Actually, no. IMO determining the file type by the use of magic
numbers is preferable.

Actually it is RIFF that wraps WAV.

However, take another look at that hexdump. The 'RIFF' chunk enclosed a
'WAVE' chunk and then the Ogg data is contained inside the 'data' chunk.

Personally I think that is dodgy; a typical hack on top of a bodge etc.
