[LAU] Looking for a cLI recordiing solution / ideas, brainstorming

by Jeanette C.

Hey hey, I just heard that Ecasound, as robsut as its code is, is slowly moving out, requiring more and more patches. So I should really look for a new solution. Why CLI? I had a GUI running on my system, with JACK, and found that Orca was very sluggish, not condusive to fast efficient work. Besides, there are quite a few LV2 plugins which are built on JUCE and JUCE Uis are not accessible on Linux. Last thing I heard, they added accessibility but only to mac and windows. So back to the commandline. LV2 plugins can be controlled there, mod-host a case in point. Though, admittedly, I found quite a few plugins with quite meaningless parameter ranges. Still, they can be used. Does anyone have any ideas? Perhaps something that is in its early stages or a UI that was created for testing or automation and might offer more beyond that purpose? -- Any suggestions or hints are welcome. For the time being, Ecasound will run, but its life-cycle looks definitely finite in the foreseeable future.

[LAU] NeuralRack v0.2.0 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-resam… New in this release: - implement Mix mode for IR convolver. - implement support for ASIO control panel (Windows) ![NeuralRack](https://github.com/brummer10/NeuralRack/raw/main/NeuralRack.png?raw=true) Neuralrack allow to load up to two model files and run them serial. The input/output could be controlled separate for each model. 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). 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] [Music] Friends

by Jeanette C.

Hey hey, here's a new song called Friends: https://youtu.be/kO-fozsPB_A It moves between progressive rock and power ballad, I suppose. Thematically, it's perhaps even closer to my heart, lovely modulations aside. :) And no, I never had a friend called Matilda or someone like her. I'm very glad about that. You'll find the lyrics at the end. First, here are the instruments I used: a lot of Yoshimi for the bell-like sound, the pad, the choir and the soft chord instrument heard in the beginning. LinuxSampler for the Rhodes, acoustic piano, strings and acoustic guitar, as little as there is of it, and of course the Carillon. Drumgizmo for the drums. Fluidsynth for the bass and Csound for the electric guitar. The lead sounds are analogue hardware, the Behringer Neutron and Arturia Minibrute 2S respectively. It was again recorded with Midish and Nama. Processing courtesy of - in no particular order - Caps, Invada, zita-reverb, Calf, SWH, CMT, g2verb, TAP plugins and 4-band parametric EQ. Ah, and I shouldn't forget AutoTalent. What can I say? I'm very glad it exists and with even more tweaking it would have been less obvious. And here are the lyrics, hope you enjoy it: Today, I met Matilda again. She stated: you're no more a friend of mine. When I asked the reason why, She mutely turned her back. Today, I lost my oldest friend And I don't even understand. So mad, so sad I can't believe it. Bereft, I stare into space, while I'm grievin'. As I seek the reason why, I'm swallowed by the void. Today, I lost my oldest friend And I can't understand. Today, per chance, I got the story. Her political creed made it mandatory To look askance at my way of life. Why is it us or it's them? Either for or against? Do you know? Today, we lost a thousand friends, Does any one know where it eends? Matilda, it's time that we come to our senses. We have done it before, let's be mending fences. We never were in full accord, There is no need to be... Let's break the circle of defiance and fear! This farce, it ends right here. Today, I met Matilda again. We argued and laughed all through the night. We din't part till the morning light, Two sides of a coin in accord. Today, we stood as closest friends. 'Cause now, we understand.

[LAU] [ANN] Dynamic Range Destroyer LV2 plugin (DRD.lv2)

by David Flater

(Revised and resent because the original message to LAU was rejected.) Dynamic Range Destroyer (DRD.lv2 or simply DRD) is an audio compressor plugin that aims to remove changes in volume from an audio stream. This effect is also called auto volume levelling, volume normalization, or "stable volume." It supports mono, stereo, 6-channel, and 8-channel streams, and it preserves the balance among channels. DRD is not a peak limiter, and it does not drop the volume to avoid or prevent clipping. Its behavior is intentionally similar to that of the compand filter of FFmpeg. https://github.com/DaveFlater/DRD To install as a global system audio filter for Linux with PipeWire, see https://flaterco.com/kb/audio/pipewire/volume.html

[LAU] [ANN] Qtractor 1.5.7 - A Summer'25 Release

by Rui Nuno Capela

Hi all, Qtractor 1.5.7 (summer'25) is out! Change-log: - Give some slack time to stabilize, when updating or changing audio bus channel counts, mitigating the probability to fault when unregistering old and registering new PipeWire/JACK ports in immediate succession. - Transport/Loop Set behavior slightly changed, now toggling the loop range if the edit-head/tail match current loop-start/end. - Introducing Aux-Send audio bus I/O matrix functionality. - Corrected greater-than-2-channel audio clip waveform drawing, while on certain zoom levels, an old bug lurking there since dawn, quite an example to the evil of too-early optimization ;) - Draw all audio clip peaks+rms waveforms slightly compressed, so that low-level signals have improved visibility. - Warn when saving any type of session into an extracted archive directory. Description: Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

[LAU] KVR Music Cafe Contest

by Will Godfrey

This month's theme is "angry music" and the time limit is 4 minutes. My entry is a cover... of Ride Of The Valkyries (and you don't get much angrier than those!) I started with a couple of free on-line MIDI files, but wasn't happy with either of them, so took the best one, then modified it with bits of the other one, along with comparative listening to actual recordings (no two of these were even mostly similar), finally getting creative with my own ideas. It's all Yoshimi... instrument patches in no particular order: Synth Strings * 2 Full Strings Wet Brass Wet Brass2 Prophesy Post Horn Clarinet Yet Another Flute {percussion} Crash Full 2 Hugh's Kit Slow Cymbal (created just for this) Ride Crash Soft Kick You can find it here (it won't stay there much after this month) http://www.musically.me.uk/Misc/2507_folderol_Ride_Of_The_Valkyries.mp3 -- Will J Godfrey {apparently now an 'elderly'} https://willgodfrey.bandcamp.com/ http://yoshimi.github.io Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

[LAU] FLOSS Audio editors on Linux: are they all dead(-ish)?

by Lorenzo Sutton

Hi LAU and LAD, It seems that (FLOSS) audio editors (not DAWs) are all either dead/obsolate (mhwaveditor, rezound), in strange development states (Audacity, Tenacity). Tenacity, the most promising (albeit with its audacity-inherited idiosyncrasies) has a really annoying bug [1] which makes it take ages to load [1] - IMHO a no go for an audio editor IMHO (plus its multi-track-ness like Audacity makes it overload for a few use cases). The only more-or-less usable one at the moment is ocenaudio which is not free software (and also has some UI quirks, but that's maybe personal). I've been a fan of mhWaveEdit for its mix of simplicity and configurability, but as an abandoned GTK2 application it shows its problems. Is this kind of software not interesting any more? Are people using DAWs for everything? Are people even using, or interested / committed in using Linux Audio any more? As LAC approaches (unfortunately I won't be able to attend, even though it's in Europe), why not try to spark some debate :-P Lorenzo [1] https://codeberg.org/tenacityteam/tenacity/issues/549

[LAU] [ANN] JACK Rack 1.5.0 released

by Adam Sampson

JACK Rack 1.5.0 is out! Downloads: https://sourceforge.net/projects/jack-rack/files/jack-rack/ Git repo: https://sourceforge.net/p/jack-rack/git/ci/master/tree/ Home page: https://jack-rack.sourceforge.net/ It's been 18 years since the last release, but for those of you who still have a use for a lightweight LADSPA plugin host, here's a version that'll build with modern compilers (although it still needs GTK+ 2) and includes several other improvements contributed by users over the last couple of decades. If you're maintaining a package of this, note that the dependencies have changed and the tarball is signed by my newer GPG key. Changes in this release: * Update the code so that it can be built with any language standard from ANSI C to C23. (The previous release doesn't build with GCC 15, which defaults to C23.) * Fix memory leaks and other minor problems reported by GCC and Clang's analysis tools. * Update the build system to support current autotools. * Don't try to link against the GNOME 2 libraries, and make the About window available without them (patch from James Morris). * Replace a call to a LASH internal function with a glib equivalent. * Rework the rack saving/loading code to be more robust against damaged files or missing plugins. * Use zlib for compression in the rack saving/loading code, as libxml2 often isn't built with compression support these days. If you built the previous release of JACK Rack against a recent libxml2, you won't have been able to open old compressed rack files; you can now. * Dependencies: make libxml2 and zlib mandatory, use pkg-config to find lrdf like the other libraries, and link with libm and libdl (based on patches from James Morris). * Add support for jack-session (implemented by Torben Holm, plus a fix by Peter Nelson). * Move the repository from CVS to Git. * Fix bugs in MIDI controls (patch from Peter Nelson). * Add a Czech translation (patch from Pavel Fric). * Update the Russian translation (patch from Alexandre Prokoudine). * Check for an appropriate GTK+ version (reported by Steven Chamberlain). If you encounter any problems, or if you've got any further patches sitting around that I didn't find when trawling for them, please get in touch with me. Thanks!

[LAU] Club Sandwich Party (Turkey Burger Remix)

by Brandon Hale

Hello all, I'm not sure if I already shared this here, but last year I worked on this community album <https://abstractionmusic.bandcamp.com/album/club-sandwich-party>. The premise of the album is remix/rearrange this <https://abstractionmusic.bandcamp.com/track/club-sandwich-party-2> song. The stems were given to us to use or not use. I had a feeling a lot of the artists working on the album were going to do something upbeat, so I tried to make something a bit more laid back. I decided to do my first impulse tracker module using schism tracker. I wasn't new to trackers, but it was the first time making a full song in schism tracker. I was heavily inspired by Mazedude (mainly <https://www.mazedude.com/remixes/dead-raggening> this track) (and even got advice from Mazedude) and music from the PSX. Anyways, you can listen and watch the track here <https://youtu.be/1A60s8n-SD4?si=DQ_XabEdJz7rBJWu>. You can also download the .it module here <https://modarchive.org/index.php?request=view_by_moduleid&query=207539>. Let me know what you think if you're interested. Brandon Hale
