Abstract

"PROCESSO DE GERAR UM SOM DE SAíDA DE áUDIO A PARTIR DE UM DISPOSITIVO DE COMUNICAçãO ELETRôNICO, E, DISPOSITIVO DE COMUNICAçãO ELETRôNICO". A geração de um som de saída de áudio de um dispositivo de comunicação eletrônico inclui a monitoração de um nível de um suprimento de potência elétrica e o ajuste de um sinal de entrada de áudio responsivo às mudanças do nível do suprimento de potência elétrica para o dispositivo de comunicação eletrônico. O sinal de entrada de áudio ajustado é amplificado e um som de saída gerado responsivo ao sinal de entrada de áudio ajustado e amplificado. Além disso, um sinal de saída de áudio pode ser gerado responsivo ao som recebido, incluindo um eco do som de saída, uma estimativa do eco do som de saída pode ser gerada, usando o sinal de entrada de áudio ajustado e um modelo de um caminho de eco do som de saída e a porção de eco do sinal de saída de áudio pode ser reduzido, usando essa estimativa.
