Claim:
1. Apparatus for processing a decoded audio signal, comprising: a filter for filtering the decoded audio signal to acquire a filtered audio signal; a time-spectral converter stage for converting the decoded audio signal and the filtered audio signal into corresponding spectral representations, each spectral representation comprising a plurality of subband signals; a weighter for performing a frequency selective weighting of the spectral representation of the filtered audio signal by multiplying subband signals by respective weighting coefficients to acquire a weighted filtered audio signal; a subtractor for performing a subband-wise subtraction between the weighted filtered audio signal and the spectral representation of the decoded audio signal to acquire a result audio signal; and a spectral-time converter for converting the result audio signal or a signal derived from the result audio signal into a time domain representation to acquire a processed decoded audio signal.
