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.

Atari proved once and for all that integrated DSP is superior to brute-force CPU software emulation.

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