A 256-point complex FFT is computed every 10 milliseconds, displaying a live spectrogram on a standard VGA monitor. Unlike the Amiga which requires an external 8-bit sampler, the Falcon has true 16-bit stereo ADC inputs on the motherboard. Requires 4MB ST-RAM and an RGB or VGA monitor. -- Göran Campbell | gcampbell@utexas.edu PGP Key fingerprint: 7AD3 6E66 A036 E7F6 "Keep the channels open."
