Channel Word Length
If in HD mode, the default value for all ChXX-XXWordLen
parameters is 24-bits. In SD mode, it is 20 bits.
In SD mode if at least one channel is set to 24-bits, the corresponding
embedder will enable 24-bits embedding.
Channel Fade Rate
The channel fade rate is a single control for all output channels. This
feature is only applied to output channels operating in PCM format. It is
automatically disabled for individual output channels operating in
Non-PCM format.
