APPARATUS AND METHOD FOR PROCESSING AN AUDIO SIGNAL USING AN ALIASING ERROR SIGNAL |
摘要 |
An apparatus for processing an audio signal comprising a sequence of blocks of spectral values, comprises: a processor (150) for calculating an aliasing-affected signal (154) using at least one first modification value (102) for a first block of the sequence of blocks and using at least one different second modification value (106) for a second block of the sequence of blocks and for estimating an aliasing-error signal (158) representing an aliasing-error in the aliasing-affected signal (154); and a combiner (152) for combining the aliasing-affected signal (154) and the aliasing-error signal (158) such that a processed signal obtained by the combining is an aliasing-reduced or aliasing-free signal (112). |
