Time stretching audio clips
Time stretching lets you change the length of an audio clip without changing its pitch. This
technique is particularly helpful for fitting audio clips to video scenes or layering clips for
sound design. You can quickly time stretch a clip either by dragging or setting time stretch
properties. When you time stretch by dragging, Adobe Audition analyzes a clip’s contents
and attempts to select the most natural sounding time-stretch method. When you set
properties for time stretching, you also specify which method of time stretching to use.
Like other features in Multitrack View, time stretching is nondestructive, so you can
disable it at any time.
Note: Time stretching changes the tempo of a clip. If you time stretch a loop-enabled clip, it
won’t match the session tempo.
Dragging to time stretch a clip
To time stretch a clip by dragging:
1 In the toolbar, click the Clip Time Stretching button .
2 Select the clip, and then position the cursor over the clip’s bottom left or right handle—
the time stretch icon appears.
3 Drag the handle to lengthen or shorten the clip.
To temporarily enter time stretching mode, hold down Ctrl, and drag a clip handle.
To set time stretch properties:
1 Right-click the clip, and choose Clip Time Stretch Properties.
2 Select Enable Time Stretching, and enter a percentage in the Time Stretch text box.
