Abstract  Abstract

An audio decoder (200; 400) for providing decoded audio information (220; 412) based on encoded audio information (210; 410), the audio decoder comprising: a concealment (240; 480; 600 ) Error configured to provide audio error concealment information (242; 482; 612) for hiding a loss of an audio frame, where error concealment is configured to modify a signal (452,456; 610) of time domain excitation obtained for one or more audio frames preceding a lost audio frame, in order to obtain the error concealment audio information; where the error concealment (240; 480; 600) is configured to obtain height information describing a height of the audio frame preceding the missing audio frame, and to provide the information (242; 482; 612) of error concealment audio according to height information; where the audio decoder is characterized in that the error concealment (240; 480; 600) is configured to obtain the height information based on the time domain drive signal (452; 456; 610) associated with the frame audio that precedes the lost audio frame.
