摘要
An audio decoder (100; 300) for providing a decoded audio information (112;312) on the basis of an encoded audio information (110; 310) comprises an error concealment (130; 380; 500) configured to provide an error concealment audio information (132;382;512) for concealing a loss of an audio frame following an audio frame encoded in a frequency domain representation (322) using a time domain excitation signal (532). This time domain excitation signal is modified by time-scaling it in dependence on a prediction of a pitch for the time of the one or more lost audio frames.
