reduced the gain. The release threshold value can be used to set what is effectively a
minimum dynamic range, this is helpful as over limiting can reduce the dynamic range to
virtually zero and cause program material to sound “lifeless”.
In AC mode, the attack and release thresholds are set relative to full-scale. In DRC mode,
the attack threshold is set relative to the maximum volume setting of the channels mapped
to that limiter and the release threshold is set relative to the maximum volume setting plus
the attack threshold.
