Hi all, well I'm a fan but a weak helper-outer it turns out, between work and school I'm useless here. But here's a few small items.
0) All my interface crashing woes ended with patches dating back a few months now. Late news, but I fogured I'd say thanks for the work. 1) Was unable to compile a recent version on ubuntu 8.04. To make a long story short --silence-errors in pkg-config QtOpenGl invokation hid the error; manually invoked w/o --silence-errors revealed that it could not find libqt4-opengl-dev. apt-get install that, scons compiled fine, and versions since. I had been compiling just fine before that. Sorry, no rev number(s) to report. 2) I've been unable for some time to reduce latency to anything really useful; the best I could achieve was 49mS (!); less than that got the usual pops and gapping. Turning waveform to simple helped somewhat. This, on a machine designed for low-latency music (dual core 2.4GHz, 4GB of very fast RAM, etc). Poking around on a related problem found a thread involving RT latency and cpufreqd. So at a mere whim I apt-get purge'd it, and install cpudyn instead. Voila! I could run latency down to 2 (two!) mS with occasional pops; 4mS no pops (but read on). With waveform on, two tracks mixing centered fader, etc. Before I posted I figured I'd do some regression, so I purge'd cpudyn, reinstalled cpufreqd, expecting... still works at 4mS. So much for that theory. I assume that soemthing like a bad install/upgrade/etc crossed up the daemon, and now I'll never know. --> If you can't drop latency on a fast machine, try purging/reinstalling cpufreqd and/or cpudyn. There does seem to be some issue with frequency scaling in Hardy. 3) "Latency leak" -- confounded w/previous results, I thought I'd set latency to 4mS, put two tracks on, and leave it running. After a day or two -- mild pops. Then adjusted latency to 6mS, problem went away, and after another 24 hours of continuous play, did not pop. I repeated this twice (took a week, that's how busy I've been :-). So 6mS is more than acceptable, but there is something funny in there. No complaints here, it's working just great. ------------------------------------------------------------------------- Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!
