Hello, all, I tried to replace my audio stack on my everyday, all-purpose Linux Ubuntu 18.04 desktop with PipeWire. Overall, it went smoothly, with one exception. So far, I've mainly used it to listen to audio from Firefox, from YouTube videos, etc. Every time I perform an action on the YouTube video (start or stop the video, move the timeline back and forth, change the playback speed, etc.), the Sound control panel either shows a new Firefox source, under the Applications tab, with the volume set to zero, or the existing Firefox source is slid to zero. Before I can hear anything, I have to bring up the Sound control panel and slide the control up. I know this isn't a PipeWire support forum, but I haven't been able to find one for PipeWire under Linux or Ubuntu. Does anyone know of a support or user's forum where I could ask this question? Where would you go to ask this question? Thanks for your help and advice. -Kevin

Sonoj Convention 2022 - October 8th and 9th (?)

by Sonoj Convention

Dear past and future visitors of the Sonoj Convention, the following message is made under the assumption that the world will return to a more healthy and peaceful state until October 2022. At this point in time, I am unable to make any guarantees. Sorry. However, the date is fixed. The convention will either be on this weekend (see below) or it will not happen at all. The fourth annual Sonoj Convention ( https://www.sonoj.org ) will maybe(!) taking place this upcoming October 8th-9th 2022 in Cologne, Germany. The convention is focusing on the combination of music production and free / open source software, with a priority on practical music production. We want to welcome everyone, regardless of your musical or technical background. As it was the last times, admission to the convention is free. While the website https://sonoj.org/ is still in it's "in-between" mode it will soon be replaced by the real site again, with more information. To get a better idea of what to expect out of Sonoj, you can find information and recordings from last year's conventions in our archives: ( https://sonoj.org/archive ) If you want to contribute with a demonstration or talk, please contact me ( info(a)sonoj.org ). A short, informal expression of intent will be enough for now. Yours, Nils Hilbricht Cologne, Germany https://www.sonoj.org

[music] Fire Wheels (Slaphouse)

by Jeanette C.

Hey hey, yes, my attempt at slaphouse: https://youtu.be/qxwqgEK1dvc OGG version: https://www.dropbox.com/s/6skfzbjk35l3x2h/fire_wheels.ogg The difficulties, from my point of view and environment, were: getting the sidechain compressor going and putting in the high- and lowpass filter automation on the mix. Slaphouse is a house subgenre of a year or three ago in Brazil, AFAIK. I stumbled across it, thought it was easy enough, but technically challenging enough, to give it a go and prove that I could do it. Very special mention goes to: Yoshimi for a bass that slaps and is so wide it hits you round both ears at the same time. :) Best wishes, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c Our imagination Taking us to places We have never been before... <3 (Britney Spears)

Csound question

by Fons Adriaensen

Hello all, See below... What I want to achieve is to take some action when instr 85 ends. I naively tried using 'gidur' as p3 for instr 85 in the score, but that doesn't work. So how do I trigger instr 86 at the right time ? <CsInstruments> instr 84 gidur filelen $INPFILE print gidur endin instr 85 ; set its duration from the value found in instrument 84 p3 = gidur ; process input from $INPFILE endin instr 86 ; Should do something when instr 85 ends. endin </CsInstruments> <CsScore> i84 0 0.1 i85 + 1 ; p3 is just a dummy </CsScore> TIA, -- FA

Analysis of monophonic audio signals on the commandline

by Jeanette C.

Hey hey, I am looking for tools to analyse bird song. I have many recordings, which can probably be cleaned up enough to have single calls as good as isolated. On the other hand there are quite a few sonograms of bird calls, used to identify species. What I am looking for is a kind of mathematical analysis tool to get an idea of frequency and volume, perhaps with an estimate of curves. I suppose that requires statistical analysis. This is far from my forte, so I wouldn't know which keywords for the relevant math to enter and in which tool to look. Are there audio specific programs? Or is a math package like R, octave or maxima able to handle such data input and the task? If you are not immediately aware of a relevant tool, but could supply me with a few keywords and considerations, that would already be quite helpful.

Re: [LAU] Analysis of monophonic audio signals on the commandline

by bil＠ccrma.Stanford.EDU

I think what Fons says is correct. You can get close using just a sine wave and two complicated envelopes for amplitude and frequency. I did a bunch of bird songs this way back around 1980 -- see bird.scm in the Snd package. These are in Scheme using CLM, but it should be easy to grab the envelopes and use them elsewhere. The Snd package also has animals.scm: much more sophisticated attempts to synthesize birds, frogs, insects, etc. There's a brief discussion of that file in sndscm.html#animalsdoc also in the Snd package. But in any case, listen to say a hermit thrush or a red-winged blackbird slowed down and transposed down -- unbelievably beautiful! I really had a blast trying to synthesize these songs.

kernel 5.15 irqs

by Len Ovens

In older kernels running: pa ax |grep irq will show a process for each irq in the form: 548 ? S 0:00 [irq/16-snd_ens1] however, with kernel 5.15 most of these are gone except the one for mei_me. This means that rtirq doesn't work and my device suffers from more xruns than normal. Has anyone else experienced this? -- Len Ovens www.ovenwerks.net
