Claim One:
1. A method for controlling the signal processing of an audio signal, comprising dividing said audio signal into auditory events, each tending to be perceived as separate and distinct, by detecting changes in spectral composition with respect to time, said dividing including detecting the location and strength of auditory event boundaries in said audio signal, obtaining a dynamically-changing measure of the spectral skewness of said audio signal, wherein spectral skewness is a statistical measure of the asymmetry of the probability distribution of the audio signal spectrum, modifying the strength of auditory event boundaries in response to said measure, such that the less the spectrum is skewed at the location of an auditory event boundary, the more the strength of the auditory event boundary is reduced, and controlling the signal processing in response to the location and skewness-modified strength of said auditory event boundaries.
