TH137251B - Equipment and methods for processing decoded audio signals in the spectrum domain. - Google Patents

Abstract

A device for processing decoded audio signals (100) that includes a filter (102) for filtering the decoded audio signals to obtain a filtered audio signal (104), a time-spectrum converter. Step (106) for converting the decoded audio signal and The audio signal is filtered to Corresponding spectral representative Each spectral representative has a number of sub-band signals, a weighted counterpart (108) for the frequency-selective weighting operation of the filtered audio signal by multiplying the sub-band signal by each weighted coefficient to Obtaining a filtered audio signal And weighted; minus (112) for sub-band sub-band deletion operation between audio signals being Filtered and weighted And spectral representative of the decoded audio signal and spectral-time converter (114); For converting the output audio signal Or the signal derived from The resulting sound signal is representative. Time domain for obtaining decoded audio signals. Processed (116)
