Get spectrum via Fast Fourier Transformation

Real audio signal cannot be represented with simple lists, like it was with MIDI input and note-on / note-off.

The idea will be to use the Fast Fourier Transformation (FFT) in order to have the spectrum of our signal with a determined sample rate.

jMax provides a FFT object, which will allow us to get directly real and imaginary part of the FFT as input for our system. Input flow will no longer be the played signal but the spectrum of this signal.
