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. -- Karen Weber "A soul is not exclusive to biology."
