FFTW in delphi?

Hi,

Have anybody used FFTW library in Delphi (as DLL or other way)?
I need FFT delphi algorithm for signals which size is not power of 2.
I found FFTW in internet but i can't use it.

Thanks for any help

Try out the FFT units at http://www.aho.ch/fft. It is not FFTW
but it works for signal signals with a lenght that is not a
power of 2. Source is available at a small fee.

It would be nice thought if somebody got FFTW to work with Delphi....

have a look at some of the resources listed here...

in particular, John Herbster's implementation of the Glassman FFT handles
input data of arbitrary length
