Looping is set in the sound dialogue, which is a tab in frame properties.

That's where you set the number of loops, and can edit (although crudely)

the portion of the sound that's actually played. Do not attempt to loop the

sound by placing several instances of the sound in the timeline, Flash just

does not synchronize that way.


To make a sound loop smoothly, you have to start with a sample whose end

blends seamlessly into the beginning. Unless you acquire a sound that was

designed to loop, you need a sound editor to do this well, one that lets

you playback in loop mode while you make precision cuts at either end of

the sample. Otherwise you'll have a noticeable silence or pop at the end of

every loop. It's also possible that by having two sounds of different

lengths looping at the same time, you can camouflage the pops or silences.

Really though you need sound editing software.


I work on PC, but SndSampler 3.6, available at

http://hyperarchive.lcs.mit.edu/HyperArchive/Archive/gst/snd/snd-sampler.hqx

, has been recommended to me as a very inexpensive Mac-based sound editor

with loop-point editing options.
