Abstract
Se describen un aparato para el procesamiento de una señal de audio y el método para el mismo. La presente invención incluye recibir la señal de audio y la información pre-configurada, obtener la matriz pre-configurada de la presente información, en donde la matriz pre-configurada indica el grado de contribución del objeto al canal de salida; y ajustar el nivel de salida del objeto usando la matriz pre-configurada. En consecuencia, sin la configuración del usuario para cada objeto, si se seleccionan los metadatos pre-configurados para ser aplicados a una señal de audio con referencia a los metadatos pre-configurados en conjunto previamente, los niveles de los objetos incluidos en la señal de audio se pueden ajustar fácilmente usando los datos que se vuelven pre-configurados que corresponden a los metadatos pre-configurados seleccionados.
