Embedding Sound with Flash, Part II: Playing Variations

Event vs. Start Sync

With start sync, Flash can play only a single copy of the same sound at the same time. Start sync tracks cannot overlap each other. There are two ways to re-trigger a start sync track. You either let it play till its end and then start it again, or you can stop it with a stop label command.

The following three links demonstrate event sync tracks. Mouse over the left one to listen to a scale sound. Mouse over it again and again to re-trigger as many instances as you want. Do the same for the middle link. Since it's a looping sound, you'll get an amplification of the sound as you mouse more times over the link. Use the right link to stop the sound:

Play a Scale    Start a Looping Sound    Stop a Looping Sound

The following three links are of the start sync type. You can play each instance only once. To re-trigger an instance, you need to wait until its end, or you can stop it with the right link:

Play a Scale    Start a Looping Sound    Stop a Looping Sound
