Abstract

Le système comprend une logique qui sépare les données audio reçues en données audio de canal gauche indicatrices d'un son provenant d'une source audio gauche, et données audio de canal droit indicatrices d'un son provenant d'une source audio droite. La logique sépare en outre les données audio de canal gauche en données audio principales d'oreille gauche et données audio opposées d'oreille droite; et, pour séparer les données audio de canal droit en données audio principales d'oreille droite et données audio opposées d'oreille gauche, la logique applique un premier filtre aux données audio principales d'oreille gauche, un deuxième filtre aux données audio opposées d'oreille droite, un troisième filtre aux données audio opposées d'oreille gauche, et un quatrième filtre aux données audio principales d'oreille droite, le deuxième et le troisième filtre introduisant un décalage dans les données audio opposées d'oreille droite et dans les données audio opposées d'oreille gauche, respectivement.
