Abstract

Un dispositivo para el control de volumen para al menos dos fuentes de audio incluye un analizador de intensidad y un regulador de volumen. El analizador de intensidad es configurado para analizar una señal de audio de la primera y de la segunda de dos fuentes de audio durante un periodo de tiempo, para determinar un primer y un segundo valores de intensidad, respectivamente, como función del mismo, y para almacenar los mismos asociándolos a la vez con la primera y la segunda fuente de audio. El regulador de volumen es configurado para adaptar la señal de audio a la primera y/o segunda de las dos fuentes de audio actualmente seleccionadas de acuerdo con el primer y/o segundo valores de intensidad correspondientes.
