Abstract
The present subject matter provides technical solutions to technical problems facing audio virtualization. To reduce the technical complexity and computational intensity facing audio virtualization, a technical solution includes rendering audio objects binaurally with differing quality levels, where the quality level for each audio source may be selected based on their position relative to the user's field of view. In an example, this technical solution reduces technical complexity and computational intensity by reducing the audio quality for audio sources outside of a user's central field of vision. In an example, high quality audio rendering may be applied to sound objects within this strong central visual acuity area. These technical solutions reduce processing over higher complexity systems, and provides potential for much higher quality rendering at a reduced technical and computational cost.
