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 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 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.
