Abstract

trata-se de um dispositivo para controle de volume para pelo menos duas fontes de áudio que inclui um analisador de altura e um regulador de volume. o analisador de altura é configurado para analisar um sinal de áudio da primeira fonte e da segunda fonte dentre as duas fontes de áudio ao longo de um período de tempo para determinar um primeiro e um segundo valores de altura, respectivamente, como uma função do mesmo e para armazenar os mesmos enquanto associa os mesmos à primeira e à segunda fontes de áudio. o regulador de volume é configurado para adaptar o sinal de áudio da primeira e/ou da segunda fonte atualmente selecionada dentre as duas fontes de áudio de acordo com o primeiro e/ou o segundo valor de altura correspondente.
