Microphone
This page is designed to provide you better microphone / recording quality.
Below picture indicates both “Noise Suppression” & “Acoustic Echo
Cancellation” are both enabled.
Noise Suppression
If you feel that the background noise, especially the sound generated from the fan
inside PC, is too loud? Try “Noise Suppression”, which allows you to cut off and sup-
press disturbing noise.
Beam Forming
Also known as “directional recording”, this option lets you do the following: Once beam
forming is enabled; only the sound from certain direction will be recorded. You will get
the best quality if you chose 90° position, which we recommend you to use, this ef-
fectively means that you speak right into the microphone.
Note: A Stereo Microphone is required when using Beam Forming function.
Acoustic Echo Cancellation
This function 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 (play-
back). 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.
