    5252FFTW contains deep magic, and is comparable with vendor optimised versions. "Estimate" mode is not the most magical. The "Measure" mode of FFTW performs runtime profiling to determine the best way to do an FFT on your hardware. However, this process can require several seconds of startup time, which is why I haven't enabled it.

    54 The FFTW version uses a precomputed wavetable of sin and cos values, but the others (including Jones's) do not.
