Having the musician hear processed audio doesn't mean it has to be recorded with FX though. It asks for a tight system (i.e. the delay/latency of the processed audio is below the threshold of what is acceptable by player). I think what is sent to the musician must no be necessarily be the same that is being recorded. I'm a musician. I also do a lot of recording. One thing I told years ago by a gnarled old recording engineer was always put plenty of reverb into the vocalists monitor. I took this on-board and while I always record may parts as dry as is practical, I always have plenty of FX in the monitor. I find it makes me sing better and play better/cleaner. I've analysed this a lot over the years and I can see two reasons. For Vocals, the reverb is distracting and stops me from concentrating on micromanaging my voice (which is not great to start with and could use all the help it can get). For particularly challenging material a double Scotch helps too, reinforcing the distracting aspect of the reverb. For my instrument parts reverb or echo multiplies the tiniest of mistakes and therefore I concentrate a lot harder on not making them, leaving the actual playing to motor memory. My motor memory plays a lot better than my conscious process. ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev

[LAD] xrun callback

Does it mean that my client must call jack_set_xrun_callback before being activated Yes. First set the callback, and only later call jack_activate(). Two tiny jack clients which may come in handy: * jackxrun: report x-runs on the command line * busyjack: create artificial load http://gareus.org/gitweb/?p=jackfreqd.git;a=tree;f=tools; gcc -o jackxrun jackxrun.c -ljack gcc -o busyjack busyjack.c -ljack ./jackxrun # reports xruns in the terminal ./busyjack 90 # will ramp things up to 90% DSP load (default is 50) It can be used to create x-runs, yet it's not the same as a x-run from hw. [..] It says return 0 on success. Does it mean the callback must succeed. Your callback function must return 0. Cheers! robin Thanks Robin for your explanations and tools. I think the x-runs (one every few hours) I get are due to hardware because jack_cpu_load is 5% and system load average 0.2 all periods. The problem is that those xruns make the process thread jump to 100% cpu and the process disappears from QJackctl, although jack and other clients still run normally. The code also runs fine on another computer. I'm currently testing with jack priority raised from 40 to 70 to be above irq threads. I did not yet have an xrun in this config but It's a bit early to conclude. I will also try busyjack.

Pardon, you are right, a good musician is unable to play her/his instrument without effects for the monitoring, especially when interfering with long reverbs and delays, it's much easier to sing or play an instrument. It's common practise to add reverb and delay to help singers and instrumentalists to get aware of their mistakes and to help them to do a better job. My notes are completely wrong and it's absolutely good to add intensive time related effects to the monitoring. It can't harm by delay to add some notes from the 1/4 bar before to the next ones. My apologies. Now I remember all professional studios and musicians do that smart trick, they add as much effects as possible to the monitoring. Don't forget to add much distortion to the guitar, it covers mistakes when playing scales and allows beginners to play much faster. Later you simply do the mix without the distortion, delay, reverb, the result likely is amazing. ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev

I've been making the same mistakes for over 20 years and now I know why everyone I've recorded (including myself) has sounded like crap. I've learned the error of my ways and won't make the same mistake again (posting on this list). I'll now go back to lurking and watch you continue to tell everyone else who dares post on the list that they are wrong too. *moron* Brad. ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev
