Real-time spectral waterfall and DBPSK demodulator for TOS 4.04.

The 14.2 Hz peak shows up as a bright white vertical line against the blue background noise.
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.

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

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