Abstract

La présente invention concerne un procédé de décodage de signal audio, permettant une décompression et un transfert plus efficace d'un signal audio. Ce procédé consiste à recevoir un signal audio ou avec un signal d'information spatiale, à obtenir des informations de localisation utilisant le numéro de fenêtre temporelle et un paramètre de signal audio, à obtenir des informations de localisation au moyen du numéro de fenêtre temporelle et du paramètre de signal audio et, à établir un signal audio multicanal en appliquant un signal d'information spatiale au signal de mélange-abaissement et en effectuant un réseau multicanal pour un signal audio multicanal en réponse au canal de sortie.
