Claim:
1. A system for processing audio data comprising: a plurality of gain adjustment devices, each gain adjustment device having an associated audio input frequency band; a plurality of control signal processing systems, each control signal processing system configured to receive audio input data for one of the associated audio input frequency bands and to generate a gain adjustment device control signal; a clipping system configured to receive the audio input data and to generate a clipped audio input signal; a high pass filter coupled to the clipping system and configured to receive the clipped audio input signal and to generate high-pass filtered clipped audio data; a scaler multiplier coupled to the high pass filter and configured to multiply the high-pass filtered clipped audio data by a predetermined value; and a table coupled to the scaler multiplier and configured to receive a difference signal and to select the predetermined value as a function of the difference signal, wherein 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.
