DEVICE AND METHOD FOR RENDERING AUDIO SCENE USING ALLOWABLE INTERMEDIATE DIFFRACTION PATHS Russian patent published in 2023 - IPC H04S7/00 H04R1/34 

FIELD: audio processing.

SUBSTANCE: provide a plurality of intermediate diffraction paths through a plurality of diffracting objects. The intermediate diffraction path has a starting point and an exit edge of the plurality of diffracting objects and the associated filter information. Render the audio source at the listener position. At the same time, based on the output edges of the intermediate diffraction paths and the position of the listener, one or more allowable intermediate diffraction paths are determined from the position of the audio source to the position of the listener through a plurality of diffracting objects. For each allowed intermediate diffraction path, a filter representation for the full diffraction path from the audio source position to the listener position is determined using a combination of associated filter information for the allowed intermediate diffraction path and filter information describing the propagation of the audio signal from the output edge of the allowed intermediate diffraction path to the listener position.

EFFECT: increase in audio processing efficiency.
