Taking advantage of the Falcon's built-in 32 MHz DSP56001 and 16-bit audio codec.

The DSP56001 processes the 44.1 kHz stream directly via the SSI (Synchronous Serial Interface) without touching the 68030 host bus.
A 256-point complex FFT is computed every 10 milliseconds, displaying a live spectrogram on a standard VGA monitor.

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.
