Abstract  Abstract

An audio decoder for providing a decoded audio information on the basis of an encoded audio information the audio decoder comprising: an error concealment configured to provide an error concealment audio information for concealing a loss of an audio frame wherein the error concealment is configured to modify a time domain excitation signal obtained for one or more audio frames preceding a lost audio frame in order to obtain the error concealment audio information; wherein the error concealment is configured to obtain a pitch information describing a pitch of the audio frame preceding the lost audio frame and to provide the error concealment audio information in dependence on the pitch information; and wherein the error concealment is configured to obtain the pitch information on the basis of the time domain excitation signal associated with the audio frame preceding the lost audio frame.
