Audio gain
Audio gain is a 16 bit value that can be set for each stereo pair going into the audio
processing block. The gain range is set to [+96dB, -96dB] with a gain step of 0.1dB.
Note that non-audio data is ignored and left unchanged by the gain function.
3.18.1 Audio embedder
The audio embedder can be enabled/disabled per group. When a group to be embedded is
disabled the audio inside that group is removed.
A 24-bit audio signal uses the Extended Audio Data Packet for the 4 least significant bits. Not
all equipment can handle Extended Audio Data Packets correctly, so the option exists to
truncate all audio data to 20 bits. This setting is common for all embedder channels.
The insertion of Audio Control Packages can also be switched on and off. This setting is
also common for all embedder channels.
