Performing Smooth Audio Scrub
You can use three-button play with the J-K-L keys to perform smooth audio scrubbing of
selected tracks of audio at variable speeds but not digital audio scrub. You can monitor while
stepping (jogging) or while shuttling at fixed rates up to three times normal speed. The audio
cuts out at greater than three times the normal speed and comes back in after the speed drops
below three times.
(Symphony) You can also use the mouse to perform smooth audio scrubbing of selected tracks.
Mouse Jog lets you move the position indicator with the mouse. Mouse Shuttle lets you control
the speed of the position indicator by dragging the mouse. You can jog and shuttle using the
mouse but, unlike three-button play, playback rates using the mouse do not occur at fixed
increments. They can vary all the way from 1 to 300 fps, depending on manipulation of the
mouse.
To monitor audio with three-button play:
1. Select the correct track, and adjust the playback volume as necessary.
2. Play the audio by using the three-button variable speed playback procedures described in
“Playing Footage with the J-K-L Keys (Three-Button Play)” on page 512.
(Symphony) To monitor audio with the mouse:
1. Select the correct track, and adjust the playback volume as necessary.
2. Activate the mouse for jogging or shuttling by pressing the Mouse Jog button or the Mouse
Shuttle button.
Both buttons are available in the Play tab of the Command palette and can be mapped to an
editing button under the Record monitor.
To deactivate jog or shuttle, press the space bar or the Escape key.
3. Play the footage with the mouse.
Adjusting Digital Scrub Parameters
The default parameters for the number of frames you hear as you scrub are zero frames of
outgoing audio (behind the position indicator) and one frame of incoming audio (ahead of the
position indicator). To isolate frames for marking or trimming, the default parameters are
sufficient.
You can increase these settings to include more frames of audio on either side — for example,
when you want to sample whole words or parts of words as you scrub to find edit points within a
phrase. You can also reverse the settings to sample frames behind the position indicator
