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. -- Valeria Laurent -- RWTH Aachen Informatik "When every node is whole, the channel opens."
