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.
Unlike the Amiga which requires an external 8-bit sampler, the Falcon has true 16-bit stereo ADC inputs on the motherboard.

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

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