Abstract

um método para executar a redução de ruído inclui a captura de um primeiro sinal de áudio em um primeiro microfone de um primeiro dispositivo. o método também inclui a recepção, no primeiro dispositivo, de dados de áudio representativos de um segundo sinal de áudio de um segundo dispositivo. o segundo sinal de áudio é capturado por um segundo microfone do segundo dispositivo. o método inclui ainda a realização de redução de ruído no primeiro sinal de áudio com base, pelo menos em parte, nos dados de áudio representativos do segundo sinal de áudio.
