Hello, a new version of the LV2 plugin B.Choppr is released a few days ago. B.Choppr is an audio stream chopping LV2 plugin and the official successor of B.Slizr. The new version contains an important fix of a bug that limited the use of this plugin. What's new: * Bugfix uninitialized markers upon GUI start that resulted in weird chopping effects in v1.2.x * Bypass * Dry / wet mixing Project page: https://github.com/sjaehn/BChoppr Download: https://github.com/sjaehn/BChoppr/releases Instructions: https://github.com/sjaehn/BChoppr/blob/master/README.md Try, enjoy and have fun Sven Jaehnichen

linuxaudio.org maintenance 2020-03-29

by Jeremy Jongepier

Dear all, Today I'd like to perform maintenance on the linuxaudio.org web server around 20:00 CEST. Maintenance comprises moving from GlusterFS storage to disk storage in order to improve performance of the web server. GlusterFS seemed promising but through time we came to realize it's not optimal for our situation. Maintenance will take approx. 3 hours. During that period the sites hosted on the web server won't be reachable as I'd like to shut down all services before doing a final rsync. Thanks for your understanding. Best regards, Jeremy

[ANN] Qtractor 0.9.13 - A QStuff* Spring'20 Release batch #3

by Rui Nuno Capela

Greetings, just one third time! Qtractor 0.9.13 (spring'20) is released! Change-log: - All meters background color are now customize-able (cf. View/Options.../Display/Meters, color level "Back"). - Automatic mixer grid layout (multi-row) is now in effect permanently--being an option no more. - Always show plugins and meters on track list/left pane as permanent standard now. - LV2 UI Request-value feature/interface support has been implemented. - Audio output monitoring meters are now shown/hidden auto-magically on MIDI tracks and/or buses--no need for some user preference option anymore (ie. View/Options.../Plugins/Instruments/Show audio output monitoring meters, is now gone). - Default track height has been slightly increased. - Track / Duplicate Track... now also takes a MIDI track's audio meters setting into account. - VST3 plug-in support introduced. (EXPERIMENTAL) - Fixed first bar/measure position drawing on the time-scale/grid across time-signature changes on the MIDI clip editor (aka. piano-roll) (hopefully fixing issue #245). - Plugins and meters on track list/left pane, are now being set on as default--maybe going stapled in some near future ;) - Make man page compression reproducible (after request by Jelle van der Waa, while on the Vee-Ones, thanks). - Avoid resetting top or left position when zooming with mouse pointer is in main tracks or MIDI clip editor (piano-roll) views. - Make libaubio a build dependency on Debian/Ubuntu; also fix cross-build check to sizeof(float). - Bumped copyright headers into the New Year (2020). 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.

New AMB plugins

by Fons Adriaensen

Hello all, Two new sets of AMB plugins are available at <http://kokkinizita.linuxaudio.org/linuxaudio/downloads/index.html> AMB1-plugins: First order panners, Z-axis rotation, and dominance. HOA3-plugins: Third order panners, Z-axis rotation, converters for SN3D to/from N3D and FuMa. See the README for details. All of them now use the 'Ambix' format and gains (except of course the convertors at the non-SN3D side). Ambix format uses ACN channel order, as does Ambdec. So e.g. Ardour master outputs will be in the same order as Ambdec inputs, but channel numbers are offset by 1, for example: Ardour master Ambdec input ---------------------------- 1 in.0 (W) 2 in.1 (Y) 3 in.2 (Z) 4 in.3 (X) If you use these with Ambdec, don't forget to check the 'Input scaling' in the configuration dialog. This should be set to 'SN3D'. If necessary, change, apply and optionally save the preset. -- FA

pajackconnect v1.0 released

by Hermann Meyer

I just noticed to day that I never have done a proper release for pajackconnect. I use it since 3 years every day, mostly without notice it at all. Today I receive a contribution which fix some (small, but well worth to fix) issues, that reminds me to go and make a release. https://github.com/brummer10/pajackconnect/releases/tag/v1.0 From the README: > Make JACK Work With PulseAudio > > This script is intended to be invoked via QjackCtl to start up and > shut down JACK on a system running PulseAudio. It handles the > necessary setup to make the two work together, so PulseAudio clients > get transparently routed through JACK while the latter is running, or > if pulseaudio is suspend by pasuspender, do nothing > > Usage: in QjackCtl’s Settings window, in the “Options” tab, enter the > command > > pajackconnect start & > > in the field labelled “Execute script after Startup”, and put > > pajackconnect stop & > > in the field labelled “Execute script on Shutdown”. > > pajackconnect reset & > > in the field labelled “Execute script after Shutdown”. > > for use jack without pulseaudio, add in Qjackctl setting window in the > serverpath field 'pasuspender -- ' before 'jackd', save settings as > "No Pulse" for example. Remove 'pasuspender -- ', and save settings as > 'Pulse'. Now you can select from the Qjackctl setting window, if you > would start jack with or without pulse. > > To make it work after suspend, the file resume-fix-pulseaudio.service > needs to be installed and enabled. If you use the debian package, the > package installer handle that for you. >

jack_set_port_connect_callback

by Sigmund Gudvangen

It turns out it was just a daft oversight: the client had terminated prematurely. So now it is working. Sigmund.

jack_set_port_connect_callback

by Sigmund Gudvangen

Hi, I am trying to detect port connection and deconnection, using a callback function, thus: void JackPortInfo::connectionJackCallback(jack_port_id_t a, jack_port_id_t b, int connect, void* arg) // deceard as static { qDebug() << "JackPortInfo::connectionJackCallback()"; } bool JackPortInfo::initPortCallback() { int check; if ((check = jack_set_port_connect_callback(client, connectionJackCallback, this))) qDebug() << "check: " << check; } I call initPortCallback() just after jack_client_open(...) and it returns NULL, so this part looks OK. However, connectionJackCallback is not called when I start/stop Audacity. What am I overlooking? Sigmund.

Berkley DB requirement

by Bruno Vernay

Hi I was wondering why properties do not work in Fedora, but the package does not build with DB. I just wanted to make sure that properties are dependent on Berkley DB. There is no alternative systemd or other things that I would have missed that would make properties to work ? (and by the way if there is an introduction on how to setup Jack2 in any IDE that would be great.) Thanks Bruno

wiki.linuxaudio.org mostly fixed again

by Jeremy Jongepier

Dear all, The linuxaudio.org wiki is almost fully functional again. It was a real pain to update it to a more recent version and to get the plugins to work again with PHP7. Editing is still a bit of a chore, somehow you don't return to the page after hitting save, but it seems to work. Please check it out and if you have any ideas for improvements or if you run into bugs please let me know. Best, Jeremy
