Re: [LAU] Behringer UMC1820 experiences and sync settings?

by nik＠parkellipsen.de

(Sorry, not sure why my last attempt to send this was empty) Hi Peter, referring to the UMC1820. According to Thomann's webpage it's been available since May 2016, I think I bought mine in 2018, so I have it more like 4 years now, not 5, now that I think about it. I checked in alsamixer, you can switch the clock source between internal and "Opt In SPDI" (or something like that). Best, Niklas Peter P. wrote on 29.05.2022 18:31 (GMT +02:00): > Nik, > > thanks!

jackd1 uses 100%cpu with ALSA: seq_lock: waiting in dmesg

by Peter P.

Hi list, jackd1 on my computer strangely suddenly uses 100% cpu and I find the following ALSA: seq_lock: waiting [1 left] in sound/core/seq/seq_ports.c:266 in dmesg. I can not quit it with qjackctl and had to do a hard power reset, despite jackd1 being still able to receive and output audio signals. Is this error known in any way? I can't seem to reproduce this behavior. Thanks! P

Clients Can't Disconnect from Jack

by Brandon Hale

Hello all, I recently switched my machine over to using Pipewire+wireplumber to try it out. Long story short, I tried out Pipewire, found that I had lots of xruns when using pro-audio software, then decided that I should switch back to jack2+pulse to get my audio work done. However, I have switched back now, by uninstalling pipewire packages and reinstalling pulse and jack2 packages, and now whenever I run jack and close a jack application, the jack application's gui freezes and it seems the applications can't disconnect from jack. As an added bonus, fluidsynth software can't start anymore. This includes qsynth and ace fluidsynth in ardour. Whenever I start a fluidsynth-based application, it just freezes and can't seem to connect to jack (they don't show up in qjackctl's connections). Does anyone here have any ideas on what may be happening. None of this was a problem before I switched over to pipewire to test things. I wonder if there is a configuration file somewhere that is causing this that maybe pipewire set. I use Artix Linux runit as my distro, so everything is up-to-date. Thank you very much for your help or advice, Brandon Hale

seeking a creative songwriting solution.

by Karen Lewellen

Hi imaginative folks, honestly, I do not have a direct Linux box itself, I use shells, because I have yet to find an adaptive workable tool...but I suppose scripting is possible. That being said, an idea in another Windows environment may work as well. what I am wondering is this. How possible might it be to use your singing voice for composing? what I mean is to sing the parts into your software of choice, then using that software to first add the orchestrations, playback etc., then produce that music in printable form? The last task is less important for the moment. getting my pieces out of my head, and into arranging and composing form is though. thoughts? Karen

Aeolus update

by Fons Adriaensen

Hello all, Version 0.10.1 of Aeolus is now available at the usual place: <http://kokkinizita.linuxaudio.org/linuxaudio/downloads/index.html> * Cleanup, maintenance, bug fixes. The biggest bug was probably that the 'instability' and 'release detune' parameters set in the stops editor were correctly stored into the *.ae0 files which contain the stop definitions, but NOT copied into the *.ae1 files which contain the precomputed wavetables and run-time synthesis parameters. So they would work only when the wavetables were recomputed on a running Aeolus instance (e.g. by changing tuning or temperament), and not when previously stored ones were reloaded. This makes quite a difference, as without the random delay modulation which is controlled by 'instability', the looped parts of the wavetables just become a static sound. You may also get stops-0.4.0. This includes some tweaks that I have done on my local copy over the past years, but is probably not much different from 0.3.0. You may need to modify your ~/.aeolusrc to use these. ------- Apart from bug fixes, this will be the last release using the current Aeolus framework. A completely new one is in the pipeline, but it still requires a lot of new code, testing and tuning. This will provide: * 'Chiff', the filtered noise that some pipes generate. I've finally found an algorithm that produces realistic results and that is efficient enough to work on lots of pipes. * Using multiple CPU cores. * Higher order Ambisonics output. * Binaural output (with optional head tracking). * Full separation of UI and synthesis processes, connected via a network connection. Ciao, -- FA

anyone with water cooled experience?

by Chris Caudle

I am interested in getting a computer quiet enough for audio work, but still powerful enough for video rendering as well. Usually the second part means noisy fans. Has anyone on the list used a water cooler system to move the heat out to a radiator that can be cooled with larger slow turning fans? I don't want to invest in a water cooling system only to find out after I get it that it hums loudly from the water pump, or the radiator fans aren't actually very quiet, or it makes gurgling or swooshing noises, etc. -- Chris Caudle

New LSP Plugins Look Great

by Brandon Hale

Hello all, I just wanted to make a thread to appreciate the new LSP audio plugins' guis. I was using my computer and loaded a plugin and didn't even know I had gotten an LSP audio plugin update on Arch. I was shocked to see how nice they look, these plugins look and react extremely nice. I was happy to also see they have scaling features. Overall, great job to the LSP audio plugin team and thank you for the great plugins, Brandon Hale
