Changing the start and end points of an audio clip
You can control where an audio clip starts and ends. For example, you might trim the first 10 seconds from a 60-second audio clip so that it begins playing 10 seconds after its original start time.
To change the start or end position of an audio clip:
1 Open the Audio Editor for the audio clip you want to edit.
2 To change where the audio starts, drag the green Audio Start marker to the desired location.
3 To change where the audio ends, drag the red Audio End marker to the desired location.
