During playback, the signal passes through the Automatic Attenuator before it is filtered. The
Automatic Attenuator will attenuate all signals at the noise level in order to reduce the noise during
quiet pauses.
During record, low level input signals are brought up by the Auto Gain function if the configuration bit
D7 of CFG0 (AMT0) is set. This improves the signal to noise ratio of recorded low level input signals.
If the configuration bit CFG0<7> (AMT0) is set to ZERO, all input levels are recorded with the same
gain setting. The attack and release time of the Auto Gain and Auto Mute functions is set by the
capacitor on the ACAP pin. The AGC cannot be used if the Auto Gain or Auto Mute function is
enabled.
