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.

I tested this with a vinyl rip fed into the Falcon mic input.

Too bad Atari marketing was so incompetent that nobody bought the Falcon before they pulled out of the computer market. -- Mathieu Ivanov -- Oxford University Computing Laboratory "We don't sign stars.
