Audio decoder and method for providing decoded audio information using error concealment modifying time domain excitation signal

Abstract

audio info (220 412) an audio information (210 410) for providing decoded based on the encoded audio decoder (200 400). audio decoder comprises an error concealment (240; 480; 600) error concealment error concealment for providing audio information (242; 482; 612) for loss of the audio frame is concealed wherein the error concealment for time domain excitation signal (452; 456; 610) are modified in order to obtain error hiding audio information for one or more audio frames before the loss of audio frame is obtained.

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.
