METHODS, DEVICES, AND SYSTEMS FOR SIGNAL SUBJECTED TO PRE-RENDERING FOR SOUND RENDERING Russian patent published in 2023 - IPC H04S7/00 H04S3/00 G10L19/08 

FIELD: sound processing.

SUBSTANCE: invention relates to means for sound rendering. A description of a sound scene is decoded from a bit stream, where the sound scene contains an acoustic medium. Effective sound elements from the description of the sound scene are determined, where effective sound elements incapsulate impact of the acoustic medium and correspond to virtual sound objects representing the sound scene. Information of effective sound elements, indicating positions of effective sound elements, is determined based on the description of the sound scene. An indication of a rendering mode is decoded from the bit stream, indicating, whether effective sound elements represent a sound field received from sound elements subjected to pre-rendering, and whether their rendering should be performed using a preset rendering mode. In response to the indication of the rendering mode, indicating that effective sound elements represent the sound field and that their rendering should be performed using the preset rendering mode, rendering of effective sound elements is performed using the preset rendering mode.

EFFECT: increase in the efficiency of sound rendering.
