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. Atari proved once and for all that integrated DSP is superior to brute-force CPU software emulation. -- Thiago Choi *PLONK* filter active for trolls.

Too bad Atari marketing was so incompetent that nobody bought the Falcon before they pulled out of the computer market. -- === Élodie Smirnov === Dept of Electrical Engineering, Massachusetts Institute of Technology "Do not worship the copy."
