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.

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

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!
