Do one of the following to apply the appropriate Apple setting from the Dolby Digital
Professional category to the source audio file:

• Choose Target > New Target With Setting, choose a setting, and click Add.

• In the Batch window, Control-click in an empty part of the job, choose New Target With

Setting from the pop-up menu, choose a setting, and click Add.

• Drag a setting from the Settings tab to the source audio file’s job in the Batch window.

Make any necessary adjustments in the Inspector window and click Submit.

Compressor creates an AC-3 surround audio stream. See

About Previewing the Encoder

Settings

for information on playing your AC-3 audio files with Compressor.

You can also combine surround audio source files with a video file to make a single
Compressor job. This is useful in audio post-production workflows in which surround
audio stems (submixes) are created separately from the final picture edit. Compressor
will treat the video and up to six audio files as a virtual single asset. For example, this
would allow you to apply the Create DVD job action to make a DVD with 5.1-channel
surround sound.
