Why is it rubbish? The project wanted a vorbis encoder, the project got a
vorbis encoder. IMHO it is as good as a lossy encoder without a psychoacustic
model can be (mind you, I didn't write the vorbis encoder, Oded did).

Yes, those words were also mostly true about my sparc idct, but it was not
acceptable. Btw I agree with you, and it is good you comitted your idct.

Well I am sure arm users (and there are some) will be glad if you revisit
