Maybe this could be useful for Cliff

I have no idea what that stuff means, but damn it looks cool. Who knows what kind of breakthroughs that'll lead to with tech in the decades ahead?
 
That could be useful for the kind of stuff we do someday.

The CZT is a generalization of the FFT. The FFT samples the unit circle at uniform intervals. The CZT can sample the z-plane along spiral contours.

In general, however, the FFT is faster than any of the fast CZT transforms and an inverse CZT transform is likely to be very slow.
