Hi,
I found another fft algorithm in the sources (mayer-buneman with hartley transform), which I found in benchmark tests from 1993
(http://www.geocities.com/ResearchTriangle/8869/1993_fft_summary.html)
being ahead for vectors of size 64. I presume that is the one pd is using for dsp computing or am I wrong? What's the other one for? How does it compare to fftw? In another benchmark test
(http://www.fftw.org/benchfft/results/pii-300.html)
this one seems to be faster, but those tests can be deceiptive.
