2 Choose Modify > Levels.
3 Use the slider to adjust the volume level and choose Relative or Absolute from the pop-

Changing Volume Levels While a Sequence Is Playing
You can use keyboard shortcuts to change the volume levels of clips in a sequence
while it’s playing. Your changes affect the clip on the lowest-numbered audio track
whose Auto Select control is enabled. The level of the clip at the current playhead
position is adjusted. Use the following shortcuts:
 Control-+ (plus) to raise the level by 1 dB
 Control- – (minus) to lower the level by 1 dB
When you use the shortcut, you hear a brief pause, then playback resumes
almost immediately.
