Partial spectral loss concealment in transform coders
A novel error concealment technique for partial spectral loss in transform coders is presented. Based on amplitude and phase inter- and intra-frame correlations, an algorithm for missing spectral coefficient restoration is derived. The algorithm restores the missing spectral coefficients by predicti...

| description | A novel error concealment technique for partial spectral loss in transform coders is presented. Based on amplitude and phase inter- and intra-frame correlations, an algorithm for missing spectral coefficient restoration is derived. The algorithm restores the missing spectral coefficients by predicting the amplitude using energy matching and the phase using group delay conservation principles. Results from listening tests illustrate the performance of the proposed algorithm. |
