DIFFRACTION SIMULATION BASED ON FINDING PATH ON GRID Russian patent published in 2024 - IPC H04S7/00 A63F13/54 G06T15/10 G10K15/08 

FIELD: data processing.

SUBSTANCE: invention relates to a method of processing audio content to generate sound in a three-dimensional audio scene, taking into account diffraction effects caused by elements of the three-dimensional audio scene. In particular, the present invention relates to a method for acoustic diffraction simulation based on finding a path on a grid. Present invention further relates to a corresponding device and a computer-readable data medium. In the disclosed method of processing audio content for forming in a three-dimensional audio scene, the audio content comprises a sound source at a source position. Method includes obtaining a voxelized representation of a three-dimensional audio scene, wherein the voxelized representation indicates volumetric elements in which sound can propagate, and volumetric elements that obstruct sound, generating a two-dimensional projection map for the audio scene based on the voxelized representation by applying a projection operation, which is used to project onto a horizontal plane, to the voxelized representation, and determining parameters indicating the position of the virtual source based on the position of the source, the position of the listener and the projection map for simulation by generating a signal of a virtual source from the position of the virtual source of action in the form of acoustic diffraction by a three-dimensional audio scene on the source signal relating to the sound source at the position of the source.

EFFECT: creation of a method and a device for processing audio content for providing realistic sound generation in virtual three-dimensional audio scenes, including blocking elements.
