EFFECTIVE PRE-ECHO ATTENUATION IN DIGITAL AUDIO SIGNAL Russian patent published in 2017 - IPC G10L19/25 G10L21/02 H03M7/30 

Abstract RU 2622863 C2

FIELD: radio engineering, communication.

SUBSTANCE: method comprises: decoded signal decomposition to at least two subsignals according to a predetermined decomposition criterion; calculating attenuation coefficients relating to a sub-signal and a discrete value from a predetermined pre-echo zone; pre-echo attenuation in the pre-echo zone of each sub-signal by applying attenuation coefficients to these sub-signals; receiving the signal subjected to attenuation by combining the sub-signals subjected to attenuation.

EFFECT: reduction of pre-echo irritating effect.
