Applying Actions
You start working with actions by applying an action to the audio file or the currently
selected part of the file.
To apply an action:
1 With the file open in the Waveform Editor, choose an item from the Process menu.
The item appears in the Actions list.
2 Some actions have a dialog that appears when you choose the item from the Process
menu. Adjust the settings in the dialog, then click Apply.
The action is added to the Actions list, and the waveform display updates to show the
change to the audio file. You can hear the change when you play the project. Some
actions may take a moment to apply. In this case, a progress bar appears indicating
that the action is being applied.
Some effects, including reverb and delay, add audio that extends past the end of the
file. This is called an effect “tail.” When you apply a processing effect that produces an
effect tail to an audio file in the Waveform Editor, the file is lengthened to include the
tail until the point at which the tail falls below –96 dB. If you apply a processing effect
that produces a tail to a selection, the tail is mixed with the audio following the
selection. If the tail extends past the end of the file, the file is lengthened to include the
effect tail until the point at which the tail falls below –96 dB.
