Flat Mode
In flat mode the loudness stage works as a 0dB to -15dB attenuator.
SoftMute
The digitally controlled Softmute stage allows muting/demuting the signal with a I2C-bus
programmable slope. The mute process can be activated by the I
realized in a special S-shaped curve to mute slow in the critical regions (see
Figure 7.
Please notice that a started Mute-action is always terminated and could not be interrupted
by a change of the mute -signal
