Abrégé
(EN)
The systems and methods described herein can be configured to identify, manipulate, and render different audio source components from encoded 3D audio mixes, such as can include content mixed for azimuth, elevation, and/or depth relative to a listener. The systems and methods can be configured to decouple depth encoding and decoding to permit spatial performance to be tailored to a particular playback environment or platform. In an example, the systems and methods improve rendering in applications that involve listener tracking, including tracking over six degrees of freedom (e.g., yaw, pitch, roll orientation, and x, y, z position).

L'invention concerne des systèmes et des procédés configurés pour identifier, manipuler, et restituer différentes composantes de source audio à partir de mixages audio 3D codés pouvant inclure un contenu mixé pour l'azimut, l'élévation et/ou la profondeur par rapport à un auditeur. Les systèmes et les procédés peuvent être configurés pour découpler un codage et un décodage de profondeur de sorte à adapter une performance spatiale à un environnement ou une plate-forme de lecture particuliers. Dans un exemple, les systèmes et les procédés améliorent la restitution dans des applications impliquant un suivi de l'auditeur, y compris un suivi à six degrés de liberté (lacet, tangage, orientation du roulis, et position sur les axes x, y et z, par ex.).
