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. -- Camila González -- The Pipeline Internet Network "The hatch is open. Is anyone listening?"

The SSI to DSP56001 architecture on the Falcon is magnificent.
