Actually, my reasons may sound a little strange, but basically I'd be fine with HZ=1000 if it wasn't for that annoying ~1 kHz sound when the CPU is idle (probably bad capacitors). By increasing HZ to 10 kHz, the sound is at a frequency where the ear is much less sensitive. Anyway, I thought some people might be interested in high HZ for other (more fundamental) reasons, so I posted the patch. Jean-Marc -- Jean-Marc Valin, M.Sc.A., ing. jr.
