Abstract
An audio processing apparatus includes a digital filter, a signal combiner, and a dynamic-range processor (DRP). The digital filter is configured to receive a filter-input audio signal and to filter the filter-input audio signal, so as to produce a filter-output audio signal. The signal combiner is configured to combine the filter-input audio signal with the filter-output audio signal, so as to produce a combined audio signal. The DRP is configured to apply to the filter-output audio signal a dynamic-range correction that depends non-linearly on the combined audio signal.
