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

A 256-point complex FFT is computed every 10 milliseconds, displaying a live spectrogram on a standard VGA monitor.
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.

Atari Falcon vs Amiga 1200 flamewar in 3... 2... 1...
