DUE's more advanced FFT capabilities

raalst:
Nope, I was happy with whatever I could get to work, since I'm still at the
"thinking about it" phase of my project.
I have not really made an effort specifically for the Q31.
It might be hard, it could be simple ....

It is not hard, I have it for Q15, the problem is, if I use any Q31 array, arduino just freezes!!
