Microsoft Windows (all versions) has a built-in feature called the Sound Recorder. You can use this program to create sound files that can be used in your computer’s sound scheme or that you can send to people via email. The sound files can be up to 1 minute in length and save in the WAV format. You can even add a few neat effects, like Echo and Reverse, or change the speed of the sound.
To access the Sound Recorder, click the Start button and click All Programs (Programs in Windows versions older than XP). Go to the Accessories menu item and click Entertainment. The Sound Recorder program should be the first program on the list.
