Abstract  Abstract

FIELD: information technologies. ^ SUBSTANCE: wideband voice coder according to one version of realisation includes coder of low-frequency range and coder of high-frequency range. Coder of low-frequency range is arranged with the possibility to code part of wideband voice signal of low-frequency range as set of filter parametres and coded excitation signal. Coder of high-frequency range is arranged with the possibility to calculate values of coding parametres which set spectral envelope and time envelope parts of wideband voice signal of high-frequency range. Time envelope is based on excitation signal of high-range frequency produced from coded excitation signal. In one such example time envelope is based on difference of levels between part in high-frequency range and synthesized signal of high-frequency range besides synthesized signal of high-frequency range is generated according to excitation signal of high-frequency range and set of parametres of high-frequency range filter. ^ EFFECT: invention provides for expansion of narrowband voice coder to support transfer and to preserve wideband voice signals with increased throughput capacity. ^ 31 cl 46 dwg
