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.
