When you visit a full-fledged Flash Web site, sound is almost always present. Some sites greet you with background music, and other sites have buttons that make noises when you click them. Sound used with discretion is a useful addition to any Flash project. In this minibook, we show you how to incorporate sound into you projects. We discuss the supported sound formats and then show you how to sync sound to your projects and create noisy buttons to optimize your joyful noises for Flash. We also show you how to use ActionScript to load external sound files into a project.
