Abstract
Las formas de realización se refieren a una unidad de procesamiento de audio que incluye un búfer, deformateador de carga útil de corrientes de bits, y un subsistema de decodificación. El búfer almacena por lo menos un bloque de una corriente de bits de audio codificada. El bloque incluye un elemento de relleno que comienza con un identificador, seguido de datos de relleno. Los datos de relleno incluyen por lo menos una bandera que identifica si debe realizarse el procesamiento de replicación de banda espectral mejorada (eSBR) sobre contenido de audio del bloque. Se proporciona además un método correspondiente para la decodificación de una corriente de bits de audio codificada.
