3.3.5.1 AGL

Automatic gain limiting is an enhanced DRC function available in many of the TAS58xx devices. AGL uses a feedback topology to compress an incoming audio signal if it is above the AGL threshold. A softening filter is used to remove harmonics during the compression. The attack/release times can be tuned to change how quickly an audio signal is compressed/released.
