DJ Booth would have worked as well, but this fits too.
On topic:
WAV files are bit more limited, imho, when it comes to tagging than MP3’s for example.
You should be able to do this stuff in Explorer (Windows) or Finder (OSX) though. Just make sure you select the right columns to show and then just edit the fields. It can also be done in MP3 tagging progs.
There is a difference between tag info and CD Text though. The latter is what your CD player (in the car for example) shows as album, artist, track info. Never bothered to work it out exactly, but I know that for some tracks that I had tagged correctly, when I burned them to CD that info was suddenly lacking from the audio CD. Could be something in the burning software though.
