Abstract

La invención presenta un dispositivo codificador de audio que comprende: un codificador de audio configurado para producir un flujo de bits de audio codificado a partir de una señal de audio que comprende tramas de audio consecutivas; un codificador de control del rango dinámico configurado para producir un flujo de bits codificado para el control del rango dinámico a partir de una secuencia de control del rango dinámico correspondiente a la señal de audio y que comprende tramas consecutivas de control del rango dinámico, donde cada trama de control del rango dinámico de las tramas de control del rango dinámico comprende uno o más nodos, donde cada nodo de dichos uno o más nodos comprende información de ganancia correspondiente a la señal de audio e información de tiempo que indica a qué punto en el tiempo corresponde la información de ganancia; donde el codificador de control del rango dinámico está configurado de tal manera que el flujo de bits codificado para el control del rango dinámico comprende, por cada trama de control del rango dinámico de las tramas de control del rango dinámico una correspondiente porción del flujo de bits; donde el codificador de control del rango dinámico está configurado para ejecutar un procedimiento de desplazamiento, donde uno o más nodos de los nodos de una trama de control del rango dinámico de referencia de las tramas de control del rango dinámico son seleccionados como nodos desplazados, donde una representación de bits de cada uno de dichos uno o más nodos desplazados de dicha una trama de control del rango dinámico de referencia está inserta en la porción del flujo de bits correspondiente a la trama de control del rango dinámico que sigue a dicha trama de control del rango dinámico de referencia, donde una representación de bits de cada nodo restante de los nodos de dicha única trama de control del rango dinámico de referencia de las tramas de control del rango dinámico está inserta en la porción del flujo de bits correspondiente a dicha una trama de control del rango dinámico de referencia.
