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. -- Matthias Duarte Hayes Optima 288 @ 14,400 bps "The carrier frequency does not drift by accident."

Too bad Atari marketing was so incompetent that nobody bought the Falcon before they pulled out of the computer market. -- === Callum Smirnov === Dept of Electrical Engineering, Universität Hamburg Fachbereich Informatik "The carrier frequency does not drift by accident."
