CA 2578469

A listener can experience the sound of virtual loudspeakers over headphones with a level of realism that is difficult to distinguish from the real loudspeaker experience. Sets of personalized room impulse responses (PRIRs) are acquired for the loudspeaker sound sources over a limited number of listener head positions. The PRIRs are then used to transform an audio signal for the loudspeakers into a virtualized output for the headphones. Basing the transformation on the listener's head position, the system can adjust the transformation so that the virtual loudspeakers appear not to move as the listener moves the head.

Selon l'invention, un auditeur peut écouter le son de haut-parleurs virtuels au moyen d'écouteurs avec un niveau de réalisme qui est difficile à distinguer de celui des haut-parleurs réels. Des ensembles de réponses impulsionnelles spatiales personnalisées (PRIR) sont acquis pour les sources sonores des haut-parleurs au moyen d'un nombre limité de positions de la tête de l'auditeur. Les réponses impulsionnelles spatiales personnalisées sont utilisées pour transformer un signal audio destiné aux haut-parleurs en une sortie virtualisée pour les écouteurs. En fondant la transformation sur la position de la tête de l'auditeur, le système peut ajuster la transformation de façon que les haut-parleurs virtuels semblent ne pas bouger lorsque l'auditeur bouge la tête.
