9.3Audio Objects

Display Features

The audio objects offer several display features, to help you keep track of the recording process.

The Level Meter

Audio objects have a Level Meter that depicts the input, or monitor level.

When a track armed, the Level Meter displays the input level.

The input level is also displayed less precisely, in the Arrange Window, to the left of the track number.

Peak Hold

The meter holds the peak level for a few seconds, in order to guarantee a better reading.

Clip Detector

When an input signal is strong enough to cause clipping , the top element will remain lit (“LED” lights up red). This Clip Detector can be reset, by clicking anywhere on the Level Meter.

Volume Level Control

The fader on an audio object determines the pl;ayback level . If the track is armed, the fader controls monitor level.

Midi controller #7 is used to control the fader, for instance when automating.. Moving the fader will generate CC#7 messages, as well.

Mute

An Audio object can be muted with the M-switch.Clicking on the button again will return it to the original level.

Solo for Audio Tracks

The Solo button allows you to solo any audio track. This is the S button on each audio channel strip. When engaged, any other audio objects will be muted, but Midi tracks can still be heard.

The Solo function in the Arrange window affects both audio and Midi sequences, and should be used when you want to solo an audio track so that other Midi and audio tracks are muted.

Pan/Balance

Mono objects are controlled by a pan knob, and this sets the position of the track in the stereo field.

Audio Objects

Stereo objects have a balance knob, instead. The difference between a balance control and a pan control is this: Pan sets the position of a single channel in the stereo field, whereas Balance controls the relative levels of two channels with respect to one another. When you move a mono track’s pan control all the way to the left, all of the signal is sent to the left channel. When you do the same with a balance control, only the left side of the stereo file is heard, while the right side will be silent.

Equalizer (EQ)

Adat Edit provides a three-bandequalizer to shape the sound of audio files played on the track. This raises or lowers the frequency of the signal. The three bands can regulate bass (B), midrange (M) and high frequencies(H).

Bus Sends

For each track object, there are two Bus Sends, which send signal to the bus objects. The bus objects function as auxiliary returns, and are where you insert effects to process audio.

Example: You can insert a Reverb on the insert of Bus Object 1. You can insert a Delay on Bus 2. You can use the send from each audio track to mix some signal from that track into each effect.

Basic information on this topic can be found in the section RealTime Effects on page 194.

Arming Tracks

The REC button arms a PCR track for recording. As soon as the track is armed, the button begins blinking red. During the actual recording, the button remains lit.

The REC button is only found on PCR track objects, not on the two bus objects or the output (Out1-2).

Stereo Objects

Any of the 12 available track objects can be configured as mono, or stereo. All tracks can play simultaneously. It is possible to configure 12 mono tracks, 12 stereo tracks, or any combination; but no more than 12 audio objects are available.

Both channels of a stereo recording are always dealt with together. If a Sample editor is opened for a stereo recording, then both sides will be displayed and processed at the same time.

Configuring a Stereo Object

To do this, click on the mono symbol to the left of the REC button.

Track 1 then becomes a stereo object.

One click on the stereo symbol, to the left of the REC button changes the stereo object back into an independent mono object.

9.4Real-TimeEffects

One of the new features in Adat Edit is that the CPU (Central Processing Unit) of the computer can generate effects in realtime, and these effects can be used on the audio tracks.

Introduction

Here are a few basics about signal flow in the mixer. This section can be skipped if you feel confident enough about the topic, or have a basic understanding of mixers.

There are two ways to deal with effects – with an Insert or with a Bus (this can also be called an Auxilliary Return).

Direct Insertion of Effects

A signal is fully processed when effects are inserted in the signal path. This means that 100% of the signal flows through the effect. This is practical for equalizers or dynamic effects (like compressors). This is also true for pan knobs and volume faders: they is only useful if the entire signal can flow through the effect.

Effect

Bus Effects

With this technique, a portion of the signal is sent to an Auxilliary Return. This is especially useful when working with Reverbs, Delays, and other time based effects, because you have control over the balance of “wet” (effected) and “dry” (non effected) signal.

Another advantage to this method is thast you can set up one effect, and use it to process as many tracks as you like.

path of the individual tracks (audio objects), while delay and

 

reverb can be inserted as bus effects.

 

Overview of Bus Effects

All real-timeeffects can be inserted with a long click on the Insert slot in one of the two bus objects.

Double-clickingon the activated insert slot will open the correspondingplug-inwindow. Here is where parameters for realtime effects can be set.

Delay

Delay creates echo effects.

Time

Time determines the delay time in milliseconds.

Very small values (up to 10 ms) lead to a comb filter effect, larger values (10 to100 ms) result in a doubling effect, and even larger values lead to an echo effect.

Feedback

Feedback sends the delayed signal back to the input. This is how the number or repetitions is controlled.

Real-TimeEffects

Reverb

The reverberation effect is usually used to simulate a natural space.

Room size

Room size determines the size of the simulated room. Smaller rooms have reverberations that follow more close after one another, larger rooms exhibit more time betwween reflections.

Decay

This is the time it takes for the reverb to fade out. Please note that absolute reverberation (RT60) is controlled from outside the parameter.

Density

Density is used to simulate the reflectivity of the surfaces in the room. Higher densities simulate more reflective surfaces. Setting the density too high can make the reverb sound artificial.

The surface geometry can be controlled with a combination of density andRoom size to simulate the sound of various rooms.

High-FrequencyDamping

These parameters determine high frequency content as reverberation fades away. In a natural room, reverberation is dependent on the frequency: high frequencies fade more quickly than low frequencies. Increasing the High-Frequency Damping can make your reverb sound smoother, and more natural

Using “HighFreqDamp,” room simulation can control the virtual surfaces: metal has a small value, wood has a middle value, and carpeting and curtains have high values.

Pre Delay

Pre Delay determines the time between the initial signal, and the onset of the reverb.

Pre delay can help define the reverb in your mix. Usually, ideal values run between 5 and50 ms. Very small values sound better on solo tracks, but when mixed with other tracks, these may cause the reverberation to wash the signal out. Larger values can allow you to put substantial amounts of reverb on a track, without washing it out. For instance, if youpre-delaythe reverb on a snare drum, you will hear a nive solid attack, followed by the reverb. Because the attack is fairly dry, the snare will be up front in the mix, but the decay will be nicely reverberated.

Mixer Automation

Plug-InWindow Functions

There is a row of buttons at the top of every plug-inwindow, and these correspond to theplug-infunctions.

Link

If the Link button is not activated , more than one plug-inwindow can be open at one time.

If the Link button is activated, the plug-inwindow will update to show the currently selectedplug-in.Anything doubleclicked after this point will be displayed.

Bypass

The bypass button removes the effect from the signal flow. The input signal of the effect remains unchanged, and is sent to the output.

Selecting the Audio Object

You can use this button to quickly compare the settings for the effect inserted on each bus.

9.5Mixer Automation

The term “Mixer Automation” implies the capability of recording and playing back movements of the faders, knobs, and buttons.

Fader movements—justas with Midievents—arerecorded on a track. This track will consist of a sequence with corresponding Midi events from the respective fader or knob. After being recorded, these events can be edited, just like any other Midi sequence.

The different channel tracks in the mixer create events with different Midi channels. When automation data is recorded -

The Mixer

from the adaptive mixer, the automation data is recorded to the corresponding track in the Arrange window.

Example

Let’s say you have three tracks: a bass track, a piano track (both Midi tracks), and an audio drum loop on an audio track in the Arrange window. Click on the Record button in the Transport window, and then move any fader or knob on the mixer, and automation data will be recorded. If the fader for the piano channel on the mixer is moved, Adat Edit automatically creates a new sequence on the piano track in the Arrange window. Move the volume fader for the drum loop, and a new sequence is written to the corresponding track in the Arrange window. During the recording process, it is possible to jump back and forth between the mixer channels. The mixer assigns automation data to the correct track automatically.

Mixer Automation:

-Select Windows > Open Mixer in the main menu bar.

-Click on “Record” in the Transport window.

Move the the faders, knobs, or buttons on the mixer.
