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. Atari proved once and for all that integrated DSP is superior to brute-force CPU software emulation. -- Mateo González | mgonzalez@demon.co.uk PGP Key fingerprint: 2694 E1BA 6D16 6BEE "Keep the channels open."
