opus - Feb 2014 - about optimization

Hi All,

We have some optimizations for x86-64 and SSE enabled CPU since encoding Opus
stream on server side is time sensitive.
The optimization is based on opus-1.0.3, and after 1.1 is released we have to
merge the changes.

The question is can we share back the optimizations to Opus repository? If yes,
how can I do?

Thanks,
XM

Great, we definitely welcome contributions. You can post patches here on
the list for review, or if there are a lot of them I can make you an
account on https://review.xiph.org/ and you can upload them there.

Have you already rebased your changes onto 1.1? There were some
significant C-level optimizations between 1.0.3 and 1.1.

Not only that, but there's been significant changes in git since 1.1,
especially in the MDCT/FFT.
