So you wouldn't be able to directly share with us coding tips or source
code? Technical advice only?
I assume you didn't get a 'cease and desist' letter from FhG then?

Where did you get the technical knowledge to do this? are you a
compsci/dsp person? or are you just very good at reading the cryptic ISO
documents.

ugh.
Admittedly, I've never looked at the acuracy of the routines in comparison
to the standard. I'd sort of assumed they were right, and spent time just
speeding them up.
The code is pretty fast now and the focus should shift towards improving
the quality.

cool. Get out your ISO documents folks, it's time to start reading :)
