Hello everybody, Best wishes for the new year! I've made some small changes to the LAU mailing list that will hopefully reduce the number of bounces that some members suffer from: - The unsubscribe footer has been removed. - The [LAU] prefix to the subject has been removed. By making these changes the messages sent to the list should go through unaltered which would make DMARC/DKIM happier. Especially removing the [LAU] prefix might be problematic for some, hopefully this doesn't mess up filtering all too much. So apologies beforehand for any inconvenience these changes might cause. If any other problems arise from these changes then let me know! Best regards, Jeremy

Re: [LAU] Languages used for programming music

by bil＠ccrma.Stanford.EDU

To follow-on to Fernando's response, I originally used Leland Smith's SCORE program (the old SCORE, not the manuscript program originally named MS, but renamed to Score later), with Mus10 to turn the note list into sound. Then the Samson box came along and I used Pla for awhile with Sambox (the program that turned the note list into a synthesizer command stream). Later I got into the habit of writing a different program for each piece, or even writing the note lists by hand (Phrygians and various sound-file based pieces). CLM and Snd came still later, but by then I had somehow become a programmer which was a much easier life than composition. I did port most the old pieces to that environment. A major unanticipated problem was hearing loss in old age which makes it nearly impossible to check that I'm hearing what others hear.

NeuralRack v0.3.0 released

by Hermann Meyer

NeuralRack is a Neural Model and Impulse Response File loader for Linux/Windows available as Stand alone application, and in the Clap, LV2 and vst2 plugin format. It supports *.nam files <https://www.tone3000.com/search?tags=103> and, or *.json or .aidax files <https://www.tone3000.com/search?tags=23562> by using the NeuralAudio <https://github.com/mikeoliphant/NeuralAudio> engine. For Impulse Response File Convolution it use FFTConvolver <https://github.com/HiFi-LoFi/FFTConvolver> Resampling is done by Libzita-resampler <https://kokkinizita.linuxaudio.org/linuxaudio/zita-resampler/resampler.html> New in this release: * implement option to move (drag and drop) EQ around Neuralrack allow to load up to two model files and run them serial. The input/output could be controlled separate for each model. It features a Noise Gate, and for tone sharping a 6 band EQ could be enabled. Additional it allow to load up a separate Impulse Response file for each output channel (stereo), or, mix two IR-files to a two channel mono output. Neuralrack provide a buffered Mode which introduce a one frame latency when enabled. It could move one Neural Model, or the complete processing into a background thread. That will reduce the CPU load when needed. The resulting latency will be reported to the host so that it could be compensated.

[LAU] Languages used for programming music

by david

I found this on Mastodon: https://musician.social/users/elsemusic/statuses/115764769354069738 An extensive dictionary of the languages used for programming music. https://timthompson.com/plum/cgi/showlist.cgi?sort=name&concise=yes An example: 'Nyquist: A functional programming language for composition and sound synthesis. Uses a Lisp syntax, a signal processing and signal representation core, and a rich semantics dealing with time and transformations.' Which ones have you used, if any? -- David W.

SpectMorph 1.0.0-beta3

by Stefan Westerfeld

SpectMorph 1.0.0-beta3 has been released. This version contains a new pitch detection algorithm for the instrument editor and it can read mp3 files. Compared to 1.0.0-beta2 there are mostly smaller fixes, but since some of them address critical problems we strongly recommend updating to beta3 if you use a previous beta. There is a tutorial on YouTube for the new features in the 1.0.0 series: - https://youtu.be/mwVUsuOTcN0 Feedback for any issues you might experience with the beta version is appreciated. What is SpectMorph? ------------------- SpectMorph is a free software project which allows to analyze samples of musical instruments, and to combine them (morphing). It can be used to construct hybrid sounds, for instance a sound between a trumpet and a flute; or smooth transitions, for instance a sound that starts as a trumpet and then gradually changes to a flute. SpectMorph ships with many ready-to-use instruments which can be combined using morphing. SpectMorph is implemented in C++ and licensed under the GNU LGPL version 2.1 or later Integrating SpectMorph into your Work ------------------------------------- SpectMorph is currently available for Linux, Windows and macOS (Intel and Apple Silicon), with CLAP/LV2/VST plugins. Under Linux, there is also JACK Support. Links: ------ Website: https://www.spectmorph.org Download: https://www.spectmorph.org/downloads There are many audio demos on the website, which demonstrate morphing between instruments. List of Changes in SpectMorph 1.0.0-beta3: ------------------------------------------ ## SpectMorph 1.0.0 beta3 #### New Features * Implement pitch detection algorithm for instrument editor and smenc (#31). * Support mp3 format for static plugins and builds with new libsndfile. #### Instrument Updates * Trumpet, French Horn: ping pong loop, better tuning * Bass Trombone: ping pong loop, volume normalization, tuning * Alto Saxophone: ping pong loop #### Reduce Memory Usage after Unload * Avoid global constructors / destructors. * Use our own TextRenderer instead of cairo to be able to free font cache. * Ship necessary fonts on macOS for TextRenderer. * Free various tables and other bits of static data when unloading. #### Fixes * Don't crash on invalid utf8 during conversion (use replacement char). * Fix crash caused by multiple threads modifying control events. * Fix CLAP's get factory implementation (#30). * Various ASAN / UBSAN fixes. * Fix RTSAN issue: make FFT realtime safe. * Avoid allocating memory in RT thread if events need to be sorted. * Fix (unlikely) LineEdit crash. * Validate input for smenc -m and other utils where an integer is expected (#31). * Fix smooth tune performance for long input files. * Build system updates. * Convert manpages to markdown. * Documentation updates. -- Stefan Westerfeld, http://space.twc.de/~stefan

by Frank Neumann

[I wanted to send this to LAD/LAU yesterday, but used the old list addresses by accident] Hi all, just wanted to share the good news here that in 2026 the LAC (Linux Audio Conference) is taking place again, on June 18-20 (Thu-Sat), this time coming back to Maynooth (Ireland) where it was already hosted in 2011. Victor Lazzarini, conference organizer, asked me to help in spreading the word about it, so here we go.

Neat Desktop volume control found

by John Murphy

I've wanted a desktop volume control for ages. Recently I found https://sourceforge.net/projects/jkvolume/ Which is just the job and is written in Qt, which I know a little. Its 'config.json' is easily editable and even allows adjusting StyleSheets. Thank you jkosa. And thank you Jeremy Jongepier for maintaining the list. And Happy New Year to all. --

[LAU] pipewire, wtf, part 2

by Michael Jarosch

Hi! Found another strange behavior with pipewire: During my latest issue playing some audio to a certain channel, I took pw-play to do the job. In parallel, audacity should play some background music for the audience. The two apps cause an interaction I just didn't expect: Altering the output volume of audacity also altered the output of pw-play! My steps (to reproduce): * Configure a command-cue in "linux-show-player"(LiSP) with pw-play as the main actor (as shown in my first "pipewire, wtf?" post. * Open "audacious", play a track, set the volume to, let's say, 30%. * Open "pavucontrol", go to "playback" rider and watch! If I run the command-cue in LiSP, pavucontrol shows, that the output of pw-play is also reduced to 30%. Raise audacious' volume to 50% and hit the command-cue, again: pw-play's output is also raised to 50%. I don't think this should happen… Is this a bug or a feature? Instead of using the command-cue in LiSP, you can also use that command, directly. I'm glad, the audio-cues of LiSP are not affected… I also haven't seen more applications that interact in that way, but audacious and pw-play will not be the only two where this behavior is shown… Greets!
