What is FFT library?

Introduction. FFTW is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions, of arbitrary input size, and of both real and complex data (as well as of even/odd data, i.e. the discrete cosine/sine transforms or DCT/DST).

What is the most common library for FFT?

FFTW is the most popular FFT library. It has planty of features and it's often used as the reference point, but a number of other libraries has comparable or better performance.

What is kiss FFT?

A Fast Fourier Transform based up on the principle, "Keep It Simple, Stupid". Kiss FFT is a very small, reasonably efficient, mixed radix FFT library that can use either fixed or floating point data types. Header files and static library are provided. (

What is kissfft?

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