Flash Animation 15: Starting and Stopping Sound Effects

Now what comes next is the tricky part. Normally when you insert audio on a Flash layer, it simply starts on load and plays continuously unless you've told it to only loop a few times; there's nothing to synch it to start and stop on a particular frame. But since we only want to play the bouncing sound effect during the frames when the actual bouncing impact is taking place, we need to use some keyframes to control our sound's stops and starts.

To do that, we'll first need to create a new layer. Mine is labeled "Sound Effects".
