We are about to switch to a new forum software. Until then we have removed the registration on this forum.
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)
Suggestion: Post your code so we can see what you've done so far.
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().
