ALC Threshold (Address 1Eh)
Maximum Threshold (MAX[2:0])
Default: 000
Function:
Sets the maximum level, relative to full-scale, at which to limit and attenuate the input signal at the attack
rate.
Minimum Threshold (MIN[2:0])
Default: 000
Function:
Sets the minimum level at which to disengage the ALC’s attenuation or amplify the input signal at a rate set
in the release rate register until levels again reach this minimum threshold. The ALC uses this minimum as
a hysteresis point for the input signal as it maintains the signal below the maximum as well as below the
minimum setting. This provides a more natural sound as the ALC attacks and releases.
