djbfft - Extremely fast library for floating-point convolution
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.
