description:
  This library provides a pure Haskell complex-to-complex Fast Fourier
  Transform implementation for arbitrary length input vectors, using a
  mixed-radix decimation-in-time algorithm with specialised
  straight-line code for a range of base transform sizes, Rader's
  algorithm for prime length base transforms, and an empirical
  optimisation scheme to select a good problem decomposition.
  .
  This package is probably primarily of pedagogical interest (FFTW is
  about five times faster for most input sizes).  There is a long
  series of blog articles describing the development of the package,
  indexed at <http://www.skybluetrades.net/haskell-fft-index.html>.
