Package: wnpp Severity: wishlist Package Name: djbfft Version: 0.76 Upstream Author: D. J. Bernstein URL: http://cr.yp.to/djbfft.html License: Public Domain Programming Language: C 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. Paul Wise schrieb:

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.
