Abstract

La presente invención divulga un método, un aparato, y un sistema para procesar datos de audio, y pertenece al campo de las tecnologías de comunicaciones. El método incluye: obtener una trama de ruido de una señal de audio, y descomponer la trama de ruido actual en una señal de ruido de banda baja y una señal de ruido de banda alta; y codificar y transmitir la señal de ruido de banda baja al utilizar un primer mecanismo de transmisión discontinua, y codificar y transmitir la señal de ruido de banda alta al utilizar un segundo mecanismo de transmisión discontinua. De acuerdo con la presente invención, se utilizan diferentes maneras de procesamiento para la señal de banda alta y la señal de banda baja, se pueden guardar cargas de cálculo y bits codificados bajo una premisa de no bajar la calidad subjetiva de un codec, y los bits que se guardan pueden ayudar a alcanzar un objetivo de reducir un ancho de banda de transmisión o mejorar la calidad general de codificación.
