| 摘要 |
The present invention relates to the concealment of errors in decoded acoustic signals caused by encoded data representing the acoustic signals being partially lost or damaged during transmission over a transmission medium. In case of lost data or received damaged data a secondary reconstructed signal is produced on basis of a primary reconstructed signal. This signal has a spectrally adjusted spectrum (Z4<E>), such that its spectral shape deviates less from a spectrum (Z3) of a previously reconstructed signal than the spectrum (Z'4) of the primary reconstructed signal. <IMAGE> |
