Assigning Files to Surround Sound Channels (Automatic Method)

Compressor offers some streamlined channel assignment techniques that can save you

To assign files to surround channels with channel identifier codes


Append the channel identifier code of the target surround channel to the filename of
each source audio file. (See the list below for 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). (The channel identifier codes
must include the hyphen, as shown.)

Note: Mac OS X may add a file extension like .aiff. This will not interfere with this channel
assignment method.

This procedure works only 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.

Importing Source Media Files

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

Audio Tab Settings

for a

diagram of the Dolby audio coding modes.


Drag the renamed source audio files to the Batch window.

If the following conditions are met, Compressor automatically collapses the entire group
of files into what appears as a single surround source media file in the Batch window:

• The files in the group must be named correctly. (See the list in the previous step.)

• The total number of files in the group must be fewer than seven.
