Abstract

trata-se de um método para sincronizar um primeiro sinal de áudio (sa1) e um segundo sinal de áudio (sa2) que se origina a partir de um mesmo sinal de áudio original, sendo que o método compreende as etapas de: - medir um sinal de som sobreposto; realizar um tratamento do sinal de som sobreposto que compreende um cálculo de uma função de intercorrelação ou autocorrelação; estimar, a partir de um primeiro sinal tratado, um valor absoluto de um atraso de tempo (¿t) entre o primeiro sinal de áudio e o segundo sinal de áudio; modificar pelo menos uma característica do primeiro sinal de áudio ou do segundo sinal de áudio; medir, novamente, o sinal de som sobreposto; - realizar, novamente, o tratamento do sinal de som sobreposto a fim de obter um segundo sinal tratado (st2); estimar o sinal do atraso de tempo com base no segundo sinal tratado; sincronizar o primeiro sinal de áudio e o segundo sinal de áudio.
