Adjusting Volume in the Timeline
Add Keyframe button
Fast Menu button
To use Audio Gain Automation to adjust volume:
1.  Select an audio track for adjusting volume.
2.  Click the Timeline Fast menu button, and select Audio Auto Gain.
  If there is audio volume data on a clip and Audio Auto Gain is not chosen from the Timeline Fast menu, the system displays a pink triangle on the clip to indicate that audio volume data is present but not displayed.
  You can enable Audio Clip Gain, Audio Auto Gain, and Sample Plot in the Timeline Fast menu to display audio information superimposed over waveform plots in the Timeline.
3.  (Option) Expand the audio track by doing one of the following:
  Press and hold Ctrl+L (Windows) or Command+L (Macintosh).
  Press and hold the Ctrl key (Windows) or the Option key (Macintosh) while dragging in the Track Selector panel. When the pointer changes to a cross, drag the cross to expand or shrink the track.
4.  Click the Add Keyframe key on the keyboard (N) or the Add Keyframe button on the Tool palette to add keyframes along the Timeline. The Avid system adds a keyframe to each enabled track.
A straight line appears in the selected audio track. The line shows the current gain level for that track in the Audio Mix tool.
  You adjust gain in the Automation Gain tool by dragging keyframes in the Timeline or by placing the position indicator on a keyframe and adjusting the slider.
After you add the first keyframe to a segment, you can adjust the gain for the entire clip. When you move the keyframe up or down, the corresponding Volume Level slider in the Automation Gain tool also moves.
