1138 Chapter 13 Working with Audio
Looping an Audio Clip
Another way of extending a clip’s duration is by looping it. You can easily loop a clip by
adjusting it in the Timeline. When a looped audio clip reaches its last frame, the audio
starts playing again from its first frame.
To loop an audio clip:
1 Move the pointer close to the Out point of the audio track in the Timeline.
2 Press and hold down the Option and Shift keys.
The pointer turns into the loop pointer.
3 Drag the Out point of the layer’s bar to the left.
As you drag, the tooltip displays the clip’s In and Out points, duration and loop
duration. A looped clip has barriers to indicate where loops begin and end in the
Timeline.
The first loop barrier in a clip’s bar is interactive. Moving the barrier changes the point
at which the clip loops.
To change the loop point of an audio clip:
m Drag the first loop barrier left or right.
The end point of the clip’s loop moves as you drag.
Using Markers with Audio
When you add project markers to the Timeline, they appear in all three tabs of the
Timing pane: the Timeline, the Keyframe Editor, and the Audio Editor. You can use
project markers to designate “hit points” as you play back the project, to quickly jump
to a specific point in time, or to highlight points where you want to synchronize visual
and audio events.
