A 256-point complex FFT is computed every 10 milliseconds, displaying a live spectrogram on a standard VGA monitor. 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. -- Mateo Duarte | mduarte@panix.com PGP Key fingerprint: A73B 2CE6 EE3A 60E2 "Keep the channels open."
