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.

4.On the Recording tab, select Microphone, and click Properties.

5.On the Advanced tab, select “2 channel, 16 bit, 48000 Hz (DVD Quality)” in the pull-down menu of the Default Format pane.

6.On the Enhancements tab, select the Acoustic Echo Cancellation check box, and click Apply.

Notes on Using Microphone

You can use the built-in or an external microphone that connects to the microphone jack to record monaural sounds into your applications. It can also be used to issue voice commands to applications that support such functions (built-in microphone is provided with some models).

Since your computer has a microphone and speaker, "feedback" may be heard under certain conditions. Feedback occurs when sound from the speaker is picked up in the microphone and amplified back to the speaker, which amplifies it again to the microphone.

This feedback occurs repeatedly and causes a very loud, high-pitched noise. It is a common phenomenon that occurs in any sound system when the microphone input is output to the speaker (throughput) and the speaker volume is too loud or too close to the microphone. You can control throughput by adjusting the volume of your speaker or through the Mute function in the Master Volume panel. Refer to your Windows documentation for details on using the Master Volume panel.
