This abstract first appeared for US patent application 20250095659 titled 'EFFICIENT LOUDSPEAKER SURFACE SEARCH FOR MULTICHANNEL LOUDSPEAKER SYSTEMS
Original Abstract Submitted
an apparatus for spatial audio signal decoding and rendering associated with a plurality of speaker nodes placed within a three-dimensional space having virtual surface arrangement comprising a plurality of virtual surfaces. the apparatus determines an azimuth angle for each virtual surface of the virtual surface set and the arrange the virtual surfaces of the virtual surface set into an order based on azimuth angles to give an ordered virtual surface set. the apparatus then associates a virtual surface of the ordered virtual surface set to a search sector and starting from the associated virtual surface for the search sector, search the ordered virtual surface set to determine a virtual surface that encloses a target panning direction.
