, and CoreAudio drivers for your audio interface according to the manufacturer’s instructions.
4. Connect your source’s outputs to the inputs of your audio interface.
5. Connect the outputs of your audio interface to the inputs of your mixer or playback systems
6. Raise the volume on your mixer or playback system. Your system should now be properly configured and ready for recording and playback.
2
4. Connect your playback system’s output (typically an auxiliary or bus send) to your Mac’s audio input.
Be very careful to avoid feedback loops (the audio signal feeds back into itself) when recording. Feedback can damage both your equipment and your hearing.
5. Raise the volume on your mixer or playback system. Your system should now be properly configured and ready for recording and playback.
Peak Basics
A typical mixer/computer configuration is to have the computer outputs go to channel inputs on your mixer and to have the auxiliary or bus sends from the mixer go to the inputs of the computer. Instruments you want to record you patch into other channel inputs on the mixer and you can then route them out the
13
Page 26
auxiliary or bus sends on the mixer to be recorded by the computer. The mixer’s main outputs go to the amplifier/speakers.
To use a third-party audio interface for previewing audio (OS 8.6–9.2 only):
1. Choose Sound Out from the Sound Control Panel pop-up menu.
the interface in the ASIO Drivers folder, which is in the Peak folder, and launch Peak. For more detail on using Peak with ASIO-compatible audio interfaces, please read Chapter 4: Playback and Recording.

CoreAudio

2. Select your audio interface (Digigram’s VX Pocket is shown in this example) as the sound output device.
The Apple Sound Control Panel
3. Close the Sound window when you have finished.
The settings you make in the Sound Control Panel's Sound Output panel will only effect playback through the Import CD Audio dialog. For playback, you will need to select your audio interface in Peak's Sound Out menu.
Peak can use CoreAudio when running under OS X.1. If you want to use a CoreAudio-compatible third-party audio interface with Peak, install the CoreAudio driver for the interface in the Peak Plug-Ins folder, which in the Peak folder, and launch Peak. Be sure to consult the manufacturer’s instructions when installing your audio interface. For more detail on using Peak with a CoreAudio-compatible audio interface, please read Chapter 4: Playback and Recording.

USB and FireWire Audio Interfaces

Mac OS 9.0.4 or later supports USB Audio on iMacs, iBooks, B/W G3s, and G4s. Peak supports USB audio with interfaces such as the Tascam US-428. Peak also supports compatible FireWire audio interfaces, such as the MOTU-828.

Conclusion

Now that you have installed Peak, and installed and configured any third-party audio interface and its drivers, proceed to the next chapter to learn several basic concepts and functions essential to using Peak.

ASIO

Peak supports ASIO 1.0 when running under OS 8.6–
9.2. If you want to use an ASIO-compatible third-party audio interface with Peak, place the ASIO driver for

Introduction

This chapter explains several key Peak concepts and functions, including how to open, close, and save audio documents.

A Brief Explanation of Digital Audio

called digital sampling to convert analog electrical signals into numbers.
3
Digital sampling is the sonic equivalent of taking a snapshot. By taking thousands of little digital samples per second and storing them to a hard drive, an A/D converter can capture an accurate sample-by-sample representation of a sound, much like a movie is a frame-by-frame representation of a moving image. The number of samples taken of the audio in a second is called the sample rate.
If you are new to digital hard-disk-based recording, you may wish to acquaint yourself with a few of the principles behind digital audio before you dive into using Peak software. This section explains a few key concepts that will give you a good general under­standing of how Peak does what it does.
What we hear as sound is actually a pattern of pressure waves that move through the air. The frequency of these waves determines the pitch of the sound — how low or high it sounds. Sound frequency is measured in cycles per second, or Hertz (Hz). The range of human hearing is generally considered to be from about 20 Hz at the low end to 20 kHz at the high end. In practice, however, most adults hear only as high as 12 kHz to 18 kHz, especially those of us who may have spent more time than we should have with headphones or at loud rock concerts.
Sampling and Sample Rate
Your Peak software-equipped Macintosh computer stores audio digitally. This means that analog electrical signals from microphones or other sources are converted into numbers by a circuit called an analog­to-digital converter and stored on hard disk. The analog-to-digital (A/D) converter uses a technique
The sample rate determines the recording’s upper frequency response. A higher sample rate delivers higher frequency response. As a rule of thumb, a digital recording’s upper frequency response is roughly half of its sample rate (known as the Nyquist frequency). The audio on compact discs, for example, is recorded at 44,100 samples each second, or
44.1 kHz. This sample rate is the standard for professional-quality digital audio, and provides an upper-end frequency response of approximately half the sample rate (known as the Nyquist frequency):
22.5 kHz, somewhat higher than most people’s hearing range.
Bit Resolution
Another factor that affects the quality of the audio is the resolution of each sample. The greater the resolution, the better the quality. To use an analogy from the film world, just as image resolution and quality increase with film size (8 millimeter film is much lower in image quality than 70 millimeter film) greater bit resolution (8-bit, 16-bit, 24-bit, and 32-bit) results in better fidelity digital audio. Audio CDs have a resolution of 16-bits.
Peak Basics
17
Page 30
In practice, the bit resolution determines the recording’s dynamic range—that is, how many distinct steps you have to describe a sound’s level, from quiet to loud. For instance, an 8-bit recording has 256 (28) levels available, which is the equivalent of 48 decibels (dB) of dynamic range. On the other hand, a 16-bit recording has 65,536 (216) levels available, equivalent to 96 dB dynamic range. (The rule of thumb for determining the dynamic range in decibels is to take the bit rate and multiply it by 6.)

About Disk-Based Recording and Editing

If you are new to hard-disk-based recording, you will be impressed by the power and control that Peak software provides for recording and editing digital audio. You will encounter several new concepts and techniques for using a disk-based system such as Peak. Perhaps the most important among these is the concept of nondestructive manipulation of audio.
Nonlinear Versus Linear Recording
Nondestructive audio manipulation is possible thanks to the nature of Peak’s recording medium: a hard disk instead of a roll of analog tape. Unlike analog tape, which is a linear recording medium, hard disks provide a nonlinear, or random -access medium. This is because audio is stored on hard disk as digital information which the hard disk can access immedi­ately or randomly (hence the term “random-access”), simply by moving its read/write head to the appropri­ate location and reading the appropriate data. This allows you to perform such miraculous feats as cutting and pasting “pieces of sound” and rearranging material long after it has been recorded.
Nondestructive Editing
Perhaps most impressive is the fact that with disk­based audio production you need not actually modify the original source material in any way to accomplish these feats. In most cases, by cutting and pasting you
are in reality only asking the hard disk to access portions of the audio file in a slightly different order. Since Peak doesn’t normally cut up, move around, or delete the actual recording on the hard drive, it’s said to be a nondestructive editing system. Peak does not rewrite the file until you choose to save your edits.
Other manipulations, such as playing audio material backwards, can be accomplished by reading the data in reverse order. The power and flexibility of disk-based audio production software such as Peak far surpasses the capabilities of traditional analog audio production tools.
Hard Disk Storage Requirements
The actual recording of audio to hard disk requires a significant amount of storage. This is directly affected by the sample rate and bit resolution at which you record: the higher the fidelity, the greater the requirements for storage. As a guideline, 16-bit,
44.1 kHz audio requires roughly 5 megabytes of storage per minute of mono recording. Stereo 16-bit,
44.1 kHz audio requires roughly 10 megabytes per minute. Stereo 24-bit, 44.1 kHz audio requires roughly 15 megabytes per minute.
Hard Disk Maintenance
Because audio recording and playback is a hard disk­intensive task, it is important that your hard drive be in good operating condition. In the computer world, this means keeping it from becoming fragmented by using hard drive maintenance software. Fragmentation occurs as your hard drive begins to run out of contiguous (uninterrupted) space where it can write files. If the data that makes up a file is stored at a single location on your drive, it is much easier and faster for your drive to find the data and read it. However, as contiguous space runs out, the drive may not be able to write the entire file in one location and instead must fragment the file by writing pieces of it at various locations in whatever smaller open areas it can find. This requires that the drive search near and far to read the pieces of the file. Too much fragmentation can lead to errors in recording and playback as the
Peak User’s Guide18

hard drive struggles to keep up with the demands of your audio application.
In general, you should keep your hard disk below 10% fragmentation. Most hard drive maintenance software packages let you monitor the degree of fragmentation on your drive and defragment it by rewriting files into contiguous blocks of data. In addition to defragmenting your drive regularly, you should also back up your files and reformat your drive on a regular basis to keep your system in top operating condition. By doing this, you will ensure maximum performance from your Macintosh and Peak software and keep your studio running smoothly.
Now that you understand some of the basic principles behind digital audio and disk-based recording, take a few moments to learn some of the basic operations of Peak. These are covered in the sections that follow.

Creating a New Peak Document

Peak will allow you to create an empty audio file of zero duration by choosing a new mono or stereo document. However, you would typically record a new audio file in Peak or open an existing audio file into Peak for editing. Peak allows you to have multiple audio documents open at the same time.
To create a new audio document:
• Choose New (-N) from the File menu or Toolbar. This command provides a hierarchical menu which allows you to choose either a mono or stereo format for the new document.

Opening Existing Audio Documents

Peak allows you to open audio files created in a variety of common audio formats including AIFF, Sound Designer II, WAVE, QuickTime, Raw, System 7 Sound, Sonic AIFF, Paris, JAM Image, AU, and MP3.
3
Opening WAVE files
The Macintosh recognizes files using a “type” and “creator.” WAVE files are recognized by some audio
applications with a type “.WAV,” while others recognize only “WAVE” as the type.
Peak, along with Apple’s QuickTimesoftware and most other Multimedia applications, recognize WAVE files of the type “WAVE,” but not of type “.WAV.” You can use ResEdit or other third-party applications to ensure your WAVE files have the correct type prior to opening them with Peak.
Opening Compressed Audio Documents
AIFF/AIFC and QuickTime files with compression such as MACE 3:1, MACE 6:1, IMA 4:1, QDesign, or Alaw are compatible with Peak.
To open an audio file:
1. Choose Open (-O) from the File menu.
2. In the dialog that appears, locate the file that you wish to open. From this dialog, you can open AIFF, Sound Designer II, WAVE, QuickTime, Raw, System 7 Sound, Sonic AIFF, Paris, JAM Image, AU, and MP3 formatted audio files.
Creating a new Peak document

Page 32
Open dialog in OS X.1
3. When you find the file you wish to open, click the Open button and Peak will open the audio file into a new audio window, displaying an overview of the entire sound. Shift-click or -click to open multiple files.
recent documents
Recently Opened Documents
Peak automatically remembers up to the last eight audio documents that you have opened and keeps a list of these at the bottom of the File dialog. This allows you to easily select a document’s name and reopen it without having to search on your hard drive. Peak can find and open a document even if you have changed its location on your hard drive. If you change the name of the file, the next time you open Peak, it will automatically update the name in its internal list.
Recently opened documents in the File menu

Opening “Dual Mono” Files

Certain audio applications, such as BIAS Deck, do not directly support stereo interleaved files, and instead use “dual mono” files, which comprise the right and left channels of stereo material. Peak allows you to open such dual mono files, and in the process creates a new interleaved stereo audio document. Because Peak actually writes a new stereo audio file to disk, this conversion process requires hard disk space equiva­lent to the two original mono files.
Please note that the Import Dual Mono command requires that both files be mono files and have the same sample rate.
Peak User’s Guide20
Page 33
To open a dual mono file:
1. Choose Import Dual Mono from the File menu.
This feature is particularly useful when used with Peak’s Batch File Processor.
2. In the dialog that appears, locate the desired files.
3. Select either half of the dual mono file and click Open. Peak imports the first file and then prompts you for the second.
4. Select the second audio file and click Open. When Peak has finished creating the new stereo audio document you can begin editing.
For simpler importing of Dual Mono files, turn on the Auto Import Dual Mono feature in the Preference menu. With this feature activated, you can automatically import dual mono files by choosing Open from the File menu and selecting one of the dual mono file’s channels. Peak will then create a new stereo document containing both channels. Please note that these dual mono files must have exactly the same file name with the suffix “.L” for the left channel and “.R” for the right channel.
Peak also allows you to export your stereo audio documents in Dual Mono format, which means that it’s easy to import dual mono tracks from BIAS Deck into Peak, edit and process them within Peak, and then export them as Dual Mono files to be reincorpo­rated into your Deck sessions.

Dragging and Dropping Folders, Disks, and CD Audio Tracks

In addition to opening individual documents by dragging and dropping them onto the Peak application’s icon, you can drag and drop entire folders or disks onto the Peak application’s icon. The contents of the disk or folder(s) will be scanned for audio documents that Peak can open, such as AIFF, Sound Designer II, WAVE, QuickTime, MP3, and so on.
Peak allows you to drag a CD audio track directly onto the Peak icon or open the track directly from the Open command under the File menu or Toolbar. When you import a CD track using one of these two methods, the entire track will be imported. If you do not want to import an entire audio track, you can still use the Import CD track command under the File menu (covered in Chapter 4).

Saving and Closing Documents

It is good practice to save regularly throughout a project to avoid losing valuable work in the event of a power failure or other unfortunate occurrence. The Save command saves the changes you have made to your audio document by writing it to your hard disk. The Save command cannot be undone. If you want to be able to continue to undo your edits, use the Save a Copy As command under the file menu.
Peak allows you to save your audio documents in a variety of common audio file formats, each of which is described below. Be aware that different formats allow different information to be stored with the file. Peak preserves this information unless you save the file into a different file format. Saving a file in a format different from its original format may, however, cause some information stored in the file to be discarded.
Peak supports the following audio file formats:
• AIFF: This is Apple’s Audio Interchange File Format. It is also Peak’s default file format and is supported by many Macintosh software applica­tions.
• Sound Designer II: This is Digidesign’s audio file format for its digital audio products. Use this format if you wish to use an audio document in a Digidesign audio application.
3
Peak Basics
21
Page 34
• WAVE: This is Microsoft’s Windows Audio File Format. It is supported by many Windows software applications and some Macintosh applications. The WAVE format is best if you plan to use an audio document in an application that supports or requires WAVE format files.
•
QuickTime: This is Apple’s audio file format for
QuickTime-based multimedia. It is supported by all Macintosh software applications that support QuickTime. The QuickTime format is best if you plan to use an audio document in multimedia applications that support QuickTime, such as Macromedia Director™.
• Raw: This is the header-less raw file format that may be useful for some game platforms.

Using the Save As and Save A Copy As Commands

The Save As command allows you to save a copy of the current document under a different name, or in a different location on your hard disk. Since the Save As command closes the current document and lets you keep working on the renamed copy, it is useful for saving successive stages of a project. This allows you to save each major step under a different name. Later you can retrace your steps should you want to go back to an earlier version. The Save A Copy As command will save a copy of the file you are working on, but it will keep the copy you are working on open. This allows you to continue working on your audio and still be able to undo any edits you executed prior to using the Save A Copy As command.
• System 7 Sounds: This the Apple audio file format used for Macintosh Operating System Sounds.
• JAM image files: This is the JAM audio image file format. JAM audio image files may be created in Peak and used in Roxio JAM for burning audio CDs.
• Sonic AIFF: The file format used by Sonic Solutions audio workstations.
• .paf: This is the file format used by E-mu’s Paris audio system. Note this file format favors mono and dual mono files.
• .au: This file format is commonly used on the World Wide Web and in Java audio applets. It is supported by many platforms and programs.
• MP3: This saves your document in MP3 format.
To save a Peak document:
1. Choose Save from the File menu or press -S on your keyboard.
2. Select a file format from the pop-up File Type menu. AIFF is Peak’s default audio file format.
3. Enter a name for the new audio document, select where you want to save the new file, and then click Save.
To save an audio document under another name:
1. Choose Save As (Shift--S) or Save A Copy As (Option--S) from the File menu. The Save dialog appears:
The Save dialog
2. Select the desired file format from the File Type pop-up menu. AIFF is Peak’s default audio file format.
3. If you wish to save the audio document to a different bit depth resolution, click the bit depth pop-up. It is strongly recommended that you enable the pow-r™ dithering option if you are saving to a lower bit depth (e.g., 24-bit to 16-bit).
4. Enter a name for the new audio document, select where you want to save the new file, and click Save.
Peak User’s Guide22
Page 35
Using pow-r Dithering
If you are saving to a lower bit depth (e.g., 24-bit to 16-bit), it is strongly recommended that you enable the pow-r dithering option. Choose the pow-r Dither Settings from the Preference menu to adjust the settings for pow-r dither. For mono files, or stereo files with a narrow stereo field (e.g., recordings of solo instruments), use POW-r 1; for more stereophonically complex material, use POW-r 2; for full-spectrum audio with a wide stereo field, use POW-r 3.
The pow-r™ Dither Settings dialog
Saving Compressed Audio Documents
AIFF/AIFC and QuickTime files with compression such as MACE 3:1, MACE 6:1, IMA 4:1, QDesign, or Alaw are compatible with Peak.
You can only Save with file compression using AIFF or QuickTime file formats.
User Tip: Audio compression should be the last step in mastering your audio documents. Decompressing and re-compressing audio documents will degrade their sound quality each time they are re-compressed, so it is best not to save with compression until all editing and mastering has been completed.
To save an audio document with compression:
1. Choose Save As (Shift--S) from the File menu. The Save As dialog appears.
2. Choose the audio compressor you wish to use from the Compressor pop-up menu. Some compression formats only work with 8-bit or 16­bit data, so the compression options may be
grayed out, depending on your setting in the bit depth pop-up menu. Some of the types of available audio file compression include: MACE 3:1, MACE 6:1, QDesign Music, ALaw 2:1, 32-bit Floating Point, 64-bit Floating Point, IMA 4:1, 24-bit integer, 32-bit integer, 16-bit Little Endian, and 16­bit Big Endian.
3. Click the Options button to adjust the settings for the specified compression format, and then click OK.
4. Type the name of the new audio document, select the folder you wish to save the audio document, and click Save.
Closing Audio Documents
To close a file in Peak, choose Close from the File menu (-W). If you have made any changes to your document since the last time you saved, Peak will ask you if you want to save them. If you do, choose Yes; if you do not, choose No. If you change your mind and wish to continue your session, choose Cancel.
To close all files currently open in Peak, choose Close All from the File menu (-Option-W).

Peak Windows and Palettes

There are several windows and palettes when you open Peak that either appear by default or are available to you under Peak’s Windows menu. Windows that appear in Peak by default include an audio document window for each audio file you have open. Windows and palettes that you can turn on or off include the Transport, the Toolbar, the Cursor Palette, the Contents Palette, and the Movie Window. This section will cover the basic function of these Peak Windows and Palettes.

Peak Audio Document Window

Peak Audio Document windows contain a Waveform Display, an Audio File Info Bar and a Max Level

Transport Window

The Transport window is a floating, re-sizable window. It contains three areas: a time display showing elapsed time, the Transport controls (Return to Zero, Stop, Play, Go to End, Record, and Loop during playback), and audio level meters with clip/peak indicators.
Time Display
The Time Display is like a counter. It shows elapsed time and tracks the “playback head” as audio plays. Clicking on the waveform when playback is stopped will cause the current cursor location to appear in the Time Display. This display will also show the time remaining while performing Open, Save or DSP processing actions.
Meters
Peak’s meters are much like the VU or LED meters on a mixing board or tape recorder. They are bar graph meters that show the relative volume or loudness of the audio as it plays. They are also designed to show peak volume and whether the signal has “clipped,” or distorted.

Cursor Palette

Peak has a floating Cursor Palette that contains several useful functions. Along the top right side of the palette are four different icons representing different cursor modes. The default cursor is a standard Arrow Cursor. You can also use the cursor palette to select a Hand Cursor for moving a waveform within its window, a Pencil Tool for drawing directly on the waveform at the sample level, and a Magnifying Glass Tool for zooming the waveform view in and out. The ESC key on your computer keyboard will toggle through the four cursor modes. In the top left corner of the Cursor Palette there is a button that toggles Blending on and off. To access any of these cursors or functions, just click on the corresponding icon in the Cursor Palette. To change the cursor tool, click on a new icon. The Blending function is discussed in more detail in Chapter 5.
Magnifying Glass (“Zoom Tool”)
To use the Magnifying Glass tool, simply click on the tool in the Cursor Palette, then move the cursor over the waveform. A “plus” (+) sign will appear inside the Magnifying Glass. Click on the waveform to zoom in; each click of the mouse will zoom in farther. To zoom out, option-click on the waveform. A “minus” (-) sign will appear in the Magnifying Glass, and you can click on the waveform to zoom out. Double-clicking on the Magnifying Glass will open the Zoom Amount dialog where you can specify the Zoom Amount.

The bottom half of the Cursor palette displays the X (time) and Y (amplitude) coordinates of the cursor point, Sel: the duration of any currently selected audio), DTR (Distance to Reference Marker), and BPM: the tempo in beats per minute. You can type a value in for the X, Sel, and BPM parameters.
item in the Contents window will bring up the Edit Region or Edit Marker dialog.
Here is how to read the cursor and selection information that appears in the Cursor Location display.
Y = the current cursor position along the vertical
scale (amplitude) or start point of a selection
X = the current cursor position in the currently
specified time units (Samples, Min:Sec:ms, SMPTE, or Bars|Beats)
[L] = the cursor is currently positioned over the left
channel of the audio
[R] = the cursor is currently positioned over the
right channel of the audio
DTR = distance in the currently specified time units
(Samples, Min:Sec:ms, SMPTE, or Bars|Beats) to the nearest reference marker
Sel = the duration of the current selection in the
currently specified time units (Samples, Min:Sec:ms, SMPTE, or Bars|Beats)
+ or – = indicates positive or negative phase
BPM = beats per minute
The time format displayed in this field depends on which time format (Samples, Min:Sec:ms, SMPTE, or Bars|Beats) you have chosen with the Time Units command under the Preference menu.

Setting Preferences

You can customize a number of Peak’s parameters so you can work with the program in a way that best suits you. Most of these parameters are found in the Preference menu. These include the controls for playing back audio documents, the selection of the icons in the Toolbar, and the colors that you want for the audio document window. Once you have set these preferences as you like, they will stay that way until you decide to change them again. This section explains how to set several of these parameters. For any menu items not covered here, please refer to Chapter 11: Peak Menus. There you will find explana­tions of each command in the Preference menu and other Peak menus. Items from the Preference menu are also covered throughout this manual where their discussion is relevant.

Setting Peak’s Playback Parameters

Peak’s Playback Preferences dialog allows you to control the master output volume, hard disk playback buffer size, and window buffer size.
Peak Playback Preferences dialog
Playback Master Volume
Peak provides a master volume control for audio playback. In the Playback Preferences dialog, set Peak’s output volume to the level that you desire by adjusting the slider or entering a number value from 0 (silent) to 7 (loudest). If you are controlling your playback volume with the volume control of your playback system, you’ll probably want to leave the output level set to 7.
Playback Buffer
Peak allows you to control the amount of RAM the program uses when playing back audio documents. In general, lower is better. A playback buffer of 32k is a good place to start. If you are experiencing clicks in your playback, working with fragmented files, using processor-intensive real-time DSP, or are using a slow hard drive, you may need a larger playback buffer setting.
Window Buffer
Peak also allows you to control the amount of RAM the program uses to cache audio data and the size of each processing chunk. Use larger values if you are working with a few large files, and smaller values if you are working with many smaller files.
Dynamic Scrub Time
Peak provides a unique audio auditioning technique called dynamic scrubbing. This feature is very useful for precisely pinpointing and selecting a desired location in an audio document. Dynamic scrubbing allows you to drag the mouse forward or backward over a waveform while Peak plays a short loop (between 10 and 600 milliseconds) at the scrub location. When you have found the location you are looking for, let go of the mouse and the insertion point will be exactly where you want it to be. Peak allows you to choose the length of this playback loop with the Dynamic Scrub Time command in the Preference menu. You can also select Tape-Style Scrubbing in this dialog. For a full description of scrubbing audio in Peak, please see Chapter 5.
To select a loop duration for dynamic scrubbing:
1. Choose Dynamic Scrub Time from the Preference menu, and choose a duration from the hierarchical submenu. Typically, a value of between 40 to 80 milliseconds works well.
2. You can also select Tape-Style Scrubbing by selecting it in this submenu. To deselect Tape­Style Scrubbing, just click any duration value in the submenu.
Tape-Style Scrubbing requires Sound Manager
3.3 or later and is not available when using ASIO or CoreAudio.
Scroll During Playback
With the Scroll During Playback command enabled, Peak will “scroll” through the audio document as playback progresses. This allows you to visually follow the progress of audio playback. A check next to this menu item indicates that it is enabled.

1. Select Show Marker Times from the Preference menu. A check next to this item indicates it is enabled.
2. To disable Show Marker Times, simply deselect Show Marker Times from the Preference menu. The absence of a check next to this item indicates it is disabled.

Auditioning

Peak’s Auditioning command allows you to audition a selection along with a specific amount of audio preceding or following it. The Auditioning dialog allows you to select a desired amount of pre-roll or post-roll when you play the selection. To play a selection with the selected amount of pre- and post­roll, press Control-Spacebar.
To configure Auditioning:
• Select Auditioning from the Preference menu. Enter the desired amount of Pre-roll and Post-roll into the dialog boxes. Click OK to exit the dialog.
The Auditioning dialog

Blending

Blending is an automatic crossfade function with a user-editable envelope. Peak can apply blending to areas of an audio document when they are modified by cutting, deleting, or other editing processes in order to smooth abrupt transitions between waveform amplitudes. It can be very useful for creating a smooth transition between edits that would otherwise sound too abrupt. If you have cut, pasted, or inserted audio into a document, you may wish to enable blending to smooth things out a bit. It can be toggled on or off by choosing the Blending command from the Preference menu, or by clicking the Blend enable/disable button on the Cursor Palette, or by using the caps lock key on your keyboard.
Peak User’s Guide30

To configure blending:
1. Select Blending from the Preference menu. Enter the Duration over which you wish Blending to occur into the dialog box.
2. To edit the Blending Envelope, click on the Edit Blending Envelope button. Click OK to exit the dialog.
For detailed instructions on how to use blending or how to edit the blending crossfade envelope, see Chapter 5: Editing.
Auto-Import Dual Mono
Certain audio applications, such as BIAS Deck and Digidesign’s Pro Tools, do not directly support interleaved stereo files, and instead use “dual mono” files–a pair of files, one for the left channel and one for the right channel. These files have typically been exported with the suffix “.L” for the left channel, and the suffix “.R” for the right channel. Auto-Import Dual Mono, when selected, will allow you to select just one channel of the dual mono file in the Open dialog. Peak will automatically “grab” the other half of the file, and convert both files into a single stereo Peak document.
Please note that the Import Dual Mono command requires that both files be mono files, have the same sample rate and bit depth, and the must have the exact same name followed by the suffixes “.L” and “.R”.
To enable Auto-Import Dual Mono:
1. Select Auto-Import Dual Mono from the Prefer­ence menu. A check next to this item indicates it is enabled.

Choosing Colors for the Audio Document Window

Peak allows you to customize the colors used to display the elements in audio documents. You can use this dialog to set the background color, waveform color, and colors for markers and loops. You can select either a preset color combination, or individual colors for each element in the audio document window, as well as picking your own custom colors from a color palette. You can also choose to have the waveform display shading for a 3-D look, as well as select the amount of shading. Changes made using the Colors dialog affect both the current audio document’s colors, and any subsequent new audio document’s colors.
To customize the colors and shading of the waveform display:
1. Choose Colors from the Preference menu.
2. To select a preset color combination, click the Theme pop-up menu and choose the preset that you desire.
3. Alternatively, to select individual colors for each element in the audio document window, choose Custom from the Theme pop-up menu and then select the desired colors from the Background, Waveform, Markers, Loops, and Regions pop-up menus.
4. If you wish, you can use this dialog to further customize any element in the audio document window. Pick an element to customize, choose Custom from the Theme pop-up menu, and select User Color. A standard Macintosh color palette will appear. Use this wheel to select any color you wish. Click OK to return to the Colors dialog.

6. Another way to enhance the look of audio waveforms in Peak is by giving them a 3-D look. Use the Shadowed Waveform checkbox to turn the waveform shadow on or off.
7. To close this dialog, click Change (to change one color) or Change All (to change the colors for all open audio documents). The audio document window is now set to the colors and look you’ve selected.
Choosing a time format with the Units command
Audio File Meter, Tempo, and Timestamp Settings
If your audio document is using bars |beats as its units, you will want to tell Peak what the tempo of the audio document is. Use the Audio Info command from the Preference menu—or enter the BPM in the Cursor palette—to set the tempo of the audio document. You can also enter the meter of an audio document using the Audio Info dialog. The numerator represents the number of beats per measure, and the denominator represents the value of a beat, where 4=quarter note, 8=eight note, 16=sixteenth note, and so forth.
The Colors dialog
Choosing a Time Format
The Units command allows you to choose a time format for the audio timeline in Peak’s audio document window. You can choose samples, seconds, SMPTE frames, and Bars|Beats. The format you choose will depend on the nature of the project that you are working on.
To choose Peak’s time format:
1. Choose Time Units from the Preference menu.
2. From the submenu, choose the time format that you desire: samples, Min:Sec:ms, SMPTE frames, or Bars|Beats. The timeline in Peak’s audio document window and Transport switches to the format that you choose.

document with a time of 4 seconds instead of zero seconds.
Choosing a Scratch Disk
Because audio data can be very large, Peak utilizes a portion of your hard disk’s free space to hold audio data that has been cut or copied, as well as for temporary or scratch files for undo purposes. If your hard disk is short on space, you may not be able to cut, copy, or modify large selections. If you have more than one hard drive attached to your Macintosh, the Scratch Disks command in the Preference menu allows you to choose the hard drives (or “scratch disks”) that you wish to use for these temporary files. Peak allows you to select which disk you want to have as your default, or “Primary” disk for this purpose–usually you would select the disk that has the most free space. If you are connected to a file server, you can utilize available storage on the server by clicking the Allow Servers checkbox. Any available servers will then appear in the Scratch Disks pop-up menu. This feature is recommended only if you have access to a high speed Ethernet, Media Net, or other fast server.
To choose a scratch disk for temporary files:
1. Choose Scratch Disks from the Preference menu. The Scratch Disks dialog appears.
creates temporary files by clicking the checkboxes next to the drives in the list. To choose the Primary Disk, or the default disk for temporary files, click on the Primary button next to that disk. If you are connected to a file server and would like to use storage available there as well, enable the Allow Servers checkbox.
3. Click OK to close this dialog. Peak will use the disk you have selected as your Primary scratch disk, and, if it becomes full, will then use the other disks you’ve chosen.
The hard drive with the original audio file must have the equivalent amount of free space (i.e., a 60MB file would require that there be an additional 60MB of free space on the hard drive on which the file resides).
When running Peak under OS 9 or later (including OS X) you must have write permissions for the selected Scratch Folders and Disks or else Peak will report an error. Contact your System Administrator if you need assistance changing Directory or Disk permissions.
Keyboard Shortcuts
Peak allows you to customize any Peak menu item with a keyboard shortcut. To change your keyboard shortcuts, go to the Preference menu and select the Shortcuts and Toolbar item. Under OS 8.6 –9.2 the keyboard shortcuts are stored in a preference file in the System Folder’s Preferences folder, called Peak 3.0 Shortcuts; under OS X.1, this preference file is stored in Users/UserName/Library/Preference/. Peak’s default Keyboard Shortcuts are listed in Appendix 1 at the end of this manual.

The Toolbar

Peak allows you to select almost any Peak command for the Toolbar. The Shortcuts & Toolbar menu allows you to group together the functions you use most often, so that you can simply click a button instead of going to the menus. For example, if you frequently use Normalize and Pitch Change, you can choose to have the icons for these functions in the Toolbar, so that all you have to do to use one of them is to make an audio selection and click a button. The Toolbar is an easy way to make your work in Peak faster and more efficient, allowing you to customize the program to suit the way you work.
To add or subtract items from the Toolbar, use the Shortcuts & Toolbar item under the Preference menu. When running under OS 8.6–9.2, Toolbar selections are stored in a Preference file in the System Folder’s Preference Folder, called “Peak 3.0 Shortcuts.”

Chapter 4: Playback and Recording

In this chapter you’ll learn how to record and playback audio with Peak. Peak allows you to capture sound from external sources through your Macintosh’s built­in audio input or by using third-party audio hardware. If your Macintosh is equipped with a CD-ROM drive, you can also import audio directly from an audio CD. Peak will also let you record and playback via CoreAudio and ASIO.

Recording and Playback using the Apple Sound Manager

Peak will play and record through the Apple Sound Manager by default running under OS 8.6–9.2. Choose Built-In for Sound Out under the Audio menu and Peak will play through the Macintosh Built-In Sound. If you are using third-party audio hardware, its Sound Manager driver (if installed) will also appear in the Sound Out submenu.
The Sound Out submenu under the Audio menu running OS 8.6–9.2
Mac OS X Audio HAL is the Apple Sound Manager on OS X. If you are running Peak on OS X.1, select FireWire DV to use any supported Digital Video (DV) device—such as a camcorder—connected to a FireWire port, Mac OS X Audio HAL (System) to use the Macintosh Built-In Sound, or Mac OS X Audio HAL to use the audio device which is selected for output in the Sound System Preferences.
The Sound Out submenu under the Audio menu running OS X.1

Preparing Peak for Recording

Before you begin recording, you must set several parameters for the audio that you wish to record. If you followed the instructions in Chapter 2, your system’s basic recording and playback setup should already be configured properly. At this point, you may simply select Record Settings from the Audio menu or Toolbar to confirm or configure recording parameters, and then you can begin using Peak to record audio to your hard disk.

Proper Levels for Recording

To obtain the best possible fidelity when recording digital audio, it is important to record your audio signal at the highest possible level without introducing clipping (distortion). The reasons for this are twofold: If your audio input level is too low, the recorded audio may contain a significant amount of noise which can manifest itself as hiss. Conversely, if your audio input level is too high, it may clip and cause audible crackling or other types of distortion. You should avoid digital distortion at all costs because unlike its analog counterpart — which can sometimes sound “warm” and appealing — digital distortion sounds terrible. In order to prevent this from happening, always leave a little headroom (6 dB or so) when you set levels so that you don’t hit maximum input levels and clip.

Record Settings

available to your Macintosh unless you select otherwise.) Peak requires that you save the audio file to the same drive on which it was recorded.
When you select Record Settings from the Audio menu (Option-R) or Toolbar, the Record Settings dialog appears. This dialog is used to configure your settings for recording with Peak. The Record Settings dialog is basically the same for ASIO, Apple Sound Manager, or CoreAudio. However, the Device and Sample Format and Hardware Options buttons will open dialogs appropriate to the audio engine you are using with Peak.
Please note that the settings you choose here override any previously set with the Apple Sound Control Panel.
The Record Settings dialog
You will notice several pop-up menus, buttons, and checkboxes in the Record Settings dialog. These allow you to select which hard drive to record to, what file format you’d like to record in, sampling rate, source input, and so on. You may also wish to record through VST plug-ins. The next few paragraphs describe how to set all of these parameters using the Record Settings dialog.
Record Disk
The Record Disk pop-up menu allows you to choose which hard drive you would like to record to. If you have more than one hard drive connected to your Macintosh, use this pop-up to select your record drive. (This option will default to the largest drive currently
File Format
The File Format pop-up menu allows you to select the file format for the incoming audio. You can choose from AIFF or Sound Designer II. If you need the newly recorded audio file to be in a different format, you can always use the Save As function to save it as a another format once recording is complete. If you do not select a file format for recording, Peak will default to AIFF.
Auto Gain Control checkbox
The Auto Gain Control checkbox allows you to disable the Automatic Gain Control feature used by the Sound Manager with some Macintosh microphone inputs. If the recording device you are using supports this feature, check the Auto Gain Control checkbox.
Monitor checkbox
The Monitor checkbox allows you to monitor the audio throughput while you are recording.
Split Stereo Files checkbox
The Split Stereo Files checkbox allows you to record the incoming stereo audio as dual mono files rather than a single stereo file. Dual mono files are used in programs like Pro Tools, or BIAS Deck, so this option is useful if you need to record dual mono files (i.e., split stereo).
Append to document checkbox
The Append to document checkbox allows you to record into an existing audio document. To record new audio into an existing document, place the insertion point in the existing audio document at the point where you want to insert the new audio. If the insertion point is at the beginning of the file, the newly recorded audio will be inserted at the beginning of the file. If the insertion point is at the end of the file, the newly recorded audio will be appended to the end of
40 Peak User’s Guide
Page 53
the existing file. If the insertion point is somewhere in the middle of the file, the newly recorded audio will be inserted at that point. If you make a selection of audio, the Append to document feature will allow you to replace the current audio with newly recorded audio from the beginning of the selection through the end of the document or wherever you stop the recording.
Record timer checkbox
The Record timer checkbox allows you to designate a specific duration for recording. Peak will stop recording after this set time and then open the Save dialog for your audio recording. Checking the Record timer checkbox will bring up the Recording Time dialog. In the Recording Time dialog, designate the duration for recording in seconds and click OK.
right side of the dialog, a Speaker select pop-up, Volume and Gain controls, and an audio input level meter.

Hardware Options
Clicking on the Hardware Options button in the Record Settings dialog brings up a dialog appropriate to the audio hardware that you are using with your Macintosh. Note that in many instances there may be no settings for a given device (including the Apple Built-In Sound). Some audio hardware drivers have control panels or utility applications that will launch when you click on the Hardware Options button. The VX Control dialog for the Digigram VX Pocket is shown below, but the actual third-party dialog will differ depending on the specific audio hardware you have.
Your exact setup will differ slightly depending on the input device that you are using with Peak. You can use either your Macintosh’s built-in audio inputs, or, if you are using third­party audio hardware, you may wish to use its audio inputs and outputs.

Triggering Playback of Multiple Audio Documents

As explained earlier, Peak allows you to have multiple audio documents open at the same time. Peak assigns each of these documents a number based on the order in which it was opened. Peak provides you with a convenient way of triggering playback of any open audio document by pressing a number key on your computer keyboard. This can be a very useful feature for applications such as “live” sound effects playback, since you can open multiple audio documents and play them from your Macintosh keyboard.
To trigger sequential playback of multiple audio documents:
1. Open several audio documents, taking note of the number that Peak assigns them in the Windows menu. (This is based on the order in which the documents were opened.)

The Record Dialog

When you select Record from the Audio menu (-R) or Toolbar, the Record dialog appears. There are transport buttons along the bottom to Start, Pause and Stop the recording, an Audio Source display that shows you the waveform as it is being recorded, and a Notepad window. There are also text displays showing you the sample rate, bit depth, and number of channels you selected in the Record Settings dialog, as well as the amount of time you have left to record on the selected Record Disk.
2. Press the number which corresponds to the document(s) you wish to play. (Note: the numeric keypad will not work for this function, you must use the numbers at the top of the keyboard). You don’t need to wait until a document has finished playing to press the next number: typing a numerical sequence on your keyboard will “cue up” all of the corresponding files. They will then play in the order you choose.
3. If you wish to stop playback and jump to the next document in line, press the Return key. Peak initiates playback of the next document in sequence.
48 Peak User’s Guide
The Record dialog
The Notepad feature in the Record dialog allows you to type in text descriptions, transcribe a recording, or type in comments called Notepad Cues at specific points during the recording of an audio document. The Notepad feature is available from the Record dialog and may be used once a recording starts.
If you enable the Notepad checkbox, you can create markers while recording. Each time you press the Return key, a new Notepad Cue (marker) is generated for the current recording time. You may then begin
Page 61
typing text to describe the audio recording at that time (i.e., naming the marker). When you hear the next significant event in the recording, press the Return key to create another cue, and so forth.
When you are finished recording, Peak will create markers in the audio document that correspond to each Notepad Cue you have entered. If you also enable the Notepad regions, not markers checkbox, Peak will create regions during recording.
Notepad Cues are not available in Peak LE.
6. Adjust the output of your audio source so that its signal registers relatively high on the meters but never hits top (indicated by the red Clip Indica­tors.). Remember to always leave 6 dB or so of headroom on the meters so that you don’t clip. Use the yellow and orange meter lights and red Clip indicators to help you make this adjustment.
7. Click the Record button in the Record dialog. You are now recording to disk. You should see the audio waveform begin to scroll in the Audio Source Display window.

Importing a Track From an Audio CD (CD Audio Extraction)

If you own a Macintosh computer that is equipped with a compatible CD-ROM drive and Apple’s Sound Manager software (version 3.3 or later), you can use Peak to import audio directly from an audio CD. This process is sometimes referred to among multimedia developers as audio extraction, or audio-across-SCSI. If you own an Apple or non-Apple external CD-ROM drive, you may also be able to take advantage of this feature.
Please note that not every CD-ROM drive supports audio extraction, and that even among drives of the same model, one drive’s firmware (the internal operating software) may support audio extraction, while another’s may not. If you are unsure as to whether or not your drive supports Apple-standard audio extraction, your best bet is to try the instruc­tions that follow. If this doesn’t work, please contact the CD-ROM drive’s manufacturer to establish whether your drive (and your drive’s firmware) will support Apple-standard audio extraction.
To import tracks from an audio CD:
1. Insert an audio CD in your CD-ROM drive.
Import CD Audio dialog
4. To name a selected CD track, click the Track Name button. If have iTunes installed and are connected to the internet, Peak will recognize the track names by their ISRC codes as they are registered on the CDDB™ online CD database.
5. To select only a portion of the track, click on Set Import Times button or double-click on the track in the list. The Audio CD Import Options dialog will appear.
2. Choose Import CD Track from the File menu or click the CD button in the Toolbar.
3. In the dialog that appears, select the CD track that you wish to import and click Mark. You may mark multiple tracks for import. If you wish to import all of the tracks on the CD, click on the Mark All button.

Chapter 5: Editing

This chapter introduces you to the concept of digital audio editing. You will learn how to do digital audio editing with Peak’s many powerful digital editing tools.

Editing Audio with Peak

Peak provides you with a powerful interactive, nondestructive environment for editing and manipu­lating audio. In this environment, not only are virtually all editing actions completely “undo-able” and “redo­able,” but they can be performed interactively while audio playback is engaged.
Interactive Editing
Interactive editing means that you can cut, paste, loop, and process audio with DSP functions and Plug-Ins even while playing back the very audio that you are editing. For example, you can start playback, cut a selection of audio and paste or insert it later in the document, and when Peak reaches the location of the inserted audio, it will play it as if it were there all along. This revolutionary capability makes Peak a supremely fast and flexible audio production tool that makes conventional recording and editing methods, such as analog tape and a razor blade or Sound Designer, seem primitive and archaic by comparison.
Nondestructive Editing
Peak’s nondestructive editing capabilities mean that the edits you perform to an audio document do not permanently change the original source recording until you finally save the document. Thus, you can cut, copy, paste, fade in and out of, and otherwise completely change a recording, and still be able to return back to square one — the original untouched
state of the recording — up until the time that you save the document to disk. At that time, all edits are permanently written into the document.
Unlimited Undo and Redo
As an editing session progresses, Peak maintains an internal list of the edits that you perform. Changes that you make to an audio document are not permanently applied to the file until you ultimately save it. This is what gives Peak its unprecedented unlimited undo and redo capability. Through the use of the Macintosh’s standard Undo and Redo commands, you can undo or redo your actions sequentially, or by using the Edits command, using a “playlist-style” editing event list. This is a very exciting technology that allows you to maintain complete creative freedom of choice—right up until the last moment before you save your project to disk.

The Audio Document Window

The heart of Peak’s powerful editing capabilities is the audio document window. The audio document window provides you with a “window into sound,” allowing you to make good use of both your eyes and ears to perform extremely precise editing tasks. The Audio Document window gives you a time-domain representation of sound, that is, you see the amplitude of the sound over time.

An audio waveform

An Audio Waveform
If you have never seen sound displayed in a visual format before, it may not be immediately obvious how to “read” an audio waveform. It is actually quite easy to navigate through a recording with a waveform as your road map. The peaks in the waveform are areas of high amplitude (loud spots). The valleys in the waveform are areas of low amplitude (quiet spots). If the audio material is music with a pronounced, regular beat, it is generally very easy to pick out where the beats are simply by looking for peaks. Using this information, and the guidelines given shortly in the “A Selection” section, you will be able to successfully locate and select a desired portion of the audio document and perform the edits that you wish. The cursor marks the current location, and also serves as an insertion point.
Audio Waveform Overview
Peak provides an Overview display of the entire audio waveform along the top of the screen under the menu bar. This provides you with a convenient visual reference of the overall document when you are editing only a portion in the audio document window. The highlighted area in the Overview display shows the area of the audio waveform currently visible in the audio document window. If desired, you can hide the Overview display to allow the audio document window to occupy more of the computer screen.
To show the Audio Waveform Overview:
• The Overview display appears along the top of the audio document window under the title bar. Check Show Overview in the Preference menu or Toolbar. A check next to this item indicates it is enabled.
To hide the Audio Waveform Overview:
• To hide the Audio Waveform Overview, uncheck Show Overview in the Preference menu or Toolbar.
Vertical Scaling
Peak allows you to control the vertical magnification of audio waveforms. This feature is useful if you are editing and viewing a document with very quiet audio material.
To increase the vertical scaling magnification:
• Hold the Control key down and press the Up Arrow key.
To decrease the vertical scaling magnification:
• Hold the Control key down and press the Down Arrow key.
Peak User’s Guide56
A waveform with selected audio

A Selection

A selection is just what it sounds like: a portion of audio that you have selected by clicking and dragging with the mouse. You must select audio in order to perform an editing action on it. To make good selections for editing, the best rule of thumb is to begin a selection just before a peak in the waveform and end it just after a peak in the waveform. In other
Page 69
words, try to make selections start and end in areas of low amplitude (“valleys” in the waveform).
It is also important, when possible, to begin and end a selection at a point where the waveform meets the zero crossing line (the center line through the waveform). This helps you avoid creating pops and clicks if you later cut or paste the audio because the point at which the waveform meets the zero crossing is a point of no amplitude in the sound wave. Pops and click generally only occur if you make a careless selection and begin or end on a portion of the sound wave where the amplitude is high (where the waveform is high above the center point). Enable Auto-Snap to Zero in the Preferences menu to have Peak nudge your selection to the nearest zero crossings automatically.
The Zoom In function helps you make very precise selections by letting you zoom in to a higher magnifi­cation and select exactly the portion of the waveform you desire. Also, once you have made a selection, you can adjust the beginning or the end of the current selection by holding down the Shift key and clicking with the mouse. Your selection will be shortened or lengthened accordingly.
A waveform with a Marker (named “Verse2”)

A Marker

A marker can be placed in a document to identify a point of importance. A marker appears as a line with a solid triangular base. Peak allows you to place markers into a document in order to mark a given location or region in a document for later selection, navigation, or editing. Markers can be moved, named and renamed, “anchored” to a particular location on a waveform, and given other attributes. The use of markers is covered in greater detail later in this chapter.
5
Channel Independent Processing
To select only the Left channel, move the cursor over it. The cursor will show a small “L” at the insertion point. To select only the Right channel, move the cursor over it. The cursor will show a small “R” at the insertion point. You can process one channel of an audio document using Peak’s native DSP or third-party plug-ins.
Peak allows you to select and process the left and right channels of a stereo file indepen­dently, but you cannot edit (i.e., Cut, Paste, Delete, etc.) the left and right channels of a stereo file independently.
A waveform with loop markers

A Loop

A loop refers to a section of audio that is bounded on either side by loop markers. In the illustration above, the area that falls between the loop markers “beg loop” and “end loop” is looped. Loops are used to sustain or repeat a section of audio. They can be used for material that you intend to transfer to a sampler, or simply for playback within Peak itself. Peak allows you to create one loop per audio file.
Editing

Page 70
A waveform with 2 adjacent markers (named “Break #1 and Break #2)

Audio Between Adjacent Markers

Audio between adjacent markers refers to a section of audio that is bounded by markers. In the illustration above, the area that falls between the Break #1 and Break #2 markers is audio between markers. (Note: A selection of audio between markers is different than an audio Region. Regions are described later in this chapter, as well as in Chapter 6, Playlists and Audio CD Burning.)

Audio Info Area

In the lower left corner of each Peak Audio Document is the Audio Info Area. The Info Area shows the maximum amplitude, sample rate, bit resolution, file format, and file size of the audio file.
Audio Info Area
Clicking on the Max dB section of the Audio Info Area will open the Change Gain dialog, so that you can change the gain for the entire audio file, or the current selection. For more information on the Change Gain DSP function, please refer to Chapter 7, DSP. Clicking on any other portion of the Audio Info Area will open the Audio Info dialog.

Audio Info dialog

Selecting Audio Info from the Preference menu ( -I), will open the Audio Info dialog. The Audio Info dialog allows you to change the sample rate, duration, root key (for use in a sample playback instrument), and high and low key range. Note that by changing the sample rate, the pitch and duration of the audio will be affected. (To change the sample rate of an audio
document without changing the pitch, use the Sample Rate Conversion command from the DSP menu, or click on the appropriate Toolbar icon.) The Audio Info dialog is described in more detail later in this chapter, as well as in Chapter 11: Menus.
Audio Info dialog

Selecting Audio

In order to perform any type of editing action on an audio document, first you must select the portion of the document that you wish to modify. Peak has several techniques for making and modifying selections.
To make a selection with the mouse:
• Click the cursor at the desired location in the audio document and drag to select the desired range.
To extend or shorten a selection:
1. Make a selection with the mouse as explained above.
2. Hold down the Shift key and click on the end of the selection that you wish to modify.
3. Drag the mouse to extend or shorten the selection. When you are satisfied with the length of the selection, release the mouse.
Peak User’s Guide58
Page 71
To select audio between two markers:
1. Hold down the Command key () and click anywhere in between two markers. (Markers are explained in detail in the next section.) Peak selects the audio between the markers.
2. If there are additional markers in the document and you wish to extend the selection to encom­pass other portions of audio that fall between the markers, hold down the Shift key and the Command key, and click between another two markers. The selection will extend from the originally selected audio to the audio that you just added.
actually including this material in the selection itself. Peak’s Auditioning command allows you to do this by specifying a desired amount of pre-roll or post-roll when you play the selection.
To audition audio with pre-roll or post-roll:
1. Choose Auditioning from the Preference menu. The Auditioning dialog appears.
3. Repeat as desired to navigate to and select additional audio between markers.
To select audio between two markers with the Tab key:
1. Create markers at several locations in the document with one of the techniques explained in the next section.
2. Press the Tab key on your computer keyboard. Peak selects the portion of the waveform that lies between the first two markers in the document.
3. Press the Tab key again to select the portion of audio between the next two markers. (If you hold down the Shift key while tabbing the selection through the audio file, you can add each succes­sive area to the selection.)
4. Repeat as desired to navigate to and select additional audio.
To select all audio in a document:
• Choose Select All from the Edit menu or press -A on your Macintosh keyboard.

Auditioning Audio

It is often useful to audition a selection along with just a bit of audio preceding or following it—without

2. Enter the desired amount of pre-roll and post-roll and click OK.
3. Click the cursor in the audio document and drag to select the desired range.
4. Press Control-Spacebar. Peak plays the selection, adding the amount of pre-roll and post-roll that you specified.

Scrubbing

Dynamic Scrubbing
Peak provides a unique audio auditioning technique called dynamic scrubbing. This feature is very useful for precisely pinpointing and selecting a desired location in an audio document. Dynamic scrubbing allows you to drag the mouse forward or backward over a waveform while Peak plays a short loop (between 10 and 600 milliseconds) at the scrub location. When you have found the location you are looking for, you can commence editing. Peak allows you to choose the length of this playback loop with the Dynamic Scrub Time command in the Preference menu. Peak provides two type of dynamic scrubbing:
Editing
59
Page 72
dynamic shuttle scrubbing and dynamic jog scrubbing. Both are described below.
To select a loop duration for dynamic scrubbing:
• Choose Dynamic Scrub Time from the Preference menu, and choose a duration from the hierarchical submenu. Typically, a value of between 40 to 80 milliseconds works well.
Setting the Dynamic Scrub feature’s loop time
You can control the direction (forward or backward) of playback by dragging the mouse forwards or backwards. This scrubbing mode affords a greater degree of control when you are “zoomed out” in the audio document window.
To use dynamic “jog” scrubbing:
1. Hold down the Control key and Option key and drag the mouse across an area of the audio document in the audio document window. As you drag the mouse, Peak engages playback while it loops a short portion of the audio at the insertion point. Dragging the cursor farther away from the current insertion point increases the velocity of scrubbing.
2. Release the mouse button to stop scrubbing. The insertion point will be exactly where you left off scrubbing.
To use dynamic “Shuttle-type” scrubbing:
1. Hold down the Control key and click and drag the mouse across an area of the audio document in the audio document window. As you drag the mouse, Peak plays a short loop of the audio at the insertion point. You can control the tempo and direction (forward or backward) of playback by dragging the mouse slower or faster, forwards, or backwards.
2. Release the mouse button to stop scrubbing. The insertion point will be exactly where you left off scrubbing.
3. To make a selection starting at the current scrub point, stop scrubbing, hold down the Shift key, and click the mouse to extend the selection from the insertion point to the desired location.
Jog Scrubbing
Peak provides a variation of the dynamic scrubbing feature which is similar to a technique known in recording studios as jog scrubbing. With this tech­nique, Peak actually engages playback and moves through the file at its normal pace, but allows you to control the playback point by dragging the mouse.
3. To make a selection starting at the current scrub point, stop scrubbing, hold down the Shift key, and click the mouse to extend the selection from the insertion point to the desired location.
Since jog scrubbing mode is engaged by pressing the Option key in combination with the Control key, it is possible to toggle back and forth between jog and shuttle modes simply by pressing or releasing the Option key.
Tape-Style Scrubbing
In addition to dynamic scrubbing feature, Peak provides tape-style scrubbing. To enable tape-style scrubbing, set the Dynamic Scrub Time under the Preference menu to Tape-Style.
Tape-style Scrubbing requires Sound Manager version 3.3 or later. Please also note that QuickTime 4.0.1 does not support tape-style scrubbing. If you are running QuickTime 4.0.1 you will want to update to a more current version of QuickTime.
Peak User’s Guide60
Page 73
To start tape-style scrubbing:
• Hold down the Control key on your keyboard, and then click and drag the mouse at the location where you wish to begin scrubbing.
To deactivate tape-style scrubbing:
• Release the mouse and Control key.
To control tape speed in tape-style scrubbing:
1. As you drag the mouse towards the right, scrubbing speed will increase.
To undo an action:
1. Perform an edit (such as cutting audio or moving a marker).
2. Choose Undo from the Edit menu (-Z) or Toolbar. The action is undone.
3. You can continue undoing actions until you return to the original state of the audio document (the state at which it was last saved). When there are no actions left to undo, the Undo menu item will appear grayed out.
2. As you drag the mouse toward the left, scrubbing will slow down.
3. If you drag the mouse to the left of the point where you started scrubbing, the scrub direction will change from forward playback to backwards playback.
The playback bar will show the scrubbing speed at the top of the playbar. Playback speed can vary from minus four times (–4.0x) to four times (+4.0x) original playback speed.

Using Unlimited Undo and Redo

Peak maintains an internal list of the edits that you perform during the course of an editing session. These changes are not permanently applied to the file until you save it. This gives Peak unlimited undo and redo capability. Through the use of the Macintosh’s standard Undo and Redo commands, you can undo and redo your actions sequentially; or by using the Edits command, using a “playlist-style” editing event list. This powerful capability allows you to maintain complete creative freedom of choice—right up until the last moment before you save your project to disk. The only limitation in using Redo is that if you insert a new action when a redo action is available, you will no longer be able to redo. Remember, as soon as you perform an editing action other than Undo in Peak, Redo is no longer available.
To redo an action:
1. If you wish to redo the action that was undone, choose Redo from the Edit menu (-Y) or Toolbar. The action is redone.
2. You can continue redoing actions until there are none left to redo. When there are no actions left to redo, the Redo menu item will appear grayed out.

Using the Edits Command to Undo a Series of Actions

Peak’s Edits command provides you with a second unique and powerful method of undoing virtually any number of editing actions performed on an audio document since you last saved it. You can think of the Edits command as a kind of “event list-based” undo with a list of all your editing actions since you last saved. Using this list, you can navigate back in time to the point at which you performed a particular edit, and if you wish, undo it. Once you have returned to an earlier state in the project, you are free to start editing from that point on.
Be aware that if you do go back to a past action and perform a different action at that state in the project, any edits that originally occurred after will be gone, and you won’t be able to redo them.
5
Editing
61
Page 74
To use the Edits command to return to or undo an action:
1. Perform several edits. (Don’t use the Save command or you won’t be able to undo any edits that occurred before you saved.)
2. Choose Edits from the Edit menu. A dialog appears listing the edits you have performed since you last saved the document.
This section explains how to use each of these functions.
Because Peak allows you to have multiple audio documents open at the same time, it is possible to conveniently cut, copy, paste, and insert audio between documents. This makes combining material from several audio documents very fast and easy.
3. In the list, double-click on the description of the action you wish to return to (or click the Revert to Item button). Peak returns the document to the state it was in at the time of that edit.
4. If you wish to undo a particular action, locate the action that immediately precedes the one you wish to undo, and double-click it. Peak returns the document to that state.
5. When you have finished, click Done.
Please note that Peak will remain in the state of the action that you last selected in the Edits dialog. If you begin new edits from this point, you will change the original sequence of edits that followed this point in the editing session.

Scratch Disks

Because audio data can be very large, Peak utilizes a portion of your hard disk’s free space to hold audio data that has been cut or copied, as well as for temporary or scratch files for undo purposes. If you have more than one hard drive attached to your Macintosh, the Scratch Disks command in the Preference menu allows you to choose the hard drives (or “scratch disks”) that you wish to use for these temporary files. Peak allows you to select which disk you want to have as your default, or “Primary” disk for this purpose--ideally you would select the disk that has the most free space. If you are connected to a file server, you can utilize available storage on the server by clicking the Allow Servers checkbox (that is if you have a very fast server connection). Any available servers will then appear in the Scratch Disks pop-up menu. This is recommended only if you have access to a high-speed ethernet, Media Net, or other fast server.

Essential Editing Functions

Peak supports all of the Macintosh’s essential editing functions such as cut, copy, and paste and provides several more specifically designed for audio editing.
Peak User’s Guide62
The Scratch Disks dialog
Page 75

Clearing the Clipboard to Reclaim Disk Space

If you no longer need the clipboard contents, you can free up the disk space occupied by the clipboard by choosing the Clear Clipboard command from the Edit menu.
To delete a selection:
1. Click the cursor at the desired location in the audio document and drag to select the desired range.
2. Press the Delete key, or click the Delete button on the Toolbar.

Cutting Audio

The Cut command ( -X) allows you to cut a selected range out of a audio document. Audio that occurs after the cut slides over to fill in the gap. By cutting and pasting “pieces” of audio, you can freely rearrange material in an audio document. This can be a powerful tool for creating audio remixes for music-oriented applications, as well as an indispensable tool for general sound design tasks. When you cut a selection, the Macintosh holds the cut audio data in its internal memory (the Clipboard) in case you wish to paste it elsewhere. Because all real time editing you do with Peak is nondestructive, the audio isn’t actually removed from the original audio document until you finally save the file to disk with the Save command. At that time, all edits are saved and any changes that you have made are permanently saved to the audio document.
To cut a selection:
1. Click the cursor at the desired location in the audio document and drag to select the desired range.
2. Choose Cut from the Edit menu ( -X) or Toolbar.
3. The selected range is removed from the audio document(s) and held on the Clipboard. Audio occurring after the cut slides over to fill in the gap.
3. The selection is removed from the audio document. Audio occurring after the deleted section slides over to fill in the gap.

Copying Audio

The Copy command ( -C) copies the current selection to the Macintosh’s Clipboard (or internal memory buffer) so that you can paste it, insert it, or use it with optional “Clipboard-based” processing such as Add, Convolve, Mix, and Modulate. As with the Cut command, copying and pasting “pieces” of audio, allows you to freely rearrange material in a document. This can be a powerful tool for creating audio remixes for music-oriented applications, and an indispensable tool for sound design.
To copy a selection:
1. Click the cursor at the desired location in the audio document and drag to select the desired range.
2. Choose Copy from the Edit menu ( -C) or Toolbar.
3. The selection is copied to the Clipboard.
At this point, you can use either the Paste or Insert commands to place the copied audio into an audio document. Each of these commands are explained below.
5

Deleting Audio

If you wish to remove a section of audio from an audio document without using the Cut command, you can use the Delete key, or the Delete button on the Toolbar. As with the Cut command and other editing functions, the audio isn’t actually removed from the original audio document until you save the file to disk.

Pasting Audio

The Paste command ( -V) allows you to paste the contents of the Clipboard into a location that you choose by placing an insertion point. Pasting audio deletes any selected audio and inserts the clipboard audio at the insertion point. Blending can be used with the Paste command if you have made a selec-
Editing
63
Page 76
tion—the Pasted audio will be crossfaded with the audio on either side of the selection according to the Blending Envelope and Duration.
By cutting and pasting pieces of audio, you can freely rearrange material in an audio document. In musical applications, this gives you the freedom to entirely “rewrite” compositions by changing the order of things, repeating desired sections, and so on. In sound design applications, this gives you the power to “compose” with sound by creating audio collages.
To paste audio into an audio document:
1. Click the cursor at the point where you wish to paste the audio data in an audio document or make a selection of audio you want to delete and replace with the contents of the clipboard.
2. Choose Paste from the Edit menu ( -V) or Toolbar.
The Clipboard contents are pasted into the audio document(s), beginning immediately after the insertion point. Any selected audio at the location of the paste is overwritten when the pasted data is inserted into the audio document.

Replacing Audio

The Replace command allows you to paste audio data over existing audio–to paste audio into an audio document without pushing all data to the right of the insertion point farther to the right (later in time) to accommodate the newly pasted audio. The Replace command is useful for “laying over” a portion of audio while maintaining the timing of the original document.
To replace audio into an audio document:
1. Click the cursor at the point where you wish to replace the audio data in an audio document.
2. Choose Replace from the Edit menu or Toolbar. All data to the right of the replaced audio maintains their time position.

Inserting Audio

The Insert command ( -D) allows you to paste audio data into an audio document without overwriting any existing data at the insertion point. When you paste data with the Insert command, all data to the right of the insertion point or selection start is pushed farther to the right (later in time) to accommodate the newly pasted audio. The Insert command is one of Peak’s most useful tools for restructuring the contents of an audio document. It is particularly good for “composing on the fly” since it allows you to cut and insert pieces of audio—musical phrases, riffs, or simply textural sounds—to create a composition or soundscape.
To insert audio into an audio document:
1. Click the cursor at the point where you wish to insert the audio data in an audio document.
2. Choose Insert from the Edit menu ( -D) or Toolbar. All data to the right of the insertion point is pushed farther to the right (later in time) to accommodate the newly pasted range.

Cropping a Selection

The Crop command ( -`) allows you to make a selection in an audio document and quickly and easily remove all other audio from the audio document except the selection. The Crop command is a particularly useful tool for editing material to be used as samples or sound effects, since it allows you to isolate and save just the desired portion of a recording.
To crop a selection:
1. Click the cursor at the desired location in the audio document and drag to select the desired range.
2. Choose Crop from the Edit menu ( -`) or Toolbar.
All audio but the selection is removed from the audio document.

New Document from Selection

The New Document from Selection command will automatically create a new Audio Document containing
Peak User’s Guide64
Page 77
the selected audio from the source document.
To create a new document from a selection:
1. Make a selection in any open audio document that you want to have as its own document.
2. Choose Document from Selection from the New submenu under the File menu (Control--N).
3. A new audio document will be created with the selected audio.

Silencing a Selection

The Silence command ( -E) replaces the selected audio in the audio document’s selection with silence. This feature is very useful for silencing nonessential portions of a recording that contain an unusual amount of noise. This can be used very successfully with spoken material such as dialog or narration to remove noise between words or during pauses in speech. It can also be used to remove pops or clicks that occur in such material.
To silence a selection:
1. Click the cursor at the desired location in the audio document and drag to select the desired range.
The Insert Silence dialog
To insert silence of a specific duration into a docu­ment:
1. Click the cursor at the desired location in the audio document.
2. Choose Insert Silence from the Edit menu or Toolbar.
3. In the dialog that appears, enter the amount of silence that you wish to insert into the audio document.
Peak inserts the specified amount of silence into the document.
5
2. Choose Silence from the Edit menu ( -E) or Toolbar.
The selected audio is replaced with silence.

Inserting Silence into a Document

The Insert Silence command allows you to insert a specific amount of silence into an audio document at the current insertion point. This feature is very useful for inserting pauses of a desired duration into a recording, and can be particularly useful in adjusting the timing or rhythm of spoken material such as dialog or narration. When you choose this command, Peak will prompt you to enter the amount of silence you wish to insert. You can enter this value in samples, milliseconds, or seconds. All audio occurring after the insertion point is moved later in time by the amount of the silence that you insert.

Show Edits

When you enable the Show Edits command Peak indicates areas of an audio document that you have edited by enclosing these areas with hatched lines. This provides you with a convenient visual reference to portions of the document that have been affected by your editing actions. Once you save a document, the edits are saved, and these indicators will no longer appear.
To enable Show Edits:
• Choose Show Edits from the Preference menu. A check next to this item indicates it is enabled.

To disable Show Edits:
• Choose Show Edits again from the Preference menu. The absence of a check next to this item indicates it disabled.
Be aware that Blending can interfere with certain DSP processes available under Peak’s DSP menu, such as Fade In/Out and Normalize. You will typically only want to enable Blending only when you intend to make an edit in which Blending may be desirable.

Using Crossfades and Blending to Smooth Edits

Blending is an automatic crossfade function with a user-editable envelope. Peak can apply blending to areas of an audio document where they are modified by cutting, deleting, pasting, or other editing processes in order to smooth abrupt transitions between waveform amplitudes. It can be very useful for creating a smooth transition between edits that would otherwise sound too abrupt. If you are going to edit (i.e., Cut, Paste, Delete, etc.) a document, you may wish to enable blending to smooth things out a bit. You can toggle blending on or off by choosing the Blending from under the Preferences menu, or by clicking the Blend enable/disable button in the Cursor Palette (Caps Lock key) or in the Toolbar.

To select and edit the blending envelope:
1. Choose Blending from the Preference menu and click the Edit Blending Envelope button. The Blending Envelope Editor appears. The envelope shape shown here represents the shape of the crossfade. Peak also comes with several commonly used preset envelopes that appear in the pop-up at the top of all of Peak’s Envelope Editing windows (see also Editing a Fade In/Out Enve­lope). These are stored in the Peak Envelopes folder in your Peak folder.
2. Click anywhere on the line and a new moveable “breakpoint” will appear.
3. Drag the breakpoint to the desired location.
4. Continue creating and dragging breakpoints until you have created the envelope that you desire. If you wish to delete a breakpoint, click on it with the cursor and press the Delete key on your computer keyboard.
5. If you wish to reverse the shape of the envelope you have created, click the “<–>” button. This creates a mirror image of the envelope.
6. If you would like to save your custom envelope for later use, click on the Save button before exiting the envelope editor. Your custom envelopes will be stored in the Peak Envelopes folder, and will appear in the pop-up at the top of the envelope editor.
7. When you are satisfied with your new envelope shape, click Change to confirm your edits and close the envelope editor. Peak will use this envelope until you change it again.
Note that the Blending Envelope will only be applied to an edit if it is configured prior to making the edit.
If Linear Blend Calculations is checked in the Blending dialog, the Equal Power X-fade envelope is very effective for a smooth crossfade that will not result in a dip in the energy of the audio data.

Creating Fade Ins and Fade Outs

Peak allows you to create fade ins or fade outs at any point in an audio document. Fade ins/outs can be very useful for smoothly fading in or out of an audio document, or for fading out of one type of audio material into another. Very short fade ins can also be useful for smoothing or removing clicks and pops in a recording. Peak allows you to control the exact “shape” of the fade in/out by providing you with preset envelope shapes as well as very precise user­definable envelope controls for the fade. Peak also comes with several commonly used preset envelopes that appear in the pop-up at the top of the Envelope Editing windows. These are stored in the Peak Envelopes folder in your Peak folder.
To create a Fade In:
1. Click the cursor at the desired location in the audio document and drag to select the range you desire. The Fade In will be applied to the audio within this selection.
2. Choose Fade In Envelope from the Preference menu.
3. In the dialog that appears, you can use the default envelope, edit the envelope, or load any envelopes included with Peak or that you have created yourself. (“Editing Fade In/Fade Out Envelopes” is covered in the next section.)

Creating and Using Markers

Peak has a very powerful set of features to control the placement and modification of markers. Markers are locations in an audio document that you define as important. By marking specific locations in a record­ing, you can navigate easily to a location for selection, editing or playback purposes.
Markers can also be made into loops. Loops are used to sustain or repeat a section of audio. They can be used for material that you intend to transfer to a sampler, or simply for playback within Peak itself. Peak allows you to create one loop per audio file. Loops are covered in detail later in this chapter.
A marker in the Waveform Display
Creating Markers
As we’ll describe in detail on the next few pages, there are two ways to create markers: by dropping them “on the fly” during playback, or by defining them with the mouse when playback is stopped. Of the two, the mouse method is perhaps the more precise. However, since it is possible to fine tune the location of a marker at any time by dragging it (or by using the Edit Marker dialog, explained later). Both methods work equally well.
Remember that if Auto Snap To Zero is enabled the insertion point will snap to the nearest zero-crossing. This will cause your marker be placed at the nearest zero crossing when you use the mouse to create or place a marker.
Once you have created a marker, you can assign or edit the marker’s attributes in the Edit Marker dialog. Double-click the triangular base of the marker to open the Edit Marker dialog.

Text
You may wish to give markers meaningful names (up to 256 characters long) based on their locations in an audio document. Peak gives markers default numeric names based on the name of the audio document and the order in which the marker was defined. To name or rename a marker, simply type the new name in to the Text field of the Edit Marker dialog.
the insertion or deletion, so that the marker remains with the particular portion of audio you want it to be associated with. By enabling the Anchor feature for a marker, you can assure that Peak will “tie” the marker to a location on a waveform, causing it to stay with that location even when audio is inserted or deleted into the document. By default, Peak enables this feature for markers, loops and regions.
You can easily find any marker, region, or loop that you have named by simply typing the first few letters of its name. For example, if you want to locate a marker called “Solo,” just type s-o-l, and Peak will automatically scroll to the marker called “Solo.” If you hit Enter or Return after typing the characters, Peak will also automatically place the insertion point at that marker. If more than one marker matches the letters you type in, Peak will locate the first marker with that name. (Note that numerical marker name entries will only work from the keypad, not the numbers keys along the top of your keyboard.)
Marker Position
The Marker Position field allows you to move a marker to a specific time location in an audio document by entering the desired value. The pop-up menu to the right of this field allows you to choose a time format (samples, minutes:seconds:miliseconds, etc.) for the value that you enter in the Marker Position field.
Marker, Loop Start, and Loop End
These three radio-style buttons allow you to define whether the marker is a regular marker or a loop marker. If you choose to designate the marker as loop marker, you can define it as either the loop start or the loop end by clicking on the corresponding radio button. Remember, Peak allows only one loop per
audio file.
Anchor To Sample
When you insert or delete audio that is near a marker, you may want the marker to move with that particular location on the waveform. This will compensate for
Reference Point
By defining a marker as a reference point, you can use the marker as a reference when you make selections or move other markers. Selecting or dragging the marker will then automatically display the distance to the closest reference marker in whatever time format (samples or seconds) is currently selected in the Peak application. This may be useful, for instance, if you know that you want a particular sound event (such as a car door slam) to happen a certain number of seconds before or after another sound event (such as a tire squeal).
Delete Marker
The Delete Marker button allows you to remove the currently selected marker from an audio document.
The following section explains how to create markers and define their attributes.
To create a marker when playback is stopped:
1. Click the mouse at the desired location in the audio document. A dotted vertical line appears, indicating the insertion point.
2. Press -M on your computer keyboard or choose New Marker from the Action menu or Toolbar. Peak will drop a marker at that location.

Regions

To modify the length of the Region by changing the start or end:
• Drag the start or end marker of the Region in the audio document window.
Regions are portions of an audio document defined by Region Markers using the New Region command from the Action menu ( -Shift-R) or Toolbar. Regions present in currently open audio documents will be listed in the Contents window.
Peak’s use of Regions will be discussed further in the chapter on Playlists and CD Burning.
Regions can be saved only into AIFF and Sound Designer II files created by Peak. However, Peak will also read Regions stored from other programs in Sound Designer II files. The method Peak uses to store Regions in AIFF files is specific to Peak and is not necessarily supported by other software applications. If you are using Regions with other programs, you will want to store your files as Sound Designer II files.
To move a Region without changing its length:
• Hold down the Option key and drag either the start or end marker of the Region.
To edit a Region’s start, end, or length manually:
1. Double-click on either the start or end marker of the Region in the audio document window. The Edit Region dialog will appear.
2. Enter new values for Start, End, or Length times, then click OK.

Creating Loops

If you’re editing music or other rhythmically-based material, it is generally a good idea to test a selection to make sure it contains an even number of beats before you cut, copy, or paste it. A good way to do this is to loop the selection and listen to the loop as it plays. As described in the next section, Peak includes Loop Surfer, which can automate the process of finding a rhythmically “correct” length of audio to loop, assuming you know the tempo and the number of beats you wish to loop. You can also use the Loop Tuner, found in the DSP menu, to adjust the loop start and end points. The Loop Tuner is also described in the next section.
Loops are useful in material that you plan to transfer to a sampler. Loop markers created with Peak are recognized by samplers as sustain loops. Peak allows you to create only one loop per audio document.
To play a loop in Peak, select Use Loop in Playback command (-L) from the Preference menu or click the loop button on the Cursor Palette, begin playback, and when Peak reaches the loop, it will continue to repeat until you stop playback. If Use Loop in Playback is not enabled, Peak will simply play right through the loop to the end of the audio document or selection.
To create a loop from a selection:
1. Click the cursor at the desired location in the audio document and drag to select the range you want.
2. Choose Loop This Selection from the Action menu (-Shift-”-”) or Toolbar. Your selection is now looped. Loop markers appear at the beginning and end of the loop.
3. To listen to the loop, choose the Use Loop in Playback command (-L) from the Preference menu (a check next to this menu item indicates it is enabled), or click the Loop button on the Cursor
4. You can interactively fine tune a loop by dragging the loop start or end markers while loop playback is engaged. As you drag a loop marker to a new location, Peak will adjust the playback loop to reflect the changes you make. You can also use the Loop Tuner to call up a dialog that allows you to visually fine tune the loop, and even play the loop while adjusting it to listen to the changes.
To change regular markers into loop markers:
1. Create markers in a audio document.
2. Double-click on the triangular base of the marker that you wish to define as the loop start point. The Edit Marker dialog appears.
3. Click the Loop Start button and click OK. The marker becomes a Loop Start marker.
4. Double-click on the triangular base of the marker that you wish to define as the loop end point. The Edit Marker dialog appears.
5. Click the Loop End button and click OK. The marker becomes a Loop End marker. You have now defined a loop in your audio document.
To move a pair of loop markers together:
• Hold down the Option key and drag one of the loop markers to the desired location. Both markers move in tandem as you drag.
To listen to the loop only:
1. Choose Select Loop (-“-”) from the Edit menu to select the loop.
2. Make sure loop playback is enabled using the Use Loop in Playback command from the Preference menu (a check next to this menu item indicates it is enabled), or by pressing the Loop button on the Cursor Palette.
3. Press the Spacebar to begin playing back the loop.

Crossfading Loops

Peak allows you to crossfade the start and end points of a loop. Crossfading a loop can be very useful for smoothing the transition between the end of the loop and its beginning as it repeats. Peak allows you to control the envelope of the crossfade, the duration, and other parameters in the Crossfade Loop dialog.
To Crossfade a Loop:
1. Create a new loop or choose and existing loop.
2. Select the loop by -clicking between the loop markers.
3. Choose Crossfade Loop from the DSP menu or the Toolbar.
4. The Crossfade Loop dialog appears.
5. Choose where you want crossfades to be applied using the check boxes along the top of the Crossfade Loop dialog. Typically, the default for this works well.
6. Enter the Duration for the crossfade(s) in milliseconds.
7. Check whether or not you want the crossfade calculated logarithmically or not (i.e., linearly).

3. Drag the breakpoint to the desired location.
4. Continue creating and dragging breakpoints until you have created the envelope that you desire. If you wish to delete a breakpoint, click on it with the cursor and press the Delete key on your computer keyboard.
5. If you wish to reverse the shape of the envelope you have created, click the “<–>” button. This creates a mirror image of the envelope.
6. If you would like to save your custom envelope for later use, click on the Save button before exiting the envelope editor. Your custom envelopes will be stored in the Peak Envelopes folder, and will appear in the pop-up at the top of the envelope editor.
To use Loop Surfer based on a musical tempo:
1. Place the cursor where you wish to begin the loop (it’s okay to place it approximately, rather than exactly, where you wish to start).
2. Choose Loop Surfer from the Action menu (-J). The Loop Surfer dialog appears.

7. When you are satisfied with your new envelope shape, click Change to confirm your edits and close the envelope editor. Peak will use this envelope until you change it again.
To hear the completed crossfade, choose Select Loop from the Edit menu, select Use Loop in Playback from the Preference menu or click the Loop button on the Toolbar, and press the Spacebar. You will hear the loop, complete with your crossfade.

Using Loop Surfer

Peak’s Loop Surfer feature automates some of the steps for setting up loop points. Loop Surfer allows you to “Loop Surf” (adjust your loops during playback) quickly, easily and in a musically intuitive manner.
If you’re working with music, and know the music’s tempo in beats per minute, you can use Loop Surfer to create a loop which lasts for a rhythmically “correct” length of time.
The Loop Surfer dialog
3. Type in the music’s tempo. If you are not sure of the tempo, you can use the Tempo Calculator to determine the tempo. Simply select a portion of audio, and type in the number of bars and beats in the selection. The calculator will determine the tempo based on your selection. If you are unsure, and have used a drum machine or sequencer to create the music, you might wish to refer back to its settings determine the time signature and tempo. Additionally, you can use the Threshold command from the DSP menu to select a portion of audio that should correspond to the beat; see “To use Loop Surfer based on a selection” below.
4. Type in the number of beats that you wish the loop to last. The beats are based upon quarter­notes, in terms of musical time. For instance, if your song was in a 4/4 time signature, typing “4” beats would mean the loop would be one measure in length; if the song were in 7/4 time, typing “14” would mean the loop would be two measures in length. (If you are interested in exploring syncopations, however, there’s no reason why you can’t type a beat value that doesn’t correspond to
Editing
75
Page 88
the time signature, such as “5” if the music is actually in “3/4” time.)
5. If you then select the Start Surfing button (the default), Peak will automatically:
a) close the Loop Surfer dialog box; b) extend the selection from the cursor insertion point to
a calculated length, based upon the tempo and number of beats;
c) change the cursor insertion point to a Loop Start
marker;
d) drop a Loop End marker at the end of the newly
calculated selection;
e) turn on (if it hasn’t already been turned on) the Use
Loop In Playback option under the Preference menu.
f) begin looped playback of the audio selection, stopping
only once you hit your keyboard’s Spacebar or press Stop on the Toolbar.
6. If you select the Make Loop button, Peak will automatically:
a) close the Loop Surfer dialog box; b) extend the selection from the cursor insertion point to
a calculated length, based upon the tempo and number of beats;
c) change the cursor insertion point to a Loop Start
marker;
d) drop a Loop End marker at the end of the newly
calculated selection;
e) turn on (if it hasn’t already been turned on) the Use
Loop In Playback option under the Preference menu.
f) At this point, you must start playback manually using
the Spacebar or the Toolbar if you wish to begin Loop Surfing.
While you’re Loop Surfing (adjusting your loop during playback), you’re free to perform all of the standard looping functions as described in the previous section, including adjusting the Loop Start and End points during playback. Most importantly, however, since you’ll now have a selection that lasts for a period of time that matches the beat, try moving the markers in tandem, by holding down the Option key and clicking and dragging one of the loop markers to the desired location with the mouse. You’ll find it’s a great way to set up interesting rhythms and syncopations! Peak’s
interactive editing capabilities also allow you to use the Loop Surfer dialog while a loop plays to adjust the tempo, beats and so on. If you’re not working with music (or if you simply don’t know the tempo of the music you’re working with), you might choose to Loop Surf based upon a selection (or use the Threshold feature), rather than starting at a cursor insertion point.
To use Loop Surfer based on a selection:
1. Place the cursor where you wish to begin the loop, and using the mouse, select the portion of audio you wish to loop. (You can make your selection in a variety of other ways, also, as described earlier, including selecting between markers by -clicking with the mouse).
2) Select Loop Surfer from the Action menu. The Loop Surfer dialog appears.
3) If you check the Use Selection box and select either the Start Surfing or Make Loop button, Peak will automatically:
a) close the Loop Surfer dialog box; b) extend the selection from the cursor insertion point to
a calculated length, based upon the tempo and number of beats;
c) change the cursor insertion point to a Loop Start
marker;
d) drop a Loop End marker at the end of the newly
calculated selection;
e) turn on (if it hasn’t already been turned on) the Use
Loop In Playback option under the Preference menu;
f) begin looping and playing. The selection will begin
looped playback (if you have selected Start Surfing); or g) wait for you to start playback manually using the
Spacebar or the Toolbar if you wish to begin Loop
Surfing (if you have selected Make Loop).

Using the Guess Tempo and Threshold commands to find tempo

If you are working with music and don’t know the tempo–and your music has a relatively pronounced or obvious beat–you can use the Guess Tempo command to have Peak automatically guess the tempo of a selection. Make a selection and choose Guess Tempo from the Action menu. There will be a pause while Peak scans your selection and calculates the tempo for you. A dialog will then appear showing you the estimated tempo in BPM, or beats per minute. You can then enter the estimated tempo in BPM in the Loop Surfer dialog’s Tempo field or in the Audio Informa­tion dialog’s Tempo field.
You can also use the Threshold command (described later in this chapter) to define a number of markers or Regions based on amplitude peaks. If you then select audio with start and end points that correspond to these sections, you should have a selection that precisely matches the musical beat. Using Loop Surfer, you could then automate the process of looping the selection by following the steps described directly above.
Toolbar, and a dialog will appear. The waveform display in the Loop Tuner dialog shows the Start and End points of the loop, which you can visually adjust with the scroll bars at the bottom of the window. The two zoom buttons–magnifying glass icons–in the upper left of the Loop Tuner dialog allow you to adjust the vertical zoom up of the waveform. The two zoom buttons in the lower left hand corner of the Loop Tuner dialog allow you to adjust the zoom view in and out all the way down to the sample level. You can listen to the effects of the adjustments as you make them by clicking on the Play button. To exit this dialog, click on OK to accept the changes, or Cancel to leave the original loop unaffected.
5
Guess Tempo works best with audio selections that contain one full measure of audio with pronounced attacks on the beats, which appear visually on the waveform as taller sections of the audio. Using the Normalize feature on the selection prior to Guess Tempo can improve the accuracy of its deduction.
Guess Tempo is not available in Peak LE.

Using Loop Tuner

Peak’s Loop Tuner provides a way to visually line up the start and end points of your loop to get a smooth transition at the loop points. Loop Tuner also allows you listen to the effects of these adjustments as you make them. If you wish to “tune” a loop you’ve made, simply select Loop Tuner from the DSP menu or

Exporting Regions

If you have placed markers or Regions in an audio document, Peak’s Export Regions command allows you to export those regions from the source docu­ment and save each of these regions as a separate audio document. This feature is very convenient if you wish to divide a larger file into regions and transfer them as samples into a sample playback instrument, or divide a live concert record into regions and export those regions as separate files. Furthermore, you can use Peak’s Batch File Processor to process a file's

Peak allows you to edit QuickTime movie soundtracks. While you cannot edit QuickTime video in Peak, you can use Peak as a full-featured audio post-production tool for QuickTime movies. This makes Peak an ideal tool for editing and cleaning up soundtracks, as well as adding sound effects or music to QuickTime movies.

Another exciting feature of the Export Regions function is that you can Export Regions through Peak’s Batch File Processor. First configure the Batch File Processor and turn it on, then, go to Export Regions and check the Use Batch File Processor checkbox. When you begin exporting regions, each region exported will be processed by the DSP processes you choose in the Batch File Processor dialog (see Chapter 7: DSP & Plug-Ins).
Do not save the output of the Batch File Processor to input directory (i.e., a folder that is or is inside a folder of files that are being Batch Processed).
Export Regions is not available in Peak LE.
The Peak Movie Window
How to open and edit QuickTime sound tracks in Peak:
1. Select Open from the Edit menu (-O) or Toolbar.
2. In the dialog that appears, locate the QuickTime movie that you wish to open.
3. Click the Open button, and Peak will open the QuickTime movie in a movie window, and open the movie’s audio track in an audio document window. Use the QuickTime Sound Tracks from the Preferences menu to Enable or Disable the movie’s other audio tracks. You can also use this dialog to toggle multiple soundtracks contained in a movie on and off to check balances or “solo” certain tracks. Click on the Set button to accept the changes, or Cancel to leave the movie unaffected. To toggle the Movie Window on or off, choose Movie from the Window menu. A check next to this item indicates it is enabled.

4. You may now edit the movie’s audio track as you would any other audio document. The movie will “scrub” along with the audio, and the placement of the insertion point in the audio document window will also scroll the movie to that point.
5. When you are finished editing the QuickTime sound track, use Peak’s “Save As” command to save the movie with its new sound track.
Peak will not allow you to import QuickTime movies that have no audio tracks. If you want to add audio to a QuickTime movie that has no audio tracks, use MoviePlayer first to add audio tracks (even empty ones) to the movie, save the movie, and then open the movie in Peak.

Conclusion

You have now learned how to manipulate audio with Peak’s various editing tools, including how to work with Markers, Loops, and Regions. In the next chapter you will learn more about the use of Regions in Playlists.

Chapter 6: Playlists and CD Burning

Introduction

This chapter explains how to use Peak’s Playlist feature to sequence audio events. A Playlist is a list of Regions strung together in a specific order. The Peak Playlist is merely a set of instructions that tell the hard disk which regions to “read” in what order. Playlist editing does not permanently alter the original audio data on your hard disk. No matter how many changes you make, your original recordings remain intact. This type of nondestructive editing is one of Peak’s most significant and powerful features.
When you edit an audio file within Peak’s Playlist window you are not really deleting, moving, replacing, and adding actual audio as you would if you were cutting and splicing analog tape. Instead, Peak is merely creating a “map” of your audio file. This map, or “playlist,” simply describes the order in which you want portions of the recording to be played. If you’d like to hear the middle of a song first, the end next and the beginning last, then so be it. Peak will read (e.g., play) from the hard disk (where the audio data is stored) from any number of possible points desig­nated by Region markers, and these Regions can be auditioned in the Playlist in any number of possible arrangements.
Playlist editing allows you can adjust and re-sequence segments of audio (e.g., Regions) with fluidity and ease. Edits can be heard as soon as you perform them. In addition, Peak allows you to apply VST plug-ins to playlist events. Peak’s Playlist offers a fast, flexible, and powerful approach to editing and processing digital audio.
Peak also lets you burn Track At Once (TAO) and Disk At Once (DAO) audio CDs from Playlists using Roxio Toast™ (Roxio Toast Lite comes bundled with Peak). You can also use Peak’s Playlist to create a Jam Image file for burning DAO, audio CDs using Roxio’s JAM™ (JAM is sold separately). Please consult Roxio for compatible CD-Burners using either Toast or JAM. You can also bounce (i.e., write to disk) your Peak Playlist as a Sound Designer II file and then import the Playlist Events as Regions into Digidesign’s MasterList CD or Emagic’s WaveBurner.

Regions

The audio events that are played back in a Playlist are Regions—portions of an audio document defined using the New Region command from the Action menu (-Shift-R) or Toolbar. A Region is defined by Region Markers in the audio document window. All Regions defined in open audio documents will also be listed in the Contents Palette.
Two of the main windows you will use to organize Regions are the Contents Palette and the Playlist. The Contents Palette is available under the Window menu, and will show all of the regions in open audio documents at a glance. You can drag and drop Region names from the Contents Palette into the Playlist. To display all of the regions in open documents, click on the left “tab” of the named Audio Document listed in the Contents Palette. If you drag and drop an Audio Document’s name from the Contents Palette into the Playlist, it will add all the Regions in that Audio Document to the Playlist.

To move the start and end points of the region together:
• Option-drag on the start or end marker of the Region.
To change the name of a Region:
1. Double-click on either the start or end marker of the Region in the audio document window, or Option-double-click on the Region name in the Contents Palette. The Edit Regions dialog will appear.
Regions can only be saved in AIFF, Sound Designer II, and JAM Image file formats created by Peak. However, Peak will also read Regions stored from other programs in Sound Designer II files. The method Peak uses to store Regions in AIFF files is specific to Peak and is not supported by other software applications. If you are planning to use Regions created with Peak in other programs, you will usually want to save your files in Sound Designer II file format.
To define a new Region:
1. Make a selection in an opened audio document.
2. Choose New Region from the Action menu or Toolbar. The Edit Regions dialog will appear.
3. Type the name of the Region and click OK. The new Region will appear in the audio document.
To modify the length of the Region by changing the start or end:
• Drag the start or end marker of the Region in the audio document window.

2. Type the new name of the Region into the dialog and click OK.
To move a Region without changing its length:
• Hold down the Option key and drag either the start or end marker of the Region.
To edit a Region’s start, end, or length manually:
1. Double-click on either the start or end marker of the Region in the audio document window or Option-double-click on the Region name in the Contents Palette. The Edit Region dialog will appear.
2. Enter new values for Start, End, or Length times, then click OK.
To locate a Region:
• Double-click the Region you wish to locate in the Contents Palette. The audio document will scroll automatically to display the region and the Region

Creating a Playlist

To create a new Playlist:
• Select Playlist Document from the New submenu under the File menu (-Shift-P). An empty playlist document will appear. The top of the playlist has category titles for each column of information. The bottom of the playlist shows total duration of the playlist.
To add an item to the playlist:
1. Make sure the Playlist is the front-most document in Peak (-P). Select the Contents Palette from the Window menu if it is not already open.
2. Drag and drop the names of the Regions from the Contents Palette into the Playlist to add Regions to the Playlist. Each Region you add to the Playlist becomes a Playlist Event. The center of the Playlist window shows Playlist Events as a sequential list. You may use Regions from multiple audio documents. Any audio documents containing Regions used in the current Playlist must be open in Peak to be available to the Playlist.

All audio documents referenced by the Playlist must have the same sample rate, number of channels (i.e., mono or stereo), and bit-depth.
The controls along the top of the Playlist window give you access to most of the Playlist functions. There are transport controls at the top right of the window that allow you to audition the Playlist from the currently selected Region, or Playlist Event. There is a time display in the middle of the window. From left to right, the icons in the upper left of the Playlist window are Crossfade Select, Delete, Nudge Regions, Burn CD, and Bounce Playlist buttons.
Playlist Icons
A playlist event has several properties that can be modified: crossfade in, gap time, crossfade out, gain, and VST plug-ins. Since the transitions between one audio event to another can be abrupt, a playlist crossfade can be used to smooth the transition from one audio event to another.
Crossfades between Playlist Events fade out the first region while fading in the next region. Each Playlist Event has separate controls for crossfade in, crossfade out, crossfade-in time, and crossfade-out time. The curve stored in crossfade in is used to fade in the current region. The curve stored in crossfade out is used to fade out into the next region.

Crossfades are stored on disk and are computed before playback. When a crossfade is being calculated, the watch cursor may appear.

The illustration above shows how crossfades are used in playlist events. The audio material from each region overlaps beyond the region boundaries. Overlapping areas are darker in the illustration above. The white diagonal lines correspond the crossfade in and out curves. As the first region ends, the next region’s audio material begins to fade in. When the next region begins playing, the first region continues to fade out.
It is very important to understand that the Region marker in the referenced Audio Document is the exact midpoint of the fade. Consequently, there must be sufficient audio date on either side of the Region marker. That is, if you have a 60 second crossfade between two Playlist Events, there must be at least 30 seconds of audio data following the end Region marker of the first Playlist Event and at least 30 seconds of audio data proceeding the begin Region marker of the second Playlist Event.
Using the separate crossfade in and crossfade out curves, Peak provides you with the flexibility to create many common crossfade types. These include “Linear Crossfade,” “Equal Power Crossfade,” “Slow in but fast out Crossfade,” “Fast in but slow out crossfade,” and “Overlap transition.” Peak is also flexible in allowing you to control crossfade in and crossfade out durations separately. All crossfades are based on overlapping audio from the previous or subsequent regions and then mixing the overlapping material after applying the crossfade curves.
A linear crossfade actually sounds like an equal power crossfade (i.e., no loss of energy in the audio signal), since Peak playlist crossfades are calculated logarithmi­cally.
A Playlist event’s gain setting can be used to control the balance of the event in a Playlist. You may need to raise the volume or lower the volume of some Playlist events to maintain a proper balance of volume levels. You can make adjustments to the gain of individual Playlist Events as you playback the Playlist.
Be careful not to set a Playlist event’s gain too high as you may overload the signal and cause clipping to occur. You may also introduce clicks between Playlist events if the difference in gain between the two playlist events is too large. Crossfades can help smooth these transitions.
To select items in the Playlist:
• Click on the item in the Playlist that you wish to select. You may use the Shift key to select several items in the Playlist.
To hear the playlist:
• To hear your playlist, use the Play button in the Playlist window. The Playlist will begin playback from the current selected playlist event.
To preview transitions between Regions
1. Select the playlist event in which you wish to hear the transition.
2. Use the Playlist’s Play button or press the Spacebar while holding down the Command key (). The pre-roll setting from the Auditioning dialog under the Preference menu will be used to audition from the end of the previous playlist event through the transition into the selected playlist event.
To scrub in the Playlist window:
• While playing audio in a Playlist, hold down the control key and press the forward or reverse buttons in the playlist. The audio will advance "CD-style" in larger increments. Release the mouse when you find the spot you wish to hear. This is useful for moving around quickly in the Playlist's audio to test gain levels and VST effects for potential clipping. You can also click and drag right or left in the Playlist Window’s Time Display.
To select next or previous Playlist event:
• With the Playlist as the front-most window (-P), you can use the arrow keys (up and down arrows) to select the next or previous playlist event. While
86 Peak User’s Guide
Page 99
playing audio in a Playlist, you can use the arrow keys to move playback to the next or previous event in the Playlist during playback. Note that the arrow keys don't work with the control key to scrub during playback. You can also use the Tab key to select the next Playlist event, even during playback.

Modifying Playlist Events

To move items in the playlist:
• Click and drag the Playlist event to the new location. A green line will indicate the new position for the playlist event. Release the mouse button when the green line is at the location you wish to place the event.
To delete items in the Playlist:
1. Select the Playlist event you wish to delete by clicking on it.
2. Press the Delete key on your keyboard, or click on the Trash Can icon in the Playlist window. The event will be removed from the playlist, and the audio events below the event will move up. This operation will, of course, decrease the length of the Playlist.
To edit a crossfade in or out:
• Double-click on the Playlist event’s Crossfade In or Crossfade Out icon. The Fade Envelope Editor dialog will appear, where you may edit the Fade Envelope for that particular Playlist Event’s Fade In or Fade Out.

Playlists.
The default setting for crossfade duration in Peak Playlists is 0.
To modify the gap time:
• Double-click on the Playlist event Gap Time (i.e., the time between the beginning of one Playlist Event and the end of the previous one). A dialog will prompt you to enter the desired Gap Time for the selected Playlist Event.

The Nudge Regions Dialog

The Nudge Regions function is useful for fine-tuning the start and end times of Regions in the Playlist as well as adjusting the crossfade times. Access the Nudge Regions dialog by clicking on the Nudge Regions icon in the Playlist window. In this dialog you can dynamically adjust start and end times of selected regions by scrolling in the windows, and listen to the changes as you make them by clicking on the Play button.

The Nudge Regions dialog
You can set the Pre-roll and Post-roll in seconds for auditioning the crossfade. If the Preserve Timing checkbox is checked, the duration between the Region markers will remain fixed. If the Preserve Timing checkbox is not checked, the Region markers can be moved independently of one another. The Zoom tools at the left of the window allow you to zoom in to the sample level, or out for a larger view. You can also allocate region Pre-roll and post-roll times in this dialog. By clicking and dragging in the window, you can adjust the fade times for the Fade Out (on top) and the Fade In (on the bottom).
3. Configure Vbox SE with the desired VST plug-ins.
Use the Playlist VST Plug-Ins pop-up menu to take a “snapshot” of the current Vbox VST plug-ins configura­tion for a particular Playlist Event. A snapshot is the current arrangement of VST plug-ins in Vbox, along with their settings (e.g., master input and output levels, wet/dry mix, and so on).
Note that clicking may occur between Playlist Events if VST plug-ins are loaded or unloaded when changing from one snapshot to the next. This is because Vbox bypasses the audio stream when making plug-ins active or inactive. Therefore, it is recommended that if you want to use different VST plug-in configurations for each Playlist Event, configure Vbox with all the plug-ins you want to use for all Playlist Events, and then create snapshots for each Playlist Event with the plug-ins the you don’t want to use on that Playlist Event muted or bypassed.
