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.

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

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

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

Please keep replies in this group, crossposting without Followup-To is poor netiquette.
