Title (EN) PREDICTIVE HEAD-TRACKED BINAURAL AUDIO RENDERING
(FR) RENDU AUDIO BINAURAL À SUIVI DE TÊTE PRÉDICTIF
Abstract:
(EN) Methods and apparatus for predictive head-tracked binaural audio rendering in which a rendering device renders multiple audio streams for different possible head locations based on head tracking data received from a headset, for example audio streams for the last known location and one or more predicted or possible locations, and transmits the multiple audio streams to the headset. The headset then selects and plays one of the audio streams that is closest to the actual head location based on current head tracking data. If none of the audio streams closely match the actual head location, two closest audio streams may be mixed. Transmitting multiple audio streams to the headset and selecting or mixing an audio stream on the headset may mitigate or eliminate perceived head tracking latency.
(FR) L'invention concerne des procédés et un appareil de rendu audio binaural à suivi de tête prédictif dans lesquels un dispositif de rendu rend de multiples flux audio de différentes positions de tête possibles sur la base de données de suivi de tête reçues d'un casque d'écoute, par exemple des flux audio de la dernière position connue et d'une ou de plusieurs positions prédites ou possibles, et transmet les multiples flux audio au casque d'écoute. Le casque d'écoute sélectionne et lit ensuite l'un des flux audio qui est le plus proche de la position de tête courante sur la base de données de suivi de tête courantes. Si aucun des flux audio ne correspond étroitement à la position de tête courante, deux flux audio les plus proches peuvent être mélangés. La transmission de multiples flux audio au casque d'écoute et la sélection ou le mélange d'un flux audio sur le casque d'écoute peuvent atténuer voire éliminer la latence de suivi de tête perçue.
