TRANSMITTER OF ACTIVATION SIGNAL WITH THE TIME-DEFORMATION, ACOUSTIC SIGNAL CODER, METHOD OF ACTIVATION SIGNAL WITH TIME DEFORMATION CONVERTING, METHOD OF ACOUSTIC SIGNAL ENCODING AND COMPUTER PROGRAMS Russian patent published in 2017 - IPC G10L19/10 G10L21/04 

FIELD: information technology.

SUBSTANCE: encoder comprises the window function controller (504), window organizing unit (502), device for time-deformation (506) with the final functional quality control ability, time / frequency inverter (508), TNS stage (510) or encoder quantizer (512 ), window function controller (504), device for time-deformation (506), TNS stage (510) or an additional noise filling analyzer (524) are controlled by the results of the signal analyzing obtained by time-deformation analyzer (516) or the signal categorizer (520). The decoder applies the noise filling operation using the adjusted noise filling estimation depending on a harmonic or speech sound signal characteristic.

EFFECT: increased efficiency of coding, decoding of the acoustic signal with the harmonic or speech content.
