Kiss FFT is a small and simple FFT library. It has no complicated platform-specific optimizations, is able to do fixed or floating point with just a recompile, and is efficient enough for all but the most demanding applications.

Release Notes: This release adds various minor code cleanups related to SIMD and testing.
Release Notes: This release is focused on thread-safety. Internal static structures have been removed from the core FFT routines. This allows better thread safety with the internal OpenMP threading model and user-imposed threading.
Release Notes: This release focuses on embedded issues.
Release Notes: A slight interface change was made: a cfg object is now a forward declaration of a struct instead of a void*. Small speed improvements were made. psdpng.c was added to create PNG spectrum "waterfalls" from an input file.
Release Notes: A problem in which nfft==1 failed under certain conditions was fixed.
