When for an external audio source VU-meter mode is enabled (bits AVUM or COMP are logic 1) the HTC
setting controls the t
When for an external audio source dynamic compression is enabled (bit COMP is logic 1) the MTC setting
controls the t
The attack time is the time, which the weak signal processing needs to realize a full control change for a
level voltage change between HIGH level (where the weak signal processing is inactive) and 0.75 V level
voltage.
The recovery time is the time needed for the full control change when the level voltage rises from 0.75 V to
HIGH level.
