METHOD OF ENCODING COEFFICIENT QUANTIZATION WITH LINEAR PREDICTION, SOUND ENCODING METHOD, METHOD OF DECODING COEFFICIENT QUANTIZATION WITH LINEAR PREDICTION, SOUND DECODING METHOD AND RECORD MEDIUM Russian patent published in 2017 - IPC H03M7/30 G10L19/00

Abstract RU 2619710 C2

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to a method of quantization. For this purpose, there is a selection based on prediction error of one of the first quantization module without interframe prediction and the second quantization module with interframe prediction without feedback and quantization of the input signal using the selected quantization module.

EFFECT: invention allows to increase quantization performance of quantization module.
