Creating 5.1-channel Audio With Monaural Materials

To use six monaural material files for 5.1-channel audio, you must use the console version of the encoder.

In this case, the order that you specify the materials in and the speaker position assignments are different from when using a six-channel audio material file.

For details, refer to the Console Encoder section.
