Sound Forge and Wavelab can open "raw" files.

As can Adobe Audition (ne. Syntrillium CoolEdit)

If your files aren't truly corrupted you can assign
the correct parameters to the raw file and save as
wav or whatever format you need.

Maybe there are some freeware or shareware programs that
will do the same thing. I don't think Audacity can do it.

If it is worth the effort(?), one could even construct your
own headers with a hex editor.
