Puzzled by the claim that the Ooura FFT seems to be faster, or as fast
as the FFTW package, I looked for benchmarks on Internet, and found the
following page (and others related)<br>
<br>
<a class="moz-txt-link-freetext" href="http://www.fftw.org/speed/opteron-2.2GHz-32bit/">http://www.fftw.org/speed/opteron-2.2GHz-32bit/</a><br>
<br>
<br>
The graph on that page is here below. Admittedly, the measures were
performed by the FFTW team, but I think they are honest and unbiased
persons.<br>
For a 1024 points transform, the FFTW seems to 1.3 times faster than
Ooura's. The platform was Linux. Maybe on the .NET the situation is
reversed...<br>
