APPARATUS, METHOD AND CORRESPONDING COMPUTER PROGRAM FOR GENERATING AN ERROR CONCEALMENT SIGNAL USING INDIVIDUAL REPLACEMENT LPC REPRESENTATIONS FOR INDIVIDUAL CODEBOOK INFORMATION Russian patent published in 2018 - IPC G10L19/05 G10L19/06 

FIELD: information technology.

SUBSTANCE: invention relates to means for generating an error concealment signal using individual replacement representations. Apparatus for generating an error concealment signal comprises an LPC (linear prediction coding) representation generator for generating a first replacement LPC representation and a different second replacement LPC representation; an LPC synthesizer for filtering a first codebook information using the first replacement representation to obtain a first replacement signal and for filtering a different second codebook information using the second replacement LPC representation to obtain a second replacement signal; and a replacement signal combiner for combining the first replacement signal and the second replacement signal to obtain the error concealment signal.

EFFECT: technical result is improved sound quality.
