Reading Monty's message, I better re-post this one :-).

In another thread the following was said:

Speaking of which, would there be anything to stop Vorbis, maybe not v1 
but in the future, to use similar techniques as the ones emplyoed by 
mp3pro and the similar thing for aac? I am refering to the spectrum 
duplication.. even though it sounds a bit weird to me, that it can work 
well in all circumstances; but mp3pro does sound significantly better 
than regular mp3.
