Audio decoder and decoded audio information providing method using error concealment to modify time domain excitation signal and providing decoded audio information

摘要

An audio decoder (200; 400) for providing a decoded audio information (220; 412) on the basis of an encoded audio information (210;410). The audio decoder comprises an error concealment (240; 480; 600) configured to provide an error concealment audio information (242;482;612) for concealing a loss of an audio frame, wherein the error concealment is configured to modify a time domain excitation signal (452,456;610) obtained for one or more audio frames preceding a lost audio frame, in order to obtain the error concealment audio information.
