You are right. I think everything should be using fixed point, because only
lamers use floating point, it's a horrible idea.
Regarding the vorbis benchmark, it sounds interesting (I would be even more
interested in how ffmpeg would have compared). It is mostly the same code
(tremor and libvorbis), so I am somewhat puzzled at the result you are
What kills me, doesn't make me stronger.
