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

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

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