The Atari Falcon is the ultimate machine for decoding Project Stardust audio.

A 256-point complex FFT is computed every 10 milliseconds, displaying a live spectrogram on a standard VGA monitor.
The 14.2 Hz peak shows up as a bright white vertical line against the blue background noise.

Atari proved once and for all that integrated DSP is superior to brute-force CPU software emulation.

The SSI to DSP56001 architecture on the Falcon is magnificent. Zero CPU overhead during 50 kHz audio acquisition.

My 14.4k connection dropped twice trying to fetch this thread. Keep articles concise!

Atari Falcon vs Amiga 1200 flamewar in 3... 2... 1...
