Adjusting Audio Gain Using Keyframes

Audio gain automation (also called audio rubberbanding) allows you to

change a segment’s audio gain by adding and manipulating keyframes in

the Timeline.

When you add a keyframe, the system adds the point at the level currently

set for that track in the Audio Mixer tool. Adding multiple keyframes allows

you to ramp the gain up and down within any segment.

To prepare tracks to add and manipulate keyframes:

1. (Optional) Change the Audio Mixer mode to Auto, because you will now

be performing auto gain adjustments, rather than clip gain adjustments.

(To do so, simply click the Audio Mixer Mode button, which toggles it to

Auto mode.)

2. In the Timeline, select the audio tracks you want to adjust.

3. Do one of the following:

 To apply global auto gain settings: In the Timeline Fast menu, select

Audio Data > Auto Gain.

 To apply local (specific track) auto gain settings: In the Timeline

Fast menu, select Audio Data > Allow Per Track Settings.

 In the Timeline Fast menu, select Track Control Panel. (You can

also access the Track Control panel by clicking the small arrow

above the Track Selector panel, to the right of the Timecode dis-

play.) The Track Control panel appears to the right of the record

track selectors.
