Yes, I found the soundtransform thing - thanks. Unfortunately, it doesn't include any pitching, but you can send different amounts of the signal to the left and right speakers - which I might be able to use creatively. I'm not exactly sure how to go about this though. Do I have to import the flash.media.SoundTransform and then play my sound via a code block? I'm no programmer, but if I get the syntax right, I might be able to figure it out.
Thanks for any help you can offer.
