That's definitely cool, but from what I can see on this FAQ I do need to pay
if I'm willing to use it for commercial purposes:

Btw, have you benchmarked speex with this and without this optimization
as a hole and how much percents do you achieve? I assume FFT is a big
portion of Speex's CPU load, but it would be great to see numbers. :)
