These jobs are now ready to have a target added to them. Targets include the settings
and destinations required to make this a job that you can submit for transcoding. See

Finalizing Jobs and Submitting Batches

for information on adding targets to jobs. Also

Adding Surround Sound Source Media Files to Batches

There are two methods you can use to add audio files to a batch to create a surround
sound job: an automatic method that relies on file naming to map the audio files to the
proper channels and a manual method that allows you to manually assign the audio files
to the channels.

Each method results in a job to which you can add a setting that supports surround sound
audio outputs, such as Dolby Digital Professional, AIFF, and several audio codecs in the
QuickTime Movie output format.

Important:

Some of the output formats have multiple configurations for the surround

sound audio channels. Be sure you know which configuration your intended playback
device requires. For example, the AIFF output format provides four different configurations
for 5.1 (six-channel) audio outputs, with the difference being the order of the channels.

Assigning Files to Surround Sound Channels (Automatic Method)

Compressor offers some streamlined channel assignment techniques that can save you
time.

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.
