TOSHIBA Mic Effect
TOSHIBA Mic Effect provides you with a hands-free environment for
holding mutual communication via the Internet Protocol or Local Area
Network. If you wish to communicate with someone on your computer, you
can use a messenger application. However, with such an application, you
would hear your own voice returning to you as echo during the
communication if you did not use a headset system or headphone.
TOSHIBA Mic Effect will reduce these echoes generated on your computer.
To apply the echo cancellation, follow the steps below.
1. Click the right button of a mouse on the speaker icon on the Taskbar,
and select Playback Devices in the sub menu.
2. On the Playback tab, select Speakers, and click Properties.
3. On the Advanced tab, select "16 bit, 48000 Hz (DVD Quality)" in the
pull-down menu of Default Format, and then click OK.
