ENCODING DEVICE AND ENCODING METHOD Russian patent published in 2012 - IPC G10L19/08 

FIELD: information technology.

SUBSTANCE: encoding device includes a shape quantisation module (111), having: an area search module (121) which searches for the pulse for each of the bands into which a predetermined search area is divided; and a full search module (122) which performs pulse search on entire search area. The shape of the input spectrum is quantised based on a few positions of pulses and polarities. The amplification quantisation module (112) calculates pulse amplification sought by the shape quantisation module (111), and quantises amplification for each of the bands.

EFFECT: providing sufficiently good audio quality, preferably for aural perception, even if the number of data bits is small.
