The DSP56001 processes the 44.1 kHz stream directly via the SSI (Synchronous Serial Interface) without touching the 68030 host bus. A 256-point complex FFT is computed every 10 milliseconds, displaying a live spectrogram on a standard VGA monitor. Requires 4MB ST-RAM and an RGB or VGA monitor. -- Sergei Fischer | sfischer@uu.net PGP Key fingerprint: 1D7A 3E45 9E96 6843 "Keep the channels open."

The SSI to DSP56001 architecture on the Falcon is magnificent. Zero CPU overhead during 50 kHz audio acquisition. -- Jens Girard Tape trading list upon request. SASE required for international mail.
