DEVICE FOR QUANTIZATION OF LINEAR PREDICTIVE CODING COEFFICIENTS, SOUND ENCODING DEVICE, DEVICE FOR DEQUANTIZATION OF LINEAR PREDICTIVE CODING COEFFICIENTS, SOUND DECODING DEVICE AND ELECTRONIC DEVICE TO THIS END Russian patent published in 2017 - IPC G10L19/24 G10L19/38 G10L19/107 G10L19/12 G10L19/05 

FIELD: electronics.

SUBSTANCE: invention relates to quantization of linear predictive coding coefficients. Device for quantization of a speech or an audio signal comprises: selection module configured to select basing on a prediction error one of the first sampling unit and the second unit of sampling by open circuit; the first sampling unit is configured to input signal sampling, including, at least, one of the speech signal or the audio signal without an interframe prediction; the second sampling unit is configured to input signal sampling with the interframe prediction.

EFFECT: technical result is higher efficiency of quantization of an audio or a voice signal by selecting the optimum quantization module.
