Microphone
This page is designed to provide you better microphone / recording quality.
Below picture indicates both “Noise Suppression” & “Acoustic Echo Cancella-
tion” 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.
