 - `reference` is the reference level for the AGC. It tries to keep the amplitude of the output signal close to that.
 - `attack_rate` is the rate of decreasing the signal level if it gets higher than it used to be before.
 - `decay_rate` is the rate of increasing the signal level if it gets lower than it used to be before.
