The present invention relates to the technical field of communications. Disclosed are an audio data processing method, device and system. The method comprises: obtaining a noise frame of an audio signal, and resolving the current noise frame into a noise low-band signal and a noise high-band signal; coding and transmitting the low-band signal according to a first discontinuous transmission mechanism; and coding and transmitting the high-band signal according to a second discontinuous transmission mechanism. According to the present invention, by processing the high-band signal and low-band signal in different manners, the computation complexity is lowered and coding bits are saved without reducing the subjective quality of a codec; the saved bits contribute to a lower transmission bandwidth or higher overall coding quality. |
