Abstract

En una modalidad de la presente invención se proporciona un método, dispositivo y sistema de códec, el método de codificación comprende: codificar una señal de banda completa procesada mediante eliminación de énfasis utilizando un parámetro de eliminación de énfasis determinado de acuerdo con un factor característico de una señal de entrada de audio, y enviar la señal de banda completa procesada mediante eliminación de énfasis a un extremo de decodificación, de manera que el extremo de decodificación realiza la decodificación mediante eliminación de énfasis correspondiente en la señal de banda completa de acuerdo con el factor característico de la señal de audio entrante, restaurando la señal de audio entrante; el método resuelve el problema en la técnica anterior de una alta probabilidad de distorsión de señal en una señal de audio restaurada en un extremo de decodificación, logra el procesamiento de eliminación de énfasis auto-adaptable de la señal de banda completa de acuerdo con el factor característico de la señal de audio, y mejora el rendimiento de la codificación, de manera que la señal de audio entrante restaurada en el extremo de decodificación tiene una fidelidad superior y está más cerca de una señal original.
