Herman, Michael's right--there are some fields in wav files that can be used for tag data. But, it is completely nonstandard and won't translate.
Michael, not sure whether you are on a Mac or PC platform. I'm guessing Mac, since you mentioned Aperture.
If you are on a Mac, you may be able to import some data into iTunes. Google "doug's applescripts"... You should be able to find one that will at least create iT tags for Artist/Album/Song from the directory structure (you do have them organized in an Artist/Album/Song structure, I hope).
If you are on the PC side, look into Foobar. Its ugly out of the box, but there is a pretty good tutorial on www.lifehacker.com on how to customize it and make it pretty. One of Foobar's features is masstagger, which will allow you to write a little script to do the same kind of thing I mentioned that Applescripting can do.
