Hi all, (A bunch of stuff on FFTs)
Has anyone done any speed comparisons between
- the FHT based code lame has now (which is damn fine)
- "fastest fourier transform in the west" fftw (www.fftw.org)
- pentium optimized fft - djbfft http://pobox.com/~djb/djbfft.html
(gives out-of-order output,that i'm not too sure how to grok)
I like the fht-based one that's there at the moment because its
general, self-contained and works fine on well on most architectures (afaik).
If you dip into comp.dsp you'll see a lot of "talk" about djbfft and
fftw and comparisons and "benchmarks"
The FFTW have announced a pentium optimized FFTW library. Only does
complex input though.
later
mike
