Patent

CA 2635985

A method for sy nthesizing a binaural audio signal, the method comprising: inputting a parametrically encoded audio signal comprising at least one combined signal of a plurality of audio channels and one or more corresponding sets of side information describing a multi-channel sound image; and applying a predetermined set of head-related transfer function filters to the at least one combined signal in proportion determined by said corresponding set of side information to synthesize a binaural audio signal.

L'invention concerne un procédé permettant de synthétiser un signal audio binaural, consistant: à faire entrer un signal audio à codage paramétrique comprenant au moins un signal combiné composé d'une pluralité de canaux audio et d'un ou plusieurs ensembles correspondants d'informations annexes décrivant une image sonore multi-canaux, puis à appliquer un ensemble prédéterminé de filtres à fonction de transfert liés à la tête audit signal combiné selon une proportion déterminée par l'ensemble correspondant d'informations annexes afin d'obtenir un signal audio binaural de synthèse.
