110 Chapter 5 Working in the Timeline
To move an audio clip to a new track:
m Drag the clip up or down to a different track.
You can also move an audio clip using the Left and Right Arrow keys with various
modifier keys. Using the Option key with the Arrow keys moves the clip by one pixel at
a time; using the Option and Shift keys with the Arrow keys moves the clip to the next
gridline in the Timeline.
When you move a clip by one pixel, the amount the clip moves in time depends on the
current zoom setting.
To nudge an audio clip in pixel increments:
m Hold down the Option key while you press the Left or Right Arrow key.
To nudge an audio clip to the next gridline:
m Hold down the Option and Shift keys while you press the Left or Right Arrow key.
Snapping Clips to Clips on Adjacent Tracks
If snap is turned on, you can snap a clip to the edges of a clip in an adjacent track (the
track either directly above or directly below the track containing the clip). This is
especially useful when the start and end points of clips do not fall on the current
Snap To value.
To snap a clip to adjacent clips:
m Choose View > Snap To > Adjacent Tracks.
Resizing Audio Clips
You control the duration of an audio clip (the amount of time the clip plays back) by
resizing the clip. When you add a clip to the Timeline, the clip has the same duration as
the source audio file. You can shorten clips to play back only a part of the source file.
When you lengthen a clip with looping playback mode, it repeats the source file
multiple times.
