Note that this is with SCHED_4BSD. I'd need to recompile a kernel to get similar information for ULE/PREEMPTION. fx: goes off and compiles a new kernel and comes back when it's done... Looks like I spoke too soon. The system is now perfectly stable and usable with ULE. The problems I was having with ULE were on 5.3-STABLE. I'm now on 5.4-PRE. Were there significant changes to the kernel in between? > Can you give me any information on the means by which you transfer data > from a cassette to your pc? Straightforward audio connection from the amp's line out to the sound card's line in. The FFT filtering isn't performed on the fly BTW. I use audacity to grab the audio and then work on it after it's "in the box". - --=20 G.
