Audio Smileys is a cute little application that allows you to play funny sounds to express your feelings. It is mostly targeted for youngsters, but of course, anyone can use it for fooling around with friends, or pulling pranks at co-workers. Once launched, just press keys 1...9 on your keypad to play the sound. In addition, you can create your own audio smileys with the built-in audio smiley editor.
