Here's some shareware that I use for audio converting. It's called SoundConverter and I happened to get a free licence to it. It's free for files under 500K and costs $14 to buy. It may or may not support your file type. Even though there is a "supported file types" list, it may not be correct. I'd download the trial version and give it a try: http://download.cnet.com/SoundConverter/3000-2140_4-10184102.html?tag=vtredir
