Clips can contain one audio channel (mono), two audio
channels—left and right (stereo), or 5 audio surround channels with
a low-frequency effects audio channel (5.1 surround). Although a
sequence can accommodate any combination of clips, all the audio
is mixed to the track format (mono, stereo, or 5.1 surround) of
the master track.
Premiere Pro lets you change the track format (the grouping of
audio channels) in an audio clip. For example, sometimes you may
want to apply audio effects differently to the individual channels
in a stereo or 5.1 surround clip. You can change the track format
in stereo or 5.1 surround clips so that the audio is placed on separate
mono tracks when the clips are added to a sequence.
Note: You can change a master clip’s track format only before you
add an instance of the clip to a sequence.
Premiere Pro also lets you remap the output channels or tracks
for a clip’s audio channels. For example, you can remap the left
channel audio in a stereo clip so that it’s output to the right
channel.
