Abstract

Un evaluador de similitud de audio obtiene señales de envolvente para una pluralidad de rangos de frecuencia con base en una señal de audio de entrada. El evaluador de similitud de audio está configurado para obtener una información de modulación asociada con las señales de envolvente para una pluralidad de rangos de frecuencia de modulación, en donde la información de modulación describe la modulación de las señales de envolvente. El evaluador de similitud de audio está configurado para comparar la información de modulación obtenida con una información de modulación de referencia asociada con una señal de audio de referencia, con el fin de obtener una información acerca de una similitud entre la señal de audio de entrada y la señal de audio de referencia. Un codificador de audio utiliza tal evaluador de similitud de audio. Otro evaluador de similitud de audio utiliza una red neuronal entrenada utilizando el evaluador de similitud de audio.
