Abstract
Three-dimensional (3D) audio content creation and rendering systems and methodologies are presented here. A disclosed method of processing 3D audio assigns audio source objects to 3D video objects, links audio tracks to assigned audio source objects, and performs wave field synthesis on the linked audio tracks to generate 3D audio data representing a 3D spatial sound field. A disclosed method of processing 3D audio during playback of 3D video content obtains 3D audio data and 3D video data for a frame of 3D video content, applies device-specific parameters to the 3D audio data to obtain transformed 3D audio data scaled to a presentation device, and processes the transformed 3D audio data to render audio information for an array of speakers associated with the presentation device.
