Create Sound Synchronization Magic in Flash, Part 1
Remember the speaker cabinets from the '70s, with lights that throbbed to the music? Using a powerful third-party utility for Flash, you can create games and animations that use rapid audio synchronization to drive assets with sound instead of programming.

or basic sound synchronization needs, Flash offers two sound settings that give its users a choice in how to match audio and graphics sequences. "Event" sounds are triggered when the Flash playback head comes in contact with a frame in which the sound is placed. This is useful for short sounds and simple sound effects, for example a ball bounce sound placed in the frame where a bouncing ball hits the floor. Event sounds must be fully loaded before they can play. "Stream" sounds allow Flash to synchronize sound more like video software. When an animation soundtrack is set to stream, Flash will drop frames to keep the animation in sync with the sound. Stream sounds, as the name implies, can also play during download.
These options offer fine ways of handling sounds when basic running synchronization is needed, but what about situations requiring more control over audio sync? For example, what if you want to use programming to synchronize sound with animation such as syncing a voice-over presentation with accompanying visuals, using ActionScript instead of the timeline.
