L'invention concerne une méthode de reproduction de champ sonore qui utilise une séparation aveugle des sources et une fonction de transfert liée à la tête. Dans le système proposé, les signaux acoustiques multicanaux capturés au niveau de microphones distants sont décomposés en un ensemble de paires emplacement/signal de sources sonores virtuelles sur la base d'une analyse de composants indépendante du domaine fréquentiel. Après avoir estimé les emplacements et les signaux des sources virtuelles en convoluant les fonctions de transfert acoustique contrôlées avec chaque signal, le son spatial est construit au point sélectionné. Lors d'expériences, un champ sonore créé par six sources sonores est capturé à l'aide de 48 microphones distants et décomposé en ensembles de sources sonores virtuelles. Puisque l'évaluation subjective ne montre aucune différence significative entre le son naturel et le son reconstruit lorsque six sources virtuelles et sont utilisées, l'efficacité de l'algorithme de décomposition ainsi que la représentation de la source virtuelle sont confirmées.

Abstract: A sound field reproduction method is proposed that uses blind source separation and a head-related transfer function. In the proposed system, multichannel acoustic signals captured at distant microphones are decomposed to a set of location/signal pairs of virtual sound sources based on frequency-domain independent component analysis. After estimating the locations and the signals of the virtual sources by convolving the controlled acoustic transfer functions with each signal, the spatial sound is constructed at the selected point. In experiments, a sound field made by six sound sources is captured using 48 distant microphones and decomposed into sets of virtual sound sources. Since subjective evaluation shows no significant difference between natural and reconstructed sound when six virtual sources and are used, the effectiveness of the decomposing algorithm as well as the virtual source representation are confirmed.
