DEVICE, METHOD AND RELATED SOFTWARE FOR ERRORS CONCEALMENT SIGNAL GENERATING WITH COMPENSATION OF CAPACITY Russian patent published in 2018 - IPC G10L19/05 G10L19/09 

FIELD: data processing.

SUBSTANCE: invention relates to audio coding, and in particular to audio coding based on LPC-like processing in the context of code books. Errors concealment signal generating device comprises: a LPC representation generator for generating a LPC substituting representation; gain calculator for gain information calculating by LPC representations; compensator for the LPC substituting representation gain effect compensating using gain information and a LPC synthesizer for the codebook information filtering using a LPC substituting representation to obtain an error concealment signal, wherein the compensator is made with possibility to multiply to the codebook information weight factors or the LPC synthesizer output signals.

EFFECT: providing an improved concept for the errors concealment signal generating.
