The purpose of the invention is to bridge the gap between pa-rametric multi- channel audio coding and matrixed-surround multi-channel coding by gradually improving the sound of an up-mix signal while raising the bit-rate consumed by the side-information starting from 0 up to the bit-rates of the parametric methods. More specifically, it provides a method of flexibly choosing an "operating point" somewhere between matrixed-surround (no side-information, limited audio qual-ity) and fully parametric reconstruction (full side- information rate required, good quality). This operating point can be chosen dynamically (i.e. varying over time) and in response to the permissible side- information rate, as it is dictated by the individual application.

La présente invention concerne une logique destinée à combler l'écart entre le codage paramétrique de l'audio multicanal et le codage multicanal de l'ambiophonie matricée par une amélioration graduelle du son d'un signal de confusion tout en augmentant le débit binaire consommé par l'information annexe, allant de 0 jusqu'aux débits binaires des procédés paramétriques. L'invention concerne plus particulièrement un procédé permettant de choisir de façon souple un "point de fonctionnement" quelque part entre l'ambiophonie matricée (aucune information annexe, qualité audio limitée) et la reconstruction totalement paramétrique (nécessité de débit complet pour information annexe, bonne qualité). Ce point de fonctionnement peut être choisi de façon dynamique, c'est à dire avec des variations dans le temps, et en réaction au débit d'information annexe possible, en fonction des besoins de l'application considérée.
