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

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.

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