how to do inverse fourier transform?

beginners
#1

There is something in opeframework similar to “fft.inverse” de minim in processing

#2

Hi, it seems like fftw (a C library) provides inverse fft.

ofxFft is a wrapper around fftw. I see executeIfft() there.

#3

ofxMaxim can do it rather well. I did a few things with it last year, ask me if you need help!

#4

Ah right! I checked the ofxMaxim examples but didn’t see any for inverse FFT. Now I see it has both maxiFFT and maxiIFFT classes.

Yeah, the documentation for ofxMaxim is not very thorough, but there are lots of hidden things in the library and it’s a very powerful library indeed if one is willing to go and peek into the behind the scenes.
