Abstract
Un sistema y método codifican una señal de audio a base de objetos que comprende objetos de audio en respuesta a flujos de audio con metadatos asociados. En el sistema y el método, un procesador de flujo de audio analiza los flujos de audio. Un procesador de metadatos responde a información sobre los flujos de audio a partir del análisis por el procesador de flujos de audio para codificar los metadatos. El procesador de metadatos usa una lógica para controlar un presupuesto de bits de codificación de metadatos. Un codificador codifica los flujos de audio.
