Selecting Output Channels
If you’re working with multichannel audio, you can adjust which tracks are assigned to
which output channels, or you can create your own multichannel file from mono tracks.
To set or change output channels for an audio track:
1 Choose 5.1 Surround from the Master Output Channel pop-up menu at the bottom of
the Audio tab.
2 Choose an output channel for the specific audio track from the Output Channel pop-up
menu (in the track list of the Audio tab).
Note: If you do not have surround-sound hardware, the Center, LFE, Left Surround, and
Right Surround output channels will be italicized. You can still select those channels
and your choices will be reflected in an exported project or playback on a system that
does have the right hardware.
Setting Track Panning
Pan refers to the left-right balance of a track in the stereo field. You can adjust a track’s
pan position using the Pan slider. The available range is from –100 (hard left) to 100
(hard right). The default is 0 (center).
To set a track’s pan position:
m In the Audio tab, the track’s HUD, or the Audio Track tab of the Inspector, drag the Pan
slider to the left or right to set the pan position for the track.
You can also type a value in the value field. You can set the pan position in integer
increments (–1, 0, 1, and so on). The pan field shows numbers in a three-digit format
(000, for example).
Locking Tracks
Locking a track prevents it from being edited. When a track is locked, you cannot mute
or solo the track, change its level or pan, move or trim it, or add keyframes. You can still
play the track, and turn it on or off.
To lock a track:
m In the Audio tab, click the lock icon on the right side of the track. Click the lock icon
again to unlock the track.
Renaming Tracks
You can also rename a track, to give it a more useful name in the project.
To rename a track:
m In the Audio tab, double-click the track’s name in the Name column, then type a new
name.
