Performing Digital Audio Scrub
To locate an audio edit point by using digital scrub:
1. Solo an audio track for scrubbing and adjust the output volume, if necessary.
2. Press the Caps Lock key to activate digital audio scrub.
You can also activate digital audio scrub by pressing and holding the Shift key while you
drag the position indicator or click the Step buttons as described in step 3.
3. Move through the material in one of the following ways to hear the scrub:
t Drag the position indicator.
t Click the Step buttons to step through in fixed increments: 1 frame backward, 1
frame forward, 10 frames (8 frames for 24p) backward, or 10 frames (8 frames for
24p) forward.
Step Buttons. Left to right: 1 frame backward, 1 frame forward, 10 frames (8 frames for 24p)
backward, or 10 frames (8 frames for 24p) forward
4. When you find the correct frame, mark the location, trim the transition, or perform any
other function you choose.
When you sample incoming frames (with the default scrub parameters, for example),
the system places the position indicator at the head of the last sampled audio point.
When you sample outgoing frames, the system places the position indicator at the tail of
the last sampled audio point.
Audio Displays in the Timeline
You can display audio waveforms in the Timeline to help you visually locate points in an
audio track for editing or trimming. Waveforms for stereo tracks in the Timeline display
waveforms for both channels within a single track, separated by a horizontal divider. For
more information, see “Displaying Audio Waveforms” on page 750.
