  • Full description
    D.J. Bernstein Fast Fourier Transform (djbfft) is an extremely fast library for floating-point convolution. The current version holds most of the speed records for double-precision FFTs on general-purpose computers. djbfft provides power-of-2 complex FFTs, real FFTs at twice the speed, and fast multiplication of complex arrays. Single precision and double precision are equally supported.
