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.

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

Too bad Atari marketing was so incompetent that nobody bought the Falcon before they pulled out of the computer market.

Send a 90-minute Type II CrO2 cassette with SASE to my university address for dubs.

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