ALC Release Rate (Address 2Bh)
ALC Threshold (Address 2Ch)
Sets the rate at which the ALC releases the analog and/or digital attenuation from levels below the
MIN[2:0] threshold

Notes:
1. The ALC release rate is user-selectable but is also a function of the sampling frequency, Fs, and the
2. The Release Rate setting must always be slower than the Attack Rate.
Sets the maximum level, below full scale, at which to limit and attenuate the input signal at the attack rate
