Clipping the end of a sound
The sound clip you imported is a bit longer than you need. You’ll shorten the sound
file by using the Edit Envelope dialog box. Then you’ll apply a fade so the sound
gradually decreases as it ends.
1 Select the first keyframe of the sounds layer.
2 In the Properties inspector, click the Pencil button.
The Edit Envelope dialog box appears, showing you the sound’s waveform.
The top and the bottom waveform are the left and right channels of the sound
(stereo). A timeline is between the waveforms, a pull-down menu of preset
effects at the left corner, and view options at the bottom.
