No problem. You're welcome.

I don't think there is an official spec for how tag fields should be set within a WAV, but the way AudioGrabber is adding them shouldn't cause a problem when trying to use that WAV elsewhere. I believe the WAV spec does allow metadata of some form to exist. There's info about this on the AG site somewhere or in the AG help file. It would be nice if this info were able to be used by other software. And it would be nice if other software (rippers) also tagged their WAVs in the same way (making interoperability a lot easier - a lot of people have a hard time doing smooth/simple tagging as part of their workflow)
