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.
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.

The SSI to DSP56001 architecture on the Falcon is magnificent. Zero CPU overhead during 50 kHz audio acquisition.
