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