I had talked earlier with 'Timothy B. Terriberry' <tterribe at xiph.org>, about adding support for AVX instructions in Opus, but since he appears to be busy I would like to resend this on the mailing list.
I've created a pull request https://github.com/xiph/opus/pull/5 to add the testing infrastructure for the changes before adding the actual code.

A draft for the rest of the code for the AVX functions can be found here: https://github.com/rvelea/opus/commits/workspace. Timothy advised me to break them into smaller commits before trying to push them so as not to break anything.

If anyone is interested in reviewing this please let me know and I will follow up with the rest of the code via pull requests.
