You need microphone to do this. This program show how loud are your voice. It gives waves of voice. CONTROL -- Press record to record voice. When you are done. Press record until red lettering is gone. Then press play to see wave of your recorded voice. Press play again until red color is gone. Green Line = Recording or Free Time. Clear to delete your recorded voice. Ramdom Color = Waves of Recorded Voice I made it all by myself. In program it's messed up, you would have hard time to remixing this. Have a fun. Comment if you like it.
