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 filtro configurado para recibir la señal de audio, para reducir la amplitud de armónicos en la señal de audio y para producir una versión filtrada de la señal de audio. Se proporciona un primer estimador para usar la versión filtrada de la señal de audio en la estimación de una SNR o una SNR segmentada de la porción de la señal de audio como 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. Se proporciona un segundo estimador para estimar una SNR o una SNR segmentada como una segunda medición de calidad para la porción de la señal de audio, que está asociada 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 en base a una comparación entre la primera medición de calidad y la segunda medición de calidad.
