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.

Too bad Atari marketing was so incompetent that nobody bought the Falcon before they pulled out of the computer market. Netscape 1.1 crashes when loading large preformatted text.
