If they were using a Mac, it's possible that they recorded the audio as SD2 files, which a PC can't read (even though as I understand it, they are very similar to WAV files except for the header.)
You might try the following:
1) Try renaming the files and adding a ".wav" or ".aif" extension to them. You might luck out if they are indeed WAV or AIFF files.
2) You'll need to find a Mac and an audio converter program such as Cleaner to convert the files into WAVs or AIFFs. Alternatively, if you could find a Mac with Pro Tools on it, I believe you can select and export the files from Pro Tools into another format.
I could be forgetting some things, but those are the first two that came to mind. Mac doesn't really care about extensions, so you might try copying them to a hard drive and trying option #1 first. Love to know how you solve it when you do.
