Selecting Tracks for Audio Scrubbing
By default, all monitored audio tracks are selected for scrubbing. However, as the play speed
increases during audio scrubbing, some monitored audio tracks are dropped. You can select up to two
tracks to ensure they play during scrubbing, even if the system has to drop some tracks.
The following table shows how many tracks you can scrub at the varying speeds of play.
To ensure an audio track is monitored during scrubbing:
t Enable the Active/Inactive button in the Track Control panel for the selected track.
Active/Inactive buttons, displaying a black border to indicate tracks that can play without dropping audio information
The Active/Inactive button displays a black border to indicate which tracks can be played if the
system has to drop tracks during audio scrubbing. By default, the two top Active/Inactive buttons
display black border.
You can isolate specific audio tracks for scrubbing without having to deselect monitoring of all
other audio tracks by soloing the audio tracks. See “Soloing Audio Tracks” on page 252.
To make a track the primary active track:
t Alt+click the Audio Track Monitor button for the selected track.
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.
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 121.

Normal speed 8 tracks
Two times normal speed 8 tracks
Three times normal speed 2 tracks
Greater than three times normal speed 0 tracks
