Double-click the desktop icon to open your preferred digital audio workstation. If you don't own such a program, download a free one such as Audacity. This is a basic sound-recording program; its mixing and editing functions are limited, but it's perfectly adequate for making a CD of your voice. Alternatively, download a free trial version of a more sophisticated program, such as Ableton Live or Cubase.
Connect a microphone. If you are using an external microphone, plug that into your computer's "Mic In" socket. If you are using an audio interface, connect it to your computer either with a USB cable or firewire cable, depending on the make and model. Then connect the microphone to the "XLR Input" jack on the front. Audio interfaces allow you to connect studio-quality microphones to your computer. If you're using a built-in, there's no need to connect anything.
Test the microphone input level. Sing into it and observe the volume units meter on-screen. This is the light display that responds to an audio signal. The light display will flash red if the input level is too high. If the microphone level is too high, it will cause distortion when sound is recorded. Turn down the "Gain" dial on the audio interface to reduce the input level. If you are using a computer or built-in microphone, reduce the input level by moving away from the mic. Aim for the loudest possible input level that doesn't make the volume units meter flash red. Experiment with proximity or gain levels to achieve this.
Click "Record" and deliver a 10-second take. Press "Stop" to finish recording.
Play the recording back to make sure your voice is audible with these settings.
Hit "Record" and deliver your vocal take. If you are using backing music, connect a pair of headphones to the "Headphones" socket on your computer. This stops the backing music from spilling into the microphone during recording.
Click "Stop" when you're done recording.
Click "Play" to listen back to your recording. Check for mistakes. If you find any, record another pass.
Open the "File" menu and select the "Export" or "Export As" option. Select your preferred file type and save to your desktop.
Right-click the desktop icon and select "Open With." Select your preferred music program, such as iTunes or Windows Media Play. This launches the selected program.
Insert a blank CD into the CD drawer.
Click "File" and select "Burn Disc." To burn a disc in iTunes, first click the "+" icon to create a new playlist, then drag the song into the playlist folder. Then click "Burn Disc."
