Microphone
In this tab you may set the function of the microphone. Select the Noise Suppres-
sion to remove the possible noise during recording, or select Acoustic Echo
Cancelltion to cancel the acoustic echo druing recording.
Acoustic Echo Cancelltion prevents playback sound from being recorded by mi-
crophone together with your sound. For example, you might have chance to use
VOIP function through Internet with your friends. The voice of your friend will come
out from speakers (playback). However, the voice of your friend might also be
recorded into your microphone then go back to your friend through Internet. In that
case, your friend will hear his/her own voice again. With AEC(Acoustic Echo
Cancellation) enabled at your side, your friend can enjoy the benefit with less echo.
