Dynamic range compression mode
6.22.5
Limiter 1 extended attack threshold (addr 0x43)
The extended attack threshold value is determined as follows:
attack threshold = -12 + EATH1 / 4
To enable this feature, the EATHEN1 bit must be set to 1.
6.22.6
Limiter 1 extended release threshold (addr 0x44)
The extended release threshold value is determined as follows:
release threshold = -12 + ERTH1 / 4
To enable this feature, the ERTHEN1 bit must be set to 1.
