Description FFTW is a free collection of fast C routines for computing the Discrete Fourier Transform in one or more dimensions. It includes complex, real, symmetric, and parallel transforms, and can handle arbitrary array sizes efficiently. FFTW is typically faster than other publically-available FFT implementations, and is even competitive with vendor-tuned libraries. (See our web page for extensive benchmarks.) To achieve this performance, FFTW uses novel code-generation and runtime self-optimization techniques (along with many other tricks).

For a quick introduction to calling FFTW, see the "Tutorial" section of the manual.


This is a 64-bit build that should run on any x86_64-Family CPU, in any 64-bit OS. SSE/SSE2 are automatically used *when available* (Pentium III/4 or newer).

Both static and dynamic (DLL) libraries are included.

Threading is enabled.

Libraries passed all built-in tests.

The latest documentation is included in Compiled-HTML (CHM) and PDF formats.
