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
suppress 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 effectively 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
(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.
