with the closest DAC sample rate.
If set, the circuit will never apply gain to
the signal, no matter how small, but it
will attenuate the signal as soon as it
reaches target and release it at the
decay rate, once signal level reduces
below target. The I
the time the LIMITER is enabled) is the
maximum gain that the ALC will apply.
Care should be taken when choosing
the optimum I
enabling the Limiter.
If set, the ALC circuit uses the stereo
average of the input signals to control
the gain of the stereo output. This
maintains stereo imaging. If this bit is
cleared, then both channels operate as
dual mono.
