Abstract

La presente invención es concerniente con el volumen percibido de una señal de audio que es medido al modificar una representación espectral de una señal de audio como función de una forma espectral de referencia, de tal manera que la representación espectral de la señal de audio se conforma más estrechamente a la forma espectral de referencia y determinar el volumen percibido de la representación espectral modificada de la señal de audio.
