EFFICIENT RENDERING OF VIRTUAL SOUNDFIELDS
This abstract first appeared for US patent application 20240414493 titled 'EFFICIENT RENDERING OF VIRTUAL SOUNDFIELDS
Original Abstract Submitted
an audio system and method of spatially rendering audio signals that uses modified virtual speaker panning is disclosed. the audio system may include a fixed number f of virtual speakers, and the modified virtual speaker panning may dynamically select and use a subset p of the fixed virtual speakers. the subset p of virtual speakers may be selected using a low energy speaker detection and culling method, a source geometry-based culling method, or both. one or more processing blocks in the decoder/virtualizer may be bypassed based on the energy level of the associated audio signal or the location of the sound source relative to the user/listener, respectively. in some embodiments, a virtual speaker that is designated as an active virtual speaker at a first time, may also be designated as an active virtual speaker at a second time to ensure the processing completes.
