Audio processing
Basically, you apply processing by making a selection and selecting a 
function from the Process submenu on the Audio menu. Processing is 
applied according to the following rules:
• Selecting events in the Project window or the Audio Part Editor will apply pro-
cessing to the selected events only.
Processing will only affect the clip sections that are referenced by the events.
• Selecting an audio clip in the Pool will apply processing to...

Common settings and features
If there are any settings for the selected Audio processing function, 
these will appear when you select the function from the Process sub-
menu. While most settings are specific for the function, some features 
and settings work in the same way for several functions:
The “More...” button
If the dialog has a lot of settings, some options may be hidden when 
the dialog appears. To reveal these, click the “More...” button.
To hide...

Acoustic Stamp
The Acoustic Stamp function is a convolution tool, which allows you 
to apply room characteristics (reverb) to the audio. This is done by 
processing the audio signal according to an impulse response – gen-
erally a stereo or mono recording of a very short signal (the impulse) in 
a room or other location. As a result, the processed audio will sound 
as if it were played in the same location.
This function requires a lot of processing power,...

The dialog contains the following settings:
Impulse and Envelope display
This display shows the loaded impulse response (in white) and the 
Envelope (in red). You can zoom in vertically on the impulse response 
using the slider to the right of the display (this can be useful since im-
pulse responses typically are very weak). Zooming does not affect the 
processing in any way.
Load Impulse button
Clicking the “Load Impulse” button allows you to load an...

Envelope controls
The five sliders below the display are used for setting up the “reverb 
envelope”, that is, a gain curve modifying how the impulse response is 
applied over time, and thereby the reverb character. These settings 
are reflected in the red Envelope display above. The sliders have the 
following functionality:
Filter controls
The three sliders to the right allow you to tailor the tonal character of 
the processed sound. In essence, this is a...

Wet/Dry Mix
These two sliders allow you to specify the balance between wet (pro-
cessed) and dry (original) signal in the resulting Clip.
Normally the two sliders are “reverse-ganged”, so that raising the Wet 
mix slider lowers the Dry mix slider by the same amount. However, if 
you press [Alt]/[Option] and drag a slider, you can move it indepen-
dently. This allows you to set e.g. 80% dry and 80% wet signal. Be 
careful to avoid distortion.

Envelope
The Envelope function allows you to apply a volume envelope to the 
selected audio. The dialog contains the following settings:
Curve Kind buttons
These determine whether the envelope curve should consist of spline 
curve segments (left button), damped spline segments (middle but-
ton) or linear segments (right button).
Fade display
Shows the shape of the envelope curve. The resulting waveform shape 
is shown in dark grey, with the current waveform...

Fade In and Fade Out
These function are described in the chapter “Fades, crossfades and 
envelopes” (see page 186).
Gain
Allows you to change the gain (level) of the selected audio. The dialog 
contains the following settings:
Gain
This is where you set the desired gain, between -50 and +20dB. The 
setting is also indicated below the Gain display as a percentage.
Clip detection text
If you use the Preview function before applying the processing, the 
text...

Merge Clipboard
This functions mixes the audio from the clipboard into the audio 
selected for processing, starting at the beginning of the selection.
For this function to be available, you need to have Cut or Copied a range 
of audio in the Sample Editor first.
The dialog contains the following settings:
Sources mix
Allows you to specify a mix ratio between the Original (the audio se-
lected for processing) and the Copy (the audio on the clipboard).

Noise Gate
Scans the audio for sections weaker than a specified threshold level, 
and replaces them with silence. The dialog contains the following 
settings:
Threshold
The level below which you want audio to be silenced. Levels below 
this value will close the gate.
Attack Time
The time it takes for the gate to open fully after the audio level has 
exceeded the threshold level.
Min. Opening Time
This is the shortest time the gate will remain open. If you...
