APPARATUS, METHOD, OR COMPUTER PROGRAM FOR ESTIMATING THE TIME DIFFERENCE BETWEEN CHANNELS Russian patent published in 2021 - IPC G10L19/08 

Abstract RU 2762302 C1

FIELD: computing technology.

SUBSTANCE: invention relates to the field of computing technology for processing audio data. The technical result is achieved by estimating the characteristics of the signal of a first channel, or the signal of a second channel, or both signals, or the signal obtained from the signal of the first channel or the signal of the second channel; calculating the cross-correlation spectrum for the time block from the signal of the first channel in the time block and the signal of the second channel in the time block; weighing the smoothed or non-smoothed cross-correlation spectrum to obtain a weighted cross-correlation spectrum using a first weighing procedure or using a second weighing procedure depending on the estimated characteristics of the signal, wherein the first weighing procedure is different from the second weighing procedure; and processing the weighted cross-correlation spectrum to obtain the time difference between the channels.

EFFECT: increase in the accuracy of estimating the time difference between channels between two signals of channels.
