vorbisfile interleaves the output samples as the final step before 
returning them to the user. Obviously you could de-interleave them,
but that's not terribly efficient. Perhaps in your case you'd be 
better off using libvorbis directly after all. However, then you need
to calculate the number of samples in the file yourself, which is a 
pain to do unless you ignore the possibility of chained streams.
