METHOD AND DEVICE FOR CAPTURING AUDIO INFORMATION USING DIRECTIONAL DIAGRAM FORMATION Russian patent published in 2021 - IPC H04R3/00 G10L21/216 

FIELD: acoustics.

SUBSTANCE: device for receiving audio information contains: an array of microphones, one directional diagram generator, a set of limited directional diagram generators, the first adapter for adapting directional diagram parameters of the first directional diagram generator, the second adapter for adapting parameters of a limited directional diagram for the set of limited directional diagram generators, a difference processor for calculating the difference between limited directional diagrams. The second adapter is made with the possibility to adapt parameters of the limited directional diagram with a restriction that parameters of the limited directional diagram are adapted only for those limited directional diagram generators from the set of limited directional diagram generators, for which a measure of difference corresponding to a similarity criterion was determined, wherein the difference processor is made with the possibility to determine the measure of difference for the first limited directional diagram generator as the difference between the first set of parameters and the limited set of parameters for the first limited directional diagram generator.

EFFECT: increase in the sound quality.
