Title (EN) RENDERING AUDIO OBJECTS HAVING APPARENT SIZE
(FR) RESTITUTION D'OBJETS AUDIO AYANT UNE TAILLE APPARENTE
Abstract:
(EN) Methods, systems, and computer program products for rending an audio object having an apparent size are disclosed. An audio processing system receives audio panning data including a first grid mapping first virtual sound sources in a space and speaker positions to speaker gains. The first grid specifies first speaker gains of the first virtual sound sources in the space. The audio processing system determines a second grid of second virtual sound sources in the space, including mapping the first virtual sound sources into the second virtual sound sources of the second virtual sources. The audio processing system selects at least one of the first grid or second grid for rendering an audio object based on an apparent size of the audio object. The audio processing system renders the audio object based on the selected grid or grids.
(FR) L'invention concerne des procédés, des systèmes et des produits programmes informatiques permettant de restituer un objet audio ayant une taille apparente. Un système de traitement audio reçoit des données de panoramique audio comprenant une première grille mappant des premières sources sonores virtuelles dans un espace et des positions de haut-parleur à des gains de haut-parleur. La première grille spécifie des premiers gains de haut-parleur des premières sources sonores virtuelles dans l'espace. Le système de traitement audio détermine une seconde grille de secondes sources sonores virtuelles dans l'espace, comprenant le mappage des premières sources sonores virtuelles à l'intérieur des secondes sources sonores virtuelles des secondes sources virtuelles. Le système de traitement audio sélectionne au moins l'une de la première grille ou de la seconde grille pour restituer un objet audio sur la base d'une taille apparente de l'objet audio. Le système de traitement audio restitue l'objet audio sur la base de la ou des grilles sélectionnées.
