[LAU] [ANN] Vee One Suite 0.7.1 - A seventh-bis beta release

by Rui Nuno Capela

Hello again, The 'Vee One Suite' aka. 'the gang of three old-school' software instruments, featuring synthv1 [1], as one polyphonic synthesizer, samplv1 [2], a polyphonic sampler and drumkv1 [3], as one drum-kit sampler, which is getting a small but pertinent bug-fix, are all making up for the so called 'Summer'15 release frenzy (extended edition;))'. All made available in dual form: - a pure stand-alone JACK [4] client with JACK-session, NSM [5] (Non Session management) and both JACK MIDI and ALSA [6] MIDI input support; - a LV2 [7] instrument plug-in. Change-log: - Fixed a recent bug/mistake that was causing a complete reset/revert of all element parameters to prior values upon loading an element sample file. (applies to drumkv1 [3] only) - Improved Qt4 vs. Qt5 configure builds (via qmake). The Vee One Suite are free and open-source Linux Audio [9] software, distributed under the terms of the GNU General Public License (GPL) [8] version 2 or later. And here they go again! **synthv1 - an old-school polyphonic synthesizer [1]** synthv1 0.7.1 (seventh-bis official beta) is released! synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.

[LAU] project "droning" is back

by Louigi Verona

Hey everyone! After an almost 2 year break I am back to working on my life-long project "droning" <http://www.disc-shelf.com/droning/>. *New releases* The last tune has been 246 far too long and I am happy to present you two new tunes. droning247 <http://www.disc-shelf.com/droning/droning247.ogg> (ogg) droning248 <http://www.disc-shelf.com/droning/droning248.ogg> (ogg) For those of you who would like to support my work, you can get flac release of droning248 from Bandcamp. droning248 on Bandcamp <https://louigi.bandcamp.com/album/droning248> *Web presence* My website which was louigiverona.ru is now offline, but I will get it online hopefully within 2-3 months. All my projects, including Linux Audio articles, releases and such will again be available, albeit not on the .ru domain. I will announce this separately. Additionally, project "droning" will finally be getting a separate website, dedicated wholly to the endeavor. Big thanks for following and supporting the project! -- Louigi Verona http://www.disc-shelf.com/droning/ <http://www.louigiverona.ru/>

[LAU] updates

by Fons Adriaensen

Some updates on <http://kokkinizita.linuxaudio.org/linuxaudio/downloads/index.html> zita-ajbridge-0.6.0 - Added -S option, disables resampling but of course requires word-clock sync. - Auto selection of best resampler filter lenght. - Cleanup and bug fixes. zita-mu1-0.2.2 - Bugfix: will now exit when zombified or when jackd terminates. - Added proper license headers and GPL3 copy. I also completely replaced the code in Jack1 that calculates the proper running order of clients. The previous algorithm failed to do this in some cases. It could not be 'fixed' easily as it was basically using the wrong algorithm. Affected files are modified: include/engine.h modified: include/internal.h modified: jackd/clientengine.c modified: jackd/clientengine.h modified: jackd/engine.c There seems to be no interest from the Jack devs, but if anybody wants to test this I can either provide the modified files or a patch against git commit 5af5815c47630b77cc71c91a460f8aa398017cf7 (current HEAD). Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities. (Cory Doctorow)

I have QT 5 and QLoud has some clash between QT4 and 5. (I'm on Ubuntu Studio 14.04, plus I do dev work in PYQT5) Looks like QSpeaker requires QT4 as well. Apparently QAppliction is now in QWidgets. I poked around the web and tried several "fixes" proposed in several threads, no luck.

[LAU] [ANN] A website for pre-sets, soundfonts, and more

by lucas z

Hey everyone, this is a project I've been working on for some months now and now I think it's ready for some beta testing. https://musical-artifacts.com/ is a place to collect free 'musical artifacts', that is, pre-sets, configuration files, soundfonts, etc. make them searchable and taggable and give credit to authors. For example here are some soundfonts, zyn pre-sets and guitarix tones: https://musical-artifacts.com/artifacts?tags=soundfont https://musical-artifacts.com/artifacts?apps=guitarix https://musical-artifacts.com/artifacts?apps=zynaddsubfx I've started populating the application with some artifacts and will continue doing so in the future. Also the application is in BETA right, so new features are coming and some bugs are to be expected! You can look at the source, contribute or file bugs via github https://github.com/lfzawacki/musical-artifacts That's it!

[LAU] Music made with Linux - Second & First

by F. Silvain

Hey hey everyone, I'd like to announce this new track. Composed and recorded by J.P.C. with guitars by J. Bausch. Mixing and mastering by me. I believe this was fully made in Linux using Nama from start to finish. Including a host of plugins and soft- and hardware instruments. http://freeshell.de/~silvain/audio/second_and_first.ogg I'd appreciate feedback, if you have it. :) Ta-ta ---- Ffanci * Homepage: https://freeshell.de/~silvain * Twitter: http://twitter.com/ffanci_silvain * GitHub: https://github.com/fsilvain

[LAU] Linux/JACK app for room eq / speaker design-analysis

by Mac

Hi, After spending time trying to get RoomEqWizard (REW) to use Jack effectively and simply getting frustrated I'm looking for other tools. (REW is a nice tool but it doesn't support JACK natively and I tried fooling it with alsa etc., but I think PulseAudio was getting in the way.) I ended up using jaaa and japa from Fons Adriensen which work great. But, I'd like to be able to save the display. I suppose I could use screen shots for each test and that would be fine. But, I thought I'd see if anyone knows a Linux tool that can do waterfall plots, frequency response, etc. Maybe even distortion. Any recommendations? Regards, Mac

[LAU] RPi based audio metering device (EBU R128 etc.)

by laulau

Hello List, i am new to this list so forgive if this has been discussed before - a quick search of the archives didnt reveal anything relevant. I am trying to build an audio metering device (stereo only for now), with the purpose of monitoring my video editing system. Right now this is based on a RPi running Arch Linux ARM. As the window manager i decided for i3 tiling WM. The RPi has a 7" 800x480 Touchscreen connected (to be able to reset EBU R128 measuring Keyboard and Mouse-less). As a soundcard i am using the Behringer U-Control UCA222, connected to a Samson C-Control as the audio splitter for speaker monitoring etc. As the software i am playing with the ebumeter, yass & jaaa from Kokkini Zita (http://kokkinizita.linuxaudio.org/linuxaudio/). I installed the jackmeterbridge tools as well. I am still trying to figure out what software will be useful in "real life" situation, meaning what is the RPi capable of handling CPU wise (jaaa pushed it to its limits naturally). - So i wondering, has anyone done something similar before and can share his / her experiences? - Are there other software tools that i have missed that would be worth looking at? - Especially screen estate is a problem with a 800x480 pixel screen. Jass fits barely, ebumeter is super small etc. Is there a way to scale fixed width tools differently to make a nicer screen layout? best, t.

[LAU] Loading soundfonts from a script (LS or FluidSynth)

by F. Silvain

Hey hey everyone, I need to load a soundfont (SF2) from a script. I've tried with LinuxSampler and it worked, but I only got sound in the first channel (LinuxSampler:0). In Fluidsynth I get stereo output, but I haven't found a way to select the desired patch from the soundfont through the commandline options. Using -f with stdin shuts Fluidsynth down immediately. Any idea to solve either problem? Ta-ta ---- Ffanci * Homepage: https://freeshell.de/~silvain * Twitter: http://twitter.com/ffanci_silvain * GitHub: https://github.com/fsilvain

[LAU] [OTish] FFT and state-space representation

by F. Silvain

Hey hey everyone, I'm currently studying for one of my electircal engineering causes, which deals mainly with state-space representation of linear, time-invariant systems. But I have still failed to grasp the practical meaning of some of the values involved. I thought a practical example might help and I've turned to convolution, since that is a subject I am slightly familiar with. Could someone perhaps help me here? A link to such an example or explanatory article in LaTex form could be sufficient. I'm sorry to misuse this list for such a question. Thank you for reading!
