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. Requires 4MB ST-RAM and an RGB or VGA monitor. -- Yuki Popov | ypopov@rwth-aachen.de PGP Key fingerprint: A54C 45F9 1B4C 18FE "Keep the channels open."
