Abstract

Se proporciona un aparato para analizar un espectrograma de magnitud de una señal de audio. El aparato comprende un determinador de cambio de frecuencia (110) que es configurado para determinar un cambio de una frecuencia por cada compartimiento de tiempo-frecuencia de una pluralidad de compartimientos de tiempo-frecuencia del espectrograma de magnitud de la señal de audio. Además, el aparato comprende un clasificador (120) que es configurado para asignar cada compartimiento de tiempo-frecuencia de la pluralidad de compartimientos de tiempo-frecuencia a un grupo componente de señal de dos o más grupos de componente de señal dependiendo del cambio de la frecuencia determinada por el compartimiento de tiempo-frecuencia.
