116 Chapter 5 Working in the Timeline
The following table shows the correspondence between semitones and musical
intervals for transposing clips:
Changing the Offset of an Audio Clip
When you add an audio clip to the Timeline, the clip plays back from the beginning of
the source audio file. The point in the audio file where the clip starts playing is called
the offset. By default, a clip’s offset is zero, the beginning of the source audio file. You
can change the offset so that the clip starts playing from a later point in the source
audio file. This allows you to use the audio from a later part of the source file without
splitting the clip.
To change the offset of a clip:
m Select the clip, then Command-Option-drag left (toward the beginning of the project).
Once you have changed the offset by dragging to the left, you can also drag to the
right to change the offset.
Note: You can only drag the offset to a later part of the clip’s source audio file, not to a
point before the beginning of the file.
