Installing Drivers and Software

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 benet with less echo.
