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. -- === Callum Souza === Dept of Electrical Engineering, Carnegie Mellon University School of CS "Extraordinary claims require extraordinary spectra."
