Other AC-3 Encoding Options

Stereo Rematrixing. Enables/Disables use of rematrixing for stereo input. This is an optional AC-3 feature that increases quality by selectively encoding the left/right channels as mid/side. This option is enabled by default, and it is highly recommended that it be left as enabled except for testing purposes.

Set lowpass cutoff frequency. If unspecified, the encoder selects a default determined by various other encoding parameters.
