EQUIPMENT AND METHOD FOR SYNTHESIS OF SPATIALLY EXTENDED SOUND SOURCE USING INFORMATION ELEMENTS OF SIGNAL MARKS Russian patent published in 2023 - IPC H04S7/00 H04S1/00 H04S3/00 

FIELD: means for synthesizing a spatially extended sound source.

SUBSTANCE: spatial range indicator is received indicating a limited spatial range for a spatially extended sound source. One or more tag information elements are provided in response to the limited spatial range, wherein the one or more tag information elements comprise an inter-channel correlation value provided in response to the limited spatial range. The audio signal is processed using information elements of signal marks. The audio signal comprises first and second audio channels for a spatially extended audio source, or the audio signal comprises a first audio channel for a spatially extended audio source and a second audio channel is extracted from the first audio channel by a second channel processor. Correlation processing is performed for the first audio channel and the second audio channel.

EFFECT: increasing the efficiency of synthesizing a spatially extended sound source.
