Near-transparent or transparent multi-channel encoder/decoder scheme Abstract A multi-channel encoder/decoder scheme additionally preferably generates a waveform-type residual signal (16). This residual signal is transmitted (18) together with one or more multi-channel parameters (14) to a decoder. In contrast to a purely parametric multi-channel decoder, the enhanced decoder generates a multi-channel output signal having an improved output quality because of the additional residual signal.

Système de codage/décodage multicanal, qui, de préférence, produit de façon supplémentaire un signal résiduel du type à forme d'onde (16). Ce signal résiduel est transmis (18) avec un ou plusieurs paramètres multicanal (14) à un décodeur. Contrairement au décodeur multicanal purement paramétrique, le décodeur amélioré décrit dans l'invention produit un signal de sortie multicanal à qualité de sortie améliorée, par la présence du signal résiduel supplémentaire.
