(Ooops, meant to reply on-list. Alex got back to say the files are packaged
with the app, so what I've said below isn't the full answer, may be another
issue.)

I've no experience with it, but it looks like fopen is a non-starter:

This will break SO much. Still libvorbis doesn't care about the data
reading mechanism as long as you can get the data for it. If you're using
libvorbisfile you'll need to use the callbacks API, <
