Using the microphone
Your computer has a built-in microphone that can be used to record
monaural sounds into your applications. It can also be used to issue voice
commands to applications that support such functions.
Since your computer has a built-in 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.
To adjust the volume or activate Mute in Windows 95/NT, click the Start
button, point to Programs, point to Accessories, point to Multimedia
and click Volume Control.
In Windows 98, click the Start button, point to Settings, and click
Control
Panel. Next, double-click the Multimedia icon, then select the
Audio
tab and double-click the icon in the Playback group to open the
Volume Control
panel.
In the Volume Control panel, you can use the Microphone Volume slide
bars to adjust the volume level or click Mute at the bottom of the panel.
