I knew every note of [Karn Evil 9] and could hear the sweeping filters and the fundamental wave shapes underneath ... scope in the form of a Fast Fourier Transform (FFT). For this demonstration ...

The representation of a PERIODIC sound or WAVEFORM as a sum of Fourier components (i.e. pure SINUSOIDAL WAVEs). According to the FOURIER THEOREM, periodic sound may be shown to consist of SINE WAVEs ...

That may be splitting hairs, but it is worth nothing that SciPy (pronounced “Sigh Pie”) also does other handy tricks like Fourier transforms ... For example, sine waves can be generally ...
