APPARATUS AND METHOD FOR ISOLATING SOURCES USING SOUND QUALITY ASSESSMENT AND CONTROL Russian patent published in 2022 - IPC G10L25/30 

FIELD: computing technology.

SUBSTANCE: invention relates to the field of computing technology for processing audio data. The technical result is achieved by determining the estimated target signal depending on the input audio signal; determining the resulting values, depending on the estimated sound quality of the estimated target signal, in order to obtain one or multiple parameter values; and forming an isolated audio signal, depending on the one or multiple parameter values and depending on one of the estimated target signal, the input audio signal, and the estimated difference signal; wherein the estimated difference signal is an estimate of a signal containing only a section of the difference audio signal, wherein the isolated audio signal is formed depending on the parameter values and depending on the linear combination of the estimated target signal and the input audio signal; or wherein the isolated audio signal is formed depending on the parameter values and depending on the linear combination of the estimated target signal and the estimated difference signal.

EFFECT: maximum reduction of noise level on the condition of absence of artifacts.
