How to use FFT on array of values instead of AudioIn

ManuelRomei

How can I use a FFT on an array of sampled-values? They are values sampled at 100 Hz. Do I have to simulate an audio track and then make the FFT? How could I do it? (I am a new Processing user)

I have no idea which library you are using, but in minim you can pass a float-array instead of an AudioBuffer to functions like FFt.forward().
