Assigning Files to Surround Sound Channels (Automatic
Methods)
Compressor offers some streamlined channel assignment techniques that can save you
time.
To assign files to surround channels with channel identifier codes
1
Append the channel identifier code of the target surround channel to the filename of
each source audio file. (See the list below for a list of the appropriate channel identifier
codes.)
• -L: Left front channel
• -R: Right front channel
• -C: Center front channel
• -Ls: Left surround channel
• -Rs: Right surround channel
• -S: Center surround channel
• -LFE: Low frequency channel (Subwoofer, LFE)
For example, to assign an AIFF file to the left surround channel, rename the file as
filename-Ls.aiff (where filename is the name of your file).
Note: Mac OS X may add a file extension like .aiff. This will not interfere with this channel
assignment method.
This procedure only works when you drag and drop files into the Batch window. If you
drag the files onto the Compressor application icon, they will appear as separate source
files, each in its own job.
Note: If you are creating Dolby Digital Professional (AC-3) surround sound streams, you
will not use all the channels listed in the table at once. See
for a
diagram of the Dolby audio coding modes.
2
Drag the renamed source audio files to the Batch window.
