 Audio Coding Mode pop-up menu: Specifies the audio channels of the encoded
stream. This setting also has an Automatic button.
For example, “3/2 (L, C, R, Ls, Rs)” means three front channels (left, center, right) and
two rear (surround) channels. “2/0 (L, R)” is essentially a standard stereo file. The
audio coding mode affects settings such as the available bandwidth and surround
channel preprocessing. If you click the Automatic button (next to the Audio Coding
Mode pop-up menu), Compressor makes its best guess at the intended audio coding
mode, based on available source audio files.
Note: In the Audio Coding Mode pop-up menu, “S” stands for a single rear
“Surround” channel.
 Enable Low Frequency Effects checkbox: Select this option to include the LFE channel
in the encoded stream. (Not available for 1/0 mono or 2/0 stereo.)
 Sample Rate pop-up menu: Specifies the sample rate. All files intended for video and
audio DVD authoring must have a 48 kHz sample rate as per the DVD specification.
The 32 kHz and 44.1 kHz sample rates are only available when Generic AC-3 is the
target system.
Choose the audio channel
grouping for the encoded
stream from the Audio
