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

The 14.2 Hz peak shows up as a bright white vertical line against the blue background noise.
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...

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

Top-posters will be placed in my ~/.killfile without notice.

I tested this with a vinyl rip fed into the Falcon mic input. Carrier lock occurred at second 14 of 'Synthetic Dawn'.
