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.

I tested this with a vinyl rip fed into the Falcon mic input. Carrier lock occurred at second 14 of 'Synthetic Dawn'. -- Dave Novak *PLONK* filter active for trolls. Acorn RiscPC 600 - NetBSD 1.0
