  <title>使用其他的麦克风</title>

  <p>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。</p>

  <p>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.</p>

  <p>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。</p>
