Patent ID: 7574313

Claim:
A device for processing an information signal, comprising: a unit for converting a time representation of the information signal to a time/spectral representation of the information sicinal, by block-wise transforming of the time representation of the information signal; a unit for converting the time/spectraI representation of the information signal to a spectral/modulation spectral representation by means of a single frequency decomposition transform, wherein the unit for converting the time/spectral representation is designed such that the spectral/modulation spectral representation depends on both a magnitude component and a phase component of the time/spectral representation of the information signal; a unit for manipulating the spectral/modulation spectral representation of the information signal to obtain a modified spectral/modulation spectral representation; and a unit for forming a processed information signal representing a processed version of the information signal based on the modified spectral/modulation spectral representation.
