In digital audio, received bit streams of compressed audio data might be corrupted due to error-prone transmission channels. During decompression, errors will be propagated towards the audio output. Concealing these errors allows to minimize the resulting obtrusive deteriorations. The paper describes techniques for concealing transmission errors in ISO/MPEG-2/4 AAC digital audio signals by exploiting specific audio signal characteristics. These techniques have been successfully applied to both simulation and real-time processing.
