FIELD: information technologies. ^ SUBSTANCE: when coding an audio signal, noise suppression is applied to the initial audio signal to produce an audio signal with reduced noise, besides, parameter analysis is applied to the specified audio signal with reduced noise. The coding mode is selected on the basis of the specified parameter analysis results. Then the initial audio signal is coded with application of the selected coding mode. ^ EFFECT: achievement of high-quality audio signal coding with a variable bit speed. ^ 19 cl, 3 dwg |
