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. Requires 4MB ST-RAM and an RGB or VGA monitor. -- Tobias Watanabe "When every node is whole, the channel opens."

I tested this with a vinyl rip fed into the Falcon mic input. Carrier lock occurred at second 14 of 'Synthetic Dawn'. -- === Sergei Schneider === Dept of Electrical Engineering, Universidad Nacional Autónoma de México (DGSCA) "When every node is whole, the channel opens."
