Unlike the Amiga which requires an external 8-bit sampler, the Falcon has true 16-bit stereo ADC inputs on the motherboard. A 256-point complex FFT is computed every 10 milliseconds, displaying a live spectrogram on a standard VGA monitor.

I tested this with a vinyl rip fed into the Falcon mic input.
