Abstract:
In some embodiments, a method for processing an audio signal in an audio processing apparatus is disclosed. The method includes receiving an audio signal and a parameter, the parameter indicating a location of an auditory event boundary. An audio portion between consecutive auditory event boundaries constitutes an auditory event. The method further includes applying a modification to the audio signal based in part on an occurrence of the auditory event. The parameter may be generated by monitoring a characteristic of the audio signal and identifying a change in the characteristic.

Claim (Index 7):
An audio processing apparatus, the apparatus comprising:\n an input interface for receiving the audio signal, the audio signal comprising at least one channel of audio content; an analysis filter bank for dividing the audio signal into a plurality of subband signals, each of the plurality of subband signals including at least one subband sample; a processor that:\n derives a characteristic of the audio signal, wherein the characteristic is a power measure of the audio signal; \n smooths the power measure to generate a smoothed power measure of the audio signal, wherein the power measure is smoothed based on a low-pass filter; \n generates a gain vector based on the location of an auditory event boundary, and \n applies the gain vector to a version of the plurality of subband signals to produce modified subband signals; and \n a synthesis filterbank that combines the modified subband signals to produce a modified audio signal.
