106 Chapter 6 Working in the Timeline
To move the crossfade without changing its length:
m Drag the lower area of the crossfade left or right.
As with other edits you make in the Timeline, creating a crossfade between two audio
clips does not change the source audio files.
Truncating Overlapping Audio Clips
You can have Soundtrack truncate the overlapping part of audio clips in the Timeline
instead of crossfading them. To truncate audio clips, you set the project to truncate
mode, then drag an audio clip so that it overlaps another clip.
To set the project to truncate mode:
m Click the Overlap Mode button, located above the Global Timeline view.
In truncate mode, when you drag an audio clip so that it partially overlaps another
audio clip in a track in the Timeline, the overlapped part of the clip is truncated.
To truncate an audio clip:
m In the Timeline, drag another audio clip over part of the clip.
Splitting and Joining Audio Clips
You may want to use only part of the source audio file in an audio clip. Soundtrack lets you
split the clip into segments and use the segments in the Timeline as independent clips.
You can move the segments, edit them, and split each one into additional segments.
There are two ways to split clips: using the Split (razor) tool, or using the Split menu
item in the Edit menu with the playhead. Each method has advantages, depending
on the situation. Using the Split tool, you can perform many splits consecutively
without moving the playhead each time. Using the playhead, you can split clips in
several tracks at once.
To split audio clips with the Split tool:
1 Click the Split Tool (also called the Razor) button above the Timeline.
2 Click a clip at the point where you want to split it.
