Selecting Part of an Audio File
When you apply an action to an audio file in the File Editor, the action is applied to the
entire file unless you select part of the file. You can select different parts of the audio
file and apply different actions to each selection.
To select part of an audio file:
m In the waveform display, drag horizontally across the part of the waveform you want
to select.
Some actions can only be applied to a selection. The selection can contain the entire
audio file.
To select the entire audio file:
m Choose Edit > Select All.
You can select one channel (left or right) of a stereo audio file and apply actions to only
the selected channel. You can also select only part of one channel.
To select the left channel of an audio file:
