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

computer.
To apply the echo cancellation, follow the steps below.
