Have any of you guys found a good FFT library besides FFTW that fits the following: 1) handles any size input array, i.e. not only powers of two 2) computes real to complex 3) free with source code 4) C/C++ I have yet to find a single library that matches all three besides FFTW. Unfortunately, I'm having a HELL of a time getting FFTW to work right. I don't want to have to run my program using the fftw3.dll...I would like to incorporate the entire library into my final .exe but it's turning into a nightmare. Thanks.
