MUMBAI, India, Sept. 12 -- Intellectual Property India has published a patent application (202517074611 A) filed by Dolby International Ab, Dublin, on Aug. 5, for 'multi-directional audio diffraction modeling for voxel-based audio scene representations.'
Inventor(s) include Terentiv, Leon; Setiawan, Panji; Fischer, Daniel; Fersch, Christof Joseph; and Werner, Markus.
The application for the patent was published on Sept. 12, under issue no. 37/2025.
According to the abstract released by the Intellectual Property India: "The disclosure relates to methods of processing audio scene information relating to a voxel- based audio scene represented by a two-dimensional projection map, for rendering audio from an audio source at a source location to a listener at a listener location. One such method includes obtaining first diffraction information relating to an acoustic path between the source location and the listener location, the listener location associated with a first voxel of the projection map; determining first direction information indicative of a first rendering direction based on the first diffraction information; retrieving prestored second diffraction information relating to an acoustic path between the source location and a second voxel of the projection map in a neighborhood of the first voxel; determining second direction information indicative of a second rendering direction based on the second diffraction information; and outputting the first direction information and the second direction information for rendering. The disclosure further relates to corresponding apparatus, computer programs, and computer-readable storage media."
The patent application was internationally filed on Feb. 23, 2024, under International application No.PCT/EP2024/054687.
