Dynamic Range Control (DRC)
The DRC scheme has a single threshold, offset, and slope (all programmable). There is one ganged DRC for the
high-band left/right channels and one DRC for the low-band left/right channels.
The DRC input/output diagram is shown in Figure 40.
See the GDE software tool for more description on the T, K, and O parameters.
Professional-quality dynamic range compression automatically adjusts volume to flatten volume level.
Each DRC has adjustable threshold 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
