djbfft is an extremely fast library for floating-point convolution.
The current version holds most of the speed records for
double-precision FFTs on general-purpose computers.
.
djbfft provides power-of-2 complex FFTs, real FFTs at twice the
speed, and fast multiplication of complex arrays. Single precision
and double precision are equally supported.

I've never heard of this before, too. However, the source code can be
found at <http://cr.yp.to/djbfft.html>
It is Copyright 1999, D. J. Bernstein but does not contain a license. I
doubt that it is suitable (or even useful) for Debian.
DJB has since placed all his future and past software in the public
domain. Perhaps ping him if you need clarification of this.
