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

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

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