Abstract
A system for processing audio data is disclosed that includes a plurality of gain adjustment devices, each gain adjustment device having an associated audio input frequency band. A plurality of control signal processing systems are configured to receive audio input data for one of the associated audio input frequency bands and to generate a gain adjustment device control signal. The gain adjustment device control signal is configured to decrease a gain setting of an associated gain adjustment device for a predetermined period of time as a function of a transient in the associated audio input frequency band.
