2. Click the Track buttons in the Track Selector panel in the Timeline to select the audio tracks
you want to mix down.
3. Perform an audio mixdown.
For more information on how to mix down audio, see “Mixing Down Audio Tracks” on
page 835.
The audio is mixed down, and your Avid editing application displays the new master clip in
the bin.
4. Select the mixed-down audio clip in the bin, and do one of the following:
t Select Clip > Change Sample Rate.
