Abstract

Un aparato para seleccionar uno de un primer algoritmo de codificación que tiene una primera característica y un segundo algoritmo de codificación que tiene una segunda característica para codificar una porción de una señal de audio para obtener una versión codificada de la porción de la señal de audio, comprende un primer estimador para estimar una primera medida de calidad para la porción de la señal de audio, que está asociada con el primer algoritmo de codificación, sin codificar y decodificar realmente la porción de la señal de audio usando el primer algoritmo de codificación. Un segundo estimador para estimar una segunda medida de calidad para la porción de la señal de audio, que está asociado con el segundo algoritmo de codificación, sin codificar y decodificar realmente la porción de la señal de audio usando el segundo algoritmo de codificación. El aparato comprende un controlador para seleccionar el primer algoritmo de codificación o el segundo algoritmo de codificación basado en una comparación entre la primera medida de calidad y la segunda medida de calidad.
