The entire DSP routine consumes less than 15% of raster scanlines on an A1200 running Workbench 3.1. I wrote a 64-tap FIR filter in pure 68k assembly using movem.l and dbra loop unrolling to downsample to 64 Hz. Source code and executable will be released on Aminet under mus/misc/stardust_amiga.lha next week. -- Matthias González | mgonzalez@netcom.com PGP Key fingerprint: 7BDB E953 4FB5 9F45 "Keep the channels open."
