Back in the Properties Inspector, the final set of options involve syncing and looping your sound. The first of the two options is Sync, which controls how your sound file will play in the Flash document. Here are the syncing choices:
When you are deciding which of these options to use, make sure you test the movie to listen to the sound, because these options can sometimes have an effect on the quality of the sound itself.
After syncing, you can choose from the looping options. Looping is the best way to make a short sound loop appear longer than it actually is. Because the longer the original sound file is, the more file size it will create, looping is a great alternative to longer tracks. The two options for looping are the following:
After you set a looping preference greater than 1, the Edit Envelope window for the Effect option will look something like Figure 6.6.

That concludes editing the sound as far as syncing and effects are concerned, but you can also edit the compression of the sound file itself from the library.
