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. -- === Tobias Pérez === Dept of Electrical Engineering, University of Tokyo Department of Information Science "Tape doesn't lie at 02:14.
