FFTW.jl
Julia bindings to the FFTW library for fast Fourier transforms
...Note that this choice will be recorded for the current project, and other projects that wish to use MKL for FFTs should also set that same preference. Note further that MKL provides only a subset of the functionality provided by FFTW. -

FFTW++ is a C++ header class for the FFTW Fast Fourier Transform library that automates memory allocation, alignment, planning, wisdom, and communication on both serial and parallel (OpenMP/MPI) architectures. In 2D and 3D, hybrid dealiasing of convolutions substantially reduces memory usage and computation time. Wrappers for C, Python, and Fortran are included.

FFTW_Ada
An Ada 2012 binding to the FFTW fast Fourier transform library
FFTW_Ada is an Ada binding to the FFTW (fast Fourier transform) library written at MIT by Matteo Frigo and Steven G. Johnson. FFTW is written in C. FFTW_Ada allows calls to FFTW from an Ada program, thus allowing Ada code to compute fast Fourier and certain other related transforms. FFTW_Ada v2 works with FFTW v3 and requires Ada 2012. -

DarkF
DarkF is an FFT optical simulation code for GW inteferometers
DarkF is an optical simulation code in FORTRAN 90 able to represent with a high accuracy any kind of stable cavity, even when many static or dynamical defects are present, like misalignments, curvature errors, surface irregularities, substrate inhomogeneities. It uses a plane wave decomposition to propagate the wavefronts. Beams and mirrors are sampled on a grid of coordinates (x; y) and the DarkF resolution is depending on the grid size and on the sampling rate (typically a size of 0.6m... -

Command line FFT
A simple command line utility to produce an FFT/IFFT of ASCII data
Ever had a bunch of ASCII data that you would like to have a quick look at in frequency domain, but don't want to fire up some bulky analysis software package just for that? Well, I have... So I wrote this tiny tool. It is based on fftw (www.fftw.org) and boost's program options (boost.org). cli-fft is really simple: All it does is to receive ASCII data from a file or standard in, FFT it and write out the result into a file or to standard out. -

FFTL
Templated Fast Fourier Transform in C++
...This is currently still a work in progress, but the FFT portion (complex and real) both output the correct results, and the code executes very quickly, around only 30% or so slower than the much more difficult to compile FFTW on SSE enabled platforms. Though optimized code only runs on SSE (x86) based platforms, it's a very simple matter to port the existing code to any other platform with different SIMD intrinsics by simply implementing a small number of inlines that map to a small number of intrinsics. The algorithm currently used is Radix-2, so there's easily room for speed improvements. -

pyL1min
General purpose norm-1 minimization solver in Python
pyL1min is a general purpose norm-1 (l1) minimization solver written in Python. It is based on NumPy/SciPy, CVXOPT ( FFTW enabled) to solve l1 minimization problems that are based on interior point methods. You need to install Python, NumPy/SciPy and CVXOPT ( FFTW enabled) to use this software. The test.py program demonstrates a simple application in Compressive Sensing and shows how to use l1min module. You need to install matplotlib to plot diagrams. -

hsfft
FFT and Convolution in C
...Only 1D , unit-stride implementation for singe core processors available as of now. USAGE HSFFT is designed specifically to handle time series data efficiently. The software is structured very similarly to available open source softwares like FFTW and kissfft. The data structure is almost identical to Mark Borgerding's kissfft implementaion. However, this implementation is lightweight compared to FFTW and should give better performance for non-power of two implementations compared to kissfft in a single core setting. The project is a work in progress and the To-Do list is considerably long, including an implementation with multicore/multithread support, real FFT support, multi-stride and multi-dimensional FFTs. ... -
