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.

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...
