Abstract
(EN)
The present disclosure pertains to an apparatus, which has circuitry configured to control a loud- speaker arrangement including at least one virtual loudspeaker and at least one real loudspeaker to generate at least one virtual sound source, wherein the at least one virtual sound source is generated based on contributions of the at least one virtual loudspeaker and the at least one real loudspeaker, and wherein a soundfield modulation function configured to generate an acoustic impression for a user is used to modulate a soundfield emitted by the virtual sound source, such that the acoustic impression is generated at a predetermined position.
(FR)
La présente invention concerne un appareil, qui a des circuits configurés pour commander un montage de haut-parleur comprenant au moins un haut-parleur virtuel et au moins un haut-parleur réel pour générer au moins une source sonore virtuelle, l'au moins une source sonore virtuelle étant générée sur la base de contributions du ou des haut-parleurs virtuels et du ou des haut-parleurs réels, et une fonction de modulation de champ sonore configurée pour générer une impression acoustique pour un utilisateur est utilisée pour moduler un champ sonore émis par la source sonore virtuelle, de telle sorte que l'impression acoustique est générée à une position prédéterminée.
