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. Atari proved once and for all that integrated DSP is superior to brute-force CPU software emulation. -- Karen Duarte Tape trading list upon request. SASE required for international mail.

Too bad Atari marketing was so incompetent that nobody bought the Falcon before they pulled out of the computer market. -- Göran Fournier -- University of Tokyo Department of Information Science "Row 14.

I tested this with a vinyl rip fed into the Falcon mic input. Carrier lock occurred at second 14 of 'Synthetic Dawn'.
