Abstract
In view of improving the perceived sound quality of a decoded speech signal, in a method and device for post-processing a decoded speech signal, the decoded speech signal is divided into a plurality of frequency sub-band signals, and post-processing is performed on at least one of the frequency sub-band signals. Applied. After post-processing of the at least one frequency sub-band signal, the frequency sub-band signals are added to produce a post-processed decoded speech signal output. By this method, post-processing can be performed only on a desired sub-band or sub-band group, and other sub-band groups can be substantially unchanged.
