使用其他的麦克风
您可以使用外部麦克风进行音频会议，制作音频文件，或者使用其他多媒体应用程序。即使您的计算机有内置麦克风或带有麦克风的网络摄像头，但是单独的麦克风可提供更出色的音质。
If your microphone has a circular plug, just plug it into the appropriate audio socket on your computer. Most computers have two sockets: one for microphones and one for speakers. This socket is usually light red in color or is accompanied by a picture of a microphone. Microphones plugged into the appropriate socket are usually used by default. If not, see the instructions below for selecting a default input device.
如果您使用 USB 麦克风，把它插入任何一个 USB 接口。USB音箱将作为单独的音频设备，您可能要指定默认使用哪一个麦克风。
选择默认音频输入设备
Go to the Desktop and start typing Sound.
Click on Sound to open the panel.
In the Input tab, select the device that you want to use. The input level indicator should respond when you speak.
You can adjust the volume and switch the microphone off from this panel.
