1 Instructions in brief

1.1 What's new in Nero Wave Editor?

In comparison with the first version of the software, Nero Wave Editor has a number of new and enhanced features, such as support for DirectX and VST plug-ins. In addition, an overview of the existing processing steps allows you to return quickly to any stage of the process, and crossfading allows you to create professional recordings without pauses and hissing noises. The high quality Declicker which suppresses the individual hissing and clicking noises from records and the Decrackler which removes constant background crackling are just two of the great new features.

Of course, Nero Wave Editor is non-destructive, which means that the original file is not modified. As well as protecting the original file, this also speeds up the work, as the changes do not need to be saved individually and are implemented in real time. You only save your new audio file once you are happy with the results of your editing. If Nero Wave Editor should crash before you have saved your file, you can use the crash restore function to restore the most recent version of your work when you restart the program.

Another new feature is the automatic separation of tracks which can then be stored in new files.

Nero Audio Plug-in-Manager 6.0 reads and writes files in the following formats: 'wav', 'mp3', 'wma' and 'aiff'. You need an additional license to be able to create an unlimited number of MP3 files, which you can obtain from Nero AG.

Nero Wave Editor's new effects include a wah-wah filter (a bandpass filter which allows the center frequency to be changed over time), a phaser which allows a signal to be combined with a phase-shifted version of itself, voice modification with which you can modify vocals to create interesting results and pitch tuning, which corrects the intonation of vocal or instrumental recordings.

Another new feature is band extrapolation, which makes old and dull sounding recordings seem fresher by generating high frequencies and corresponding basses to extend the frequency spectrum. Band extrapolation can also be used to improve MP3 recordings with a very low bit rate. Using the filter toolbox allows interference frequencies can be filtered out. The Karaoke filter removes the human voice from stereo recordings in which the voice has been mixed in the center of the stereo field, which allows the original song to be saved without the vocals. With the stereo processor the stereo field can be corrected and the stereo effect artificially amplified.

1.2 Introduction

These brief instructions are aimed at putting you in the position where you can quickly create your own audio files or to edit existing ones. Because this is a sizeable and powerful program, only the main points are dealt with here and some parts of the program are not explained in detail (or at all).

1.5 Important terms

A number of important terms relating to audio files are explained below. The choice of sampling rate and bit depth has a significant influence on the quality of the recording.

Bit depth / resolution

Sampling rate The sampling rate indicates how often an analog-digital

In principle, audio data is made up of periodic vibrations, which can be illustrated by a curve. The resolution shows exactly how the sampling value of a curve should be determined. The higher the resolution, the more exactly this can be done.

converter determines the sample value from an analog signal. This is measured in sample values per second (Hertz, often abbreviated as Hz). In this case it is also true that the higher the sampling rate, the more accurate the results.

2 About Nero Wave Editor

2.1 Introduction

Nero Wave Editor is a user-friendly program for editing and recording audio

files, which may be of the 'wav', 'mp3' or 'aiff' format. The other types of format that can also be read by Nero Wave Editor depend on the plug-ins that have been installed.

Individual audio-files can be created quickly and easily using the various filters and sound optimization methods.

Nero Wave Editor is started by: Start > Programs > Nero > Nero 6 > Nero Wave Editor.

2.2 Structure of the program

Nero Wave Editor's structure corresponds to that of the usual Windows elements: a menu bar, various toolbars and a status bar. The Nero Wave Editor workspace shows the selected audio file.

The individual elements of the window are arranged clearly and understandably, making Nero Wave Editor very easy to use.

Nero Wave Editor About Nero Wave Editor • 8

2.2.1 Workspace

The Nero Wave Editor workspace comprises three separate elements: the 'Sound Display', the 'Level Meter' and 'Spectrum Analyzer'.

The 'Sound Display' shows a graphic image of the audio file that is currently open.

The 'Level Meter' regulates how the open audio file is played.

The 'Spectrum Analyzer' displays the bandwidth of the open audio file (in decibels - dB).

3.1 Selecting the input and output devices

To be able to record and reproduce audio files, a soundcard is needed. If a number of components that can play audio files have been installed, select the desired device.

1. In the 'Options' menu, select the 'Device Settings' command. The standard devices set in the control panel will be selected.

If you wish to specify another device, click on the corresponding dropdown button and highlight the desired device.

2. Click on the 'OK' button to save the devices chosen.

3.2 Setting the editor options

A number of various general 'Editor Options' can be configured. This area comprises four 'tab' (index) cards. By clicking with the mouse you can bring one of the index cards to the forefront and edit the settings.

Click on the 'OK' button to save the and close the dialog. 'Cancel' closes the dialog without saving the changes. 'Apply' saves the changes, though without closing the dialog so that additional changes can be made to the settings on other index cards. 'Help' starts the online help feature.

3.2.1 Setting the display features

The display options for the sound display can be changed on this index card.

1. In the 'Options' menu, select the 'Editor Options' command.

2. Click on the 'View' index card and specify whether the following control fields should be activated or disabled:

 Show axis to the left of the audio visualization

 Show time rules above the audio visualization

 Always keep the playback position in the window whilst playing

3.2.2 Specifying the directories used

The directories relevant for Nero Wave Editor can be specified on this index card.

1. In the 'Options' menu, select the 'Editor Options' command.

2. Click on the 'Directories' index card and specify:

 The directory for the intermediate storage of the temporary files

 The directory in which the presettings are located

 The directory in which the plug-in files are located

by clicking on the

button and selecting the appropriate directory.

3.2.3 Audio output

The settings for audio output can be specified on this index card.

1. In the 'Options' menu, select the 'Editor Options' command.

2. Click on the 'Audio Output Settings' index card and specify whether the following control fields should be activated or disabled:

 Use noise shaping when converting to lower bit depths

 Use dithering when converting to lower bit depths

 Specify the bit resolution on the dropdown button and highlight the number

of bits wanted.

Dithering and noise shaping are used to minimize noise disturbance at low resolutions. Noise shaping shifts the disturbance to bandwidths that the human ear cannot hear particularly well. Dithering adds a quiet noise signal so that there is no longer any correlation between the desired signal and the noise signal causing the disturbance.

4.3 Zooming

With Nero Wave Editor, audio files can be both horizontally and vertically zoomed, so that special parts of the audio files or marked elements within them can be viewed in more detail.

4.3.1 Vertical zoom

The vertical zoom determines the height of the curve progression displayed and can be changed by selecting the desired zoom setting.

The vertical zoom setting can only be changed if the vertical zoom bar is displayed. If it is not visible, it can be displayed via the 'View' menu and the 'vertical zoom bar' command.

The following example shows the 100% zoom, i.e. levels from –100% to +100% of the maximum levels.

Selecting the 200% zoom reduces the displayed levels to –50% to +50% of the maximum levels.
