DEVICE AND METHOD OF GENERATING EXPANDED SIGNAL USING INDEPENDENT NOISE FILLING Russian patent published in 2018 - IPC G10L19/28 

Abstract RU 2667376 C2

FIELD: audio equipment.

SUBSTANCE: invention relates to the processing of an audio signal. Device comprises the following: the display means for displaying the initial portion of the spectrum of the input signal to the target portion in the portion of the expansion spectrum, the initial portion of the spectrum contains the noise filling section; and the noise filler, which is configured in order to generate first noise values for the noise-filling portion in the initial portion of the spectrum of the input signal and for generating the second noise values for the noise portion in the target portion, wherein the second noise values are decorrelated from the first noise values, or in order to generate the second noise values for the noise portion in the target portion, wherein the second noise values are decorrelated from the first noise values in the initial portion.

EFFECT: technical result is to ensure the formation of an expanded signal from the input signal.
