Abstract
La presente invención proporciona un método, un aparato y un sistema de procesamiento de señales de audio de multicanal, y se relaciona con el campo de tecnologías de codificación y decodificación de audio, para resolver un problema en la técnica anterior de que una señal de audio no puede ser transmitida de forma discontinua en un sistema de comunicación de audio de multicanal. Un codificador incluye una unidad de detección de señales y una unidad de codificación de señales. La unidad de codificación de señales se configura para: cuando la unidad de detección de señales detecta que una Nésima señal de mezcla descendente de trama incluye una señal de voz, codifica la Nésima señal de mezcla descendente de trama; o cuando la unidad de detección de señales detecta que la Nésima señal de mezcla descendente de trama no incluye una señal de voz: codifica la Nésima señal de mezcla descendente de trama si la unidad de detección de señales determina que la Nésima señal de mezcla descendente de trama cumple con una condición de codificación de audio preestablecida, u omite la codificación de la Nésima señal de mezcla descendente de trama si la unidad de detección de señales determina que la Nésima señal de mezcla descendente de trama no cumple con una condición de codificación de trama de audio preestablecida. En esta solución técnica, debido a que la codificación en una señal de mezcla descendente es discontinua, se resuelve el problema en la técnica anterior de que la señal de audio no puede ser transmitida de forma discontinua.
