Verify that you have a sound card installed on your PC by navigating to "Run," then typing "devmgmt.msc" (without the parentheses). Click "OK." The "Device Manager" task-bar opens. If a sound card is present, it is listed under the "Sound, Video, & Game Controllers" section. If you don't see a sound card listed, you must install one.
Open an audio-recording application, such as Garage Band or Audacity. You can download Garage Band and Audacity for free.
Plug your microphone into the “Input” connection of your computer. For best vocal sounds, use a cardioid condenser microphone. You can connect many cardioid condenser microphones via a USB cable instead of the “Input” connector. As of July 2010, the starting price of a good cardioid condenser microphone costs between $80 and $100.
Place a “Pop Filter” in front of the microphone to prevent hissing and popping sounds as your record your vocals. Position the pop filter so that it is three to four inches away from your mouth.
Ensure that there is no background noise that you do not want in your recording.
Click the “Record” button on the audio-recording software.
Start speaking into the microphone to record your voice. Generally, you will see the equalizer bar moving to indicate that your sound is being captured.
Press the “Pause” button to pause recording. Press “Pause” again to resume where you left off. Press the “Stop” button when your recording is complete.
Navigate to “File” and click on “Save As” to save your audio file.
Edit your microphone vocals to ensure that it sounds the way you desire. If you are using “Audacity,” you can click on the “Effects” option from the top menu bar to change the pitch of your recording, change the tempo, change the bass level, remove background noise, fade out/fade in the sound and add sound effects.
