Search http://freshmeat.net/ for kissfft. Its BSD licensed
and has a really nice simple interface.

One way (sometimes not the best) is to use a CAS like Maple:
let it display the code for its FFT and use build-in functions
to let it produce C code.

You can start with netlib/fftpack lib. There are many other resources as
well, just do a search with "fft" on netlib site.

check musicdsp.com, go into the archives, or just type "fft" into the 
search field, you'll find several public domain FFT implementations.

Dear all,

I was wondering whether there was any free C/C++ FFT library with a LGPL or
BSD style license, or even a propretary license. There is of course FFTW but
it is GPL and for the project that I am currently working on, I am
unfortunately unable to release the source code thus I am unable to use it.

Your help would be very much appreciated.

Many Thanks

RG
