[vorbis] New decode chip

[Oliver D. Jones]

Does anyone remember that experiment done in New Scientist, where they
had a FPGA "mutate" until it did a specific job well enough? I wonder if
something similar could be done to encode Ogg Vorbis. It might come up
with some improvements that even the cleverest hand-tuners may miss.

The easy answer: "Vorbis works smarter, not harder."

Actually, Vorbis is slower at encoding than some of the better tuned mp3

encoders, but that's mostly because it hasn't had the time to be tuned
as 
much.

I imagine that if someone wanted to fork the Vorbis encoder and give it
lots 
of hand tuning and assembly code, you could probably get some pretty
hefty 
improvements.  (For example, like GoGo derived from Lame.)
