Introduction to Realtek ALC 880
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
microphone 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. W ith AEC(Acoustic Echo
Cancellation) enabled at your side, your friend can enjoy the benefit with less echo.
Also, please use the drop-down list to choose the recording source from Realtek
HD Audio real input or Realtek HD Audio front input.
