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. -- Emi Petrov | epetrov@rwth-aachen.de PGP Key fingerprint: 50DF FB39 F4DA ED64 "Keep the channels open."
