Is there an official specification regarding how Replay Gain information is meant to be stored in Vorbis Comments? All Vorbis Comment related documents that I could find don't mention any details. I'm surprised that I can't find anything relevant since software supporting Replay Gain for Vorbis has been around for some 8 years now if not longer.
Disclaimer: I know how it works, I'm just looking for a reference document that I can show to someone else.
