Audio Encoder Features

PCM Downmix from 5.1

This encoder has the ability to accept 5.1 PCM (three pairs embedded on AES or embedded)
and create a downmix before 2.0 encoding.

Onboard Audio Coding Mode, Sampling Frequencies, and AES Bit Rates

The On-boards adapters accept AES3 embedded in HD/SD serial digital video inputs.
Embedded in digital video is supported only for 48 kHz sampling, which must be
synchronous to the video.
