How to amplify a microphone on the computer for karaoke

You can enjoy karaoke at home without a karaoke machine, by attaching a microphone to your computer and playing the output through external speakers. Windows 8 enables line-in ports automatically, but if you can't hear your singing over the backing track you may need to configure your sound settings. If you have a condenser microphone, connect it to the computer through a pre-amplifier and make sure the mic is plugged into an AC socket.

Skill level:
Moderately Easy


  1. 1

    Connect your microphone to the computer through the line-in port. Use the same port if you are connecting the microphone through a pre-amplifier.

  2. 2

    Open the Settings charm and type "Sound" into the Search box. Click "Sound" and choose the "Recording" tab.

  3. 3

    Check that your microphone is shown as the default device. If it doesn't appear in the list, right-click in an empty area of the Sound window and check "Show disabled devices" and "Show disconnected devices." Right-click on your microphone and choose "Enable."Select the microphone you want to use, choose "Set default" and click "Properties."

  4. 4

    Click the "Levels" tab. If the Muted button appears next to the microphone, click the button to un-mute it.

  5. 5

    Click and drag the slider bar to increase the volume to at least 75. If other line-in devices such as a microphone boost are available, increase the volume on those as well. Click "OK."
