Gain generally refers to the input level
or volume in clips. Volume generally refers to the
output level or the volume in sequence clips or tracks. You can
set gain or volume levels to make levels more consistent among tracks
or clips, or to change the volume of a track or clip. Keep in mind,
however, that if the level of an audio clip was set too low when
it was digitized, increasing the gain or volume might simply amplify
noise. For best results, follow the standard practice of recording
or digitizing source audio at the optimum level; this practice allows
you to concentrate on adjusting track levels.
You use the Audio Gain command to adjust the gain level for one
or more selected clips. The Audio Gain command is independent of
the output level settings in the Audio Mixer and Timeline panels,
but its value is combined with the track level for the final mix.
You can adjust the volume for a sequence clip in the Effect Controls
or Timeline panels. In the Effect Controls panel, you use the same
methods to adjust the volume that you use to set other effect options.
It’s often simpler to adjust the Volume effect in a Timeline panel.
You control track output levels in the Audio Mixer or a Timeline
panel. Although you control track levels primarily through the Audio
Mixer, you can also do so using audio track keyframes in a Timeline
panel. Because track keyframes represent mixer automation settings,
they affect output only if automation is set to Read, Touch, or
Latch.
You can adjust the gain for an entire sequence with the Normalize
Master Track command.
