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.

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.
