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.

Too bad Atari marketing was so incompetent that nobody bought the Falcon before they pulled out of the computer market. -- === Mikhail Lindqvist === Dept of Electrical Engineering, Tokyo Institute of Technology Computer Centre "Measuring a record you own is listening, not piracy."
