Dynamic Range Control (DRC)
The DRC scheme has a single threshold, offset, and slope (all programmable). There is one ganged DRC for the
left/right channels and one DRC for the subchannel.
The DRC input/output diagram is shown in Figure 52.
Refer to GDE software tool for more description on T, K, and O parameters.
Professional-quality dynamic range compression automatically adjusts volume to flatten volume level.
Each DRC has adjustable threshold, offset, and compression levels
Programmable energy, attack, and decay time constants
Transparent compression: compressors can attack fast enough to avoid apparent clipping before engaging,
and decay times can be set slow enough to avoid pumping.

T = 9.23 format, all other DRC coefficients are 3.23 format
