Operating Basics
You can launch the Setup Wizard from the Control Panel to help you to
automatically set proper microphone input volumes and ensure that your
voice input(s) are working correctly. As you speak into the microphone, the
Sound Meter indicates the audio signal that your PC is receiving.
The Noise Reduction enhancement (Microphone Enhancements) helps to
eliminate ambient noise from the voice input signal to provide a clean and
clear signal to applications. This feature can be used with any microphone.

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.
For more information on using the TOSHIBA Mic Effect, refer to its help.
If the No Power Savings is selected, the audio controller always runs.
If the High Power Saving is selected, you need to play an audio file once
before you use a microphone or play an audio CD by the analog CD audio.
