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. W ith AEC(Acoustic Echo
Cancellation) enabled at your side, your friend can enjoy the benefit with less echo.
