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

Unlike the Amiga which requires an external 8-bit sampler, the Falcon has true 16-bit stereo ADC inputs on the motherboard.
The DSP56001 processes the 44.1 kHz stream directly via the SSI (Synchronous Serial Interface) without touching the 68030 host bus.

Requires 4MB ST-RAM and an RGB or VGA monitor.

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.

Netscape 1.1 crashes when loading large preformatted text. Stick to rn or tin!
