Error Concealment in the Spectral Domain

Document Thumbnail

Today's high quality low bit-rate coders work on a spectral representation of the audio signal using perceptual noise shaping strategies. Thus, single channel errors affect a block of data in the reconstructed audio signal. Efficient error concealment techniques working in the spectral domain can be employed to avoid annoying error artefacts. A new approach to this problem is developed and first results are presented.
