[LAD] [ANN] QjackCtl 0.3.9 quietly emerges...

by Rui Nuno Capela

Guess what...? the last of the remnants quietly emerges :) QjackCtl 0.3.9 has been released, finally! Website: http://qjackctl.sourceforge.net Project page: http://sourceforge.net/projects/qjackctl Downloads: - source tarball: http://downloads.sourceforge.net/qjackctl/qjackctl-0.3.9.tar.gz - source package (openSUSE 12.1): http://downloads.sourceforge.net/qjackctl/qjackctl-0.3.9-1.rncbc.suse121.sr… - binary packages (openSUSE 12.1): http://downloads.sourceforge.net/qjackctl/qjackctl-0.3.9-1.rncbc.suse121.i5… http://downloads.sourceforge.net/qjackctl/qjackctl-0.3.9-1.rncbc.suse121.x8… Weblog (upstream support): http://www.rncbc.org License: QjackCtl is free, open-source software, distributed under the terms of the GNU General Public License (GPL) version 2 or later. Change-log: - Killing D-BUS controlled JACK server is now made optional, cf. Setup/Misc/Stop JACK audio server on application exit. (a patch by Roland Mas, thanks). - Added include <unistd.h> to shut up gcc 4.7 build failures. - Make(ing) -jN parallel builds now available for the masses. - A mis-quoting bug at the command line argument string may have been crippling the (unmaintained) Windows port since ever, leaving its main function to start jackd dead in the water, belly down :) now hopefully fixed (following a mail transaction with Stephane Letz and Mathias Nagorni, thanks). - Currently a JACK2-only feature, the JACK version string display at the About dialog box, must now be explicitly enabled on configure time (--enable-jack-version). - A new so called "Server Suffix" parameter option appears to rescue on the situations where QjackCtl falls short on extra, exquisite and/or esoteric command line options eg. (net)jack1/2 differences. - Fixed D-Bus Input/Output device parameter settings, filled when either interface is selected for Capture/Playback only. (probable fix for bug #3441860). - Fixed Makefile.in handling of installation directories to the configure script eg. --datadir, --localedir, --mandir. (after an original patch from h3xx, thanks). - Main window is now brought to front and (re)activated when clicking on the system tray icon instead of just hiding it. - Add current xrun count to the system tray icon tooltip, if not zero (after patch #3314633 by Colin Fletcher, thanks). Enjoy && Have fun! -- rncbc aka Rui Nuno Capela

[LAD] New SVN version of LV2:AVW - Crashes Ingen

by Aurélien Leblond

Hi everyone, I posted a new version of the LV2:AVW on the SVN: svn checkout svn://svn.code.sf.net/p/avwlv2/code/trunk avwlv2-code Unfortunately, it is crippled with a bug that I can't for the life of me fix! The scenario is as followed: - Open Ingen - Add one of these plugins - Remove it and Ingen crashes That other scenario would crash it too: - Open Ingen - Add one of these plugins - Add any other plugin (I use MDA) - Remove the MDA plugin, and Ingen crashes. Now, I don't think the issue lies in Ingen as I can add/remove any instances of the MDA plugins for example. But JALV or Ardour don't see to have this issue... I'm really looking for some help guys, because I have been trying to debug that one for few weeks now without much success. Thanks in advance for....anything! Aurélien

Hmm, I might steel your freewheeling and dithering code into jack_capture. :-)

[LAD] First release of jack_export

by Fons Adriaensen

Jack_export is a simple command line app I've been using to do multichannel exports from Ardour2 sessions. Of course A3 provides this OOTB, but I will maintain jack_export to provide (if necessary) formats and options that A3 doesn't or won't support. This release does not include resampling, the sample rate of the exported file will be the current Jack sample rate. To use, proceed as follows: 1. (Optional) In Ardour, create a bus (not a track) named 'export', and containing all the signals you want to export. You can skip this step, in that case you'll have to connect Ardour outputs to jack_export inputs manually after step 2. 2. Run jack_export. See --help for options. The --chan option is mandatory. E.g. jack_export --chan 16 my16channelfile.wav Jack_export will connect to the 'export' bus if it exists, and print Ready ... If you did not create an 'export' bus in Ardour, now connect Ardour outputs to jack_export inputs manually. 3. Do a normal export in Ardour, using some dummy name for the exported file. As soon as Jack goes into freewheeling mode, jack_export will print Recording ... When the export terminates, jack_export will print a completion message reporting the number of seconds recorded. Now available on <http://kokkinizita.linuxaudio.org/linuxaudio/downloads/index.html> 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)

[LAD] IR: LV2 Convolution Reverb and ambisonics

If you use Ardour to create, mix& > produce music, you will most probably want to check out this plugin. It is a great addition Tom, I'm packaging it in Planet CCRMA now. I'm trying to see what is the best way to convert the plugin so that it can deal with first order ambisonics impulse responses. Those are four channels wide (ie: four convolutions, one for each of the four incoming channels - W X Y Z). I managed to get it to work by creating ir-amb.cc, ir-amb_gui.cc, etc, etc. And changing your code to have the required number of ports, etc. It does work, except that my simple minded rewrite breaks down if I try to instantiate a normal IR plugin in addition to the IR-AMB (how I named the "new" plugin). In that case the second instance (order does not matter) bugs out with: (ardour-2.8.12:14284): GLib-GObject-WARNING **: cannot register existing type `IRWaveDisplay' etc (same for IRModeInd and IRMeter, all the gui classes I did not duplicate). I can have multiple instances of either, but not mixed (well, I can, it is just that opening the gui for the second does not work and crashes the rest). Knowing nothing about all the components involved I need some help... I can supply or post the patch if needed (I presume it is some simple gtk thingy I need to add to the code). -- Fernando

[LAD] SMPTE and jackd

by Egor Sanin

Hi folks. I've got a question about SMPTE frames and jack period size. In the "worst case" of 30 frames/second, each frame spans 1/30 seconds. Does that mean that if jackd is called such that (period size)/(rate) > (1/30) seconds, we will drop SMPTE frames? Large period sizes are rare these days, but this is still a possible scenario and I want to understand it properly. Thanks.

[LAD] How do I add threadirqs as a default boot parameter for a linux kernel not editing boot configs?

by Kaj Ailomaa

I've been trying to find some docs on how to get the kernel to boot with the threadirqs by default, and not needing to pass that option manually at boot time (or editing a boot config). Or, any boot option for that matter.. Anyone care to shed some light on this? :)
