How to Record a Sound on a Windows Computer. You can use the Windows Sound Recorder to record your own warning beeps or other sounds. You'll need a sound card that supports sound input, a microphone and speakers.
If your computer has a sound card and speakers, as most do, you will only need to acquire a microphone (fewer computers come with them). Microphones range in price greatly; if you're just recording simple sounds and effects, buy a cheaper microphone.

Attach your microphone to the Sound In port on the back of your computer. (It might have a picture of a microphone next to it.)
If your microphone has an On button, turn it on. Otherwise, refer to the instruction sheet that came with it.
Open the Sound Recorder. (Open the Start menu and choose Programs, then Accessories, Entertainment and, finally, Sound Recorder.)
From the Sound Recorder, click New.
To begin recording, click Record - the circle that appears at the right-hand side of the Sound Recorder.
When you are finished recording, click Stop - the square that appears directly to the left of the circle.
Use the Play, Rewind and Seek to End buttons to test your recording.
When you are satisfied, save your sound file using the Save As command in the File menu.
Things You'll Need
You can also record from a CD player, if you have one. Sophisticated software is available for purchase if you want to perform more complex tasks with sound. The Windows Sound Recorder is very basic.
Sound files are very large and will take up considerable space on your hard disk.
