Title
(EN) AUDIO AUGMENTATION USING ENVIRONMENTAL DATA
(FR) AUGMENTATION AUDIO À L'AIDE DE DONNÉES ENVIRONNEMENTALES
Abstract
(EN)
The disclosed computer-implemented method for performing directional beamforming according to an anticipated position may include accessing environment data indicating a sound source within an environment. The device may include various audio hardware components configured to generate steerable audio beams. The method may also include identifying the location of the sound source within the environment based on the accessed environment data, and then steering the audio beams of the device to the identified location of the sound source within the environment. Various other methods, systems, and computer-readable media are also disclosed.

La présente invention concerne un procédé mis en œuvre par ordinateur pour réaliser une formation de faisceau directionnelle selon une position anticipée, ledit procédé pouvant consister à avoir accès à des données d'environnement indiquant une source sonore dans un environnement. Le dispositif peut comprendre divers composants matériels audio configurés pour générer des faisceaux audio orientables. Le procédé peut également consister à identifier l'emplacement de la source sonore dans l'environnement sur la base des données d'environnement accessibles et, ensuite, à diriger les faisceaux audio du dispositif vers l'emplacement identifié de la source sonore à l'intérieur de l'environnement. La présente invention porte également sur divers autres procédés, systèmes et supports lisibles par ordinateur.
