Title
(EN) AUDIO CONTROL FOR EXTENDED-REALITY SHARED SPACE
(FR) COMMANDE AUDIO POUR ESPACE PARTAGÉ DE RÉALITÉ ÉTENDUE
Abstract
(EN) Methods, systems, computer-readable media, and apparatuses for audio signal processing are presented. Some configurations include determining that first audio activity in at least one microphone signal is voice activity; determining whether the voice activity is voice activity of a participant in an application session active on a device; based at least on a result of the determining whether the voice activity is voice activity of a participant in the application session, generating an antinoise signal to cancel the first audio activity; and by a loudspeaker, producing an acoustic signal that is based on the antinoise signal. Applications relating to shared virtual spaces are described.
(FR) La présente invention concerne des procédés, des systèmes, des supports lisibles par ordinateur et des appareils pour le traitement de signaux audio. Certaines configurations consistent à déterminer que la première activité audio dans au moins un signal de microphone est une activité vocale ; à déterminer si l'activité vocale est une activité vocale d'un participant dans une session d'application active sur un dispositif ; si au moins le résultat de la détermination indique que l'activité vocale est une activité vocale d'un participant dans la session d'application, à générer un signal antibruit pour annuler la première activité audio ; et à émettre un signal acoustique au moyen d'un haut-parleur qui est fondé sur le signal antibruit. L'invention concerne des applications se rapportant à des espaces virtuels partagés.
