Presentation audio help

hey, looking for a little advice on how to treat the audio for a presentation i’m doing in flash for a client. they want it to run like this arbonne international’s presentation.

the audio is pretty much seemless from slide to slide and there isn’t any preloading at all.

i’ve got 19 individual pieces of audio that i need to play when the apropriate slide is viewed, but i don’t want a huge preload in the beginning or preloaders for each slide.

i’ve compressed the audio about as low as i’m going to get it before it’s not listenable.

any suggestions? should i leave the audio in the library and load it with AS? that seems to be the only way to get around a long preload in the intro.

thanks. haam.
