[LAD] Best practice for sharing complex data structures with a jack callback function

by Andres Cabrera

Hi all, The long title says it all... =) I want to pass some data generated from real-time audio analysis to the main program (only in that direction, i.e. only the jack callback writes to the structures). Are there synchronization issues involved? Can I use a C++ object for this, or is that an absolute no,no? I'm virtually a newbie in programming, so any tips, or pointers to code is very appreciated. Thanks very much, Andrés

[LAD] [ANN] Aqualung 0.9beta8 released

by Tom Szilagyi

The authors are proud to announce the release of Aqualung 0.9beta8. Aqualung is an advanced music player originally targeted at GNU/Linux, today also running on other operating systems such as FreeBSD and MS Windows. We are striving to create one of the finest music players available, with respect to sound quality, stability, features and ease of use. This release is the latest in a series of beta releases on our way to the future stable release of Aqualung 1.0, which is anticipated to be released at the end of this year. The current release adds support for internet radio and tabbed playlists, also containing several smaller improvements and important bugfixes. The ChangeLog for this release is listed below. Homepage: http://aqualung.sf.net Enjoy, Tom 2007-07-07 Tom Szilagyi <tszilagyi at users dot sourceforge dot net> * Aqualung 0.9beta8 http://aqualung.sf.net This is a major release bringing significant new functionality and many important fixes. All users are encouraged to upgrade. Major additions: * Support for internet radio streams using Ogg Vorbis and MP3 audio encoding. * Tabbed playlist support, very similar in concept to the tabbed browsing feature of Firefox. Smaller fixes, rewrites and additions have been also done, particularly to the following areas: * Cut/copy/paste functionality implemented in playlist. Works with the usual Ctrl-X/C/V key combinations. * MPEG decoder: more robust in case of corrupt UBR files. * Command-line local and remote file loading. * M3U and PLS parsers. * HTTP proxy handling. * RVA handling: now supports setting a default value for unmeasured tracks. * Icons and Documentation. * Added Italian translation.

[LAD] Updates and new stuff

by Fons Adriaensen

Hello all, Some updates and new things on my webpages. First official release of jconv. Jconv is a command line jack client performing FFT-based convolution using a mix of up to five partition sizes, small ones at the start of the IR, and building up to the optimum size further on. It allows zero-delay convolution with moderate CPU load. Jconv uses the multi-threaded convolution engine developed for use in Aella, a convolution engine optimised for reverb processing that is nearing completion. Main features of jconv: - Any convolution matrix up 64 by 64, as long as your CPU(s) can take it. - Allows to trade off processing delay to CPU load, and remains efficient even when configured for zero delay. - Reads the same config files as Jace which it will eventually replace. The beta version released two months ago to some volunteers contained a bug discovered and patched by Martin Rumori. It did not affect configurations using independent 1-to-1 convolutions, only matrix operations. Update of Ambdec Some small changes and bugfixes. The configuration format now also permits the use of mixed-order de- coders (2nd order horizontal, 1st order vertical). Manual updated. TetraProc / TetraCal. Both are ready and have been used for real Ambisonic recordings, but release of TetraCal awaits a required update of Aliki, and completion of the manual that describes the calibration procedure. If you want to use Core Sound's TetraMic with TetraProc this is possible today. I signed an NDA with Core Sound giving me access to the impulse response measurements performed by Core Sound on each mic. Given the serial number, I can process these using TetraCal and provide a matching config file for TetraProc. You can see some examples of this on the updated screenshots page for TetraProc. As usual: <www.kokkinizita.net/linuxaudio> Ciao, -- FA Follie! Follie! Delirio vano è questo !

[LAD] [ANN] Qsynth 0.3.0 (unstable-qt4) has been released!

by Rui Nuno Capela

Hi everyone, Qsynth 0.3.0 is now out for you to try and guess what? This marks the point of no return to the aging Qt3 framework. Yes, Qt4 migration was complete. Hints from the change-log might be shallow, but nevertheless: - Qt4 migration has comenced and is now complete. Care must be taken with this new configuration file and location: this release starts a new one from scratch and won't reuse any of the previous existing ones, although cut and paste might help if you know what you'll be doing :) - Application icon is now installed to ${prefix}/share/pixmaps; application desktop entry file is now included in installation; spec file (RPM) is now a bit more openSUSE compliant; initial debianization. - Default font option names were adjusted to "Sans Serif" and "Monospace", wherever available. - The "keep child windows always on top" option is not set as default anymore, because window focus behavior gets tricky on some desktop environments (eg. Mac OS X, Gnome). - Autoconf (configure) scripting gets an update. Good grief. All this is rteadily available from the usual place: http://qsynth.sourceforge.net http://sourceforge.net/projects/qsynth Cheers && Enjoy & -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

[LAD] [ANN] QjackCtl 0.2.23 released!

by Rui Nuno Capela

Hi everyone, Not much to say, but an apologise: QjackCtl 0.2.23 has been released and is the one first ever introducing explicit JACK MIDI support (JACK >= 0.107.0). The version minor number did not bump as promised. Fact is I'm making that reservation for the coming and ever nearer Qt4 migration. So near that it will crash land around now sooner than after ;) The change-log says all the lesser bits too: - JACK MIDI support is now being introduced. Connections window now has a brand new MIDI tab, the older being renamed to ALSA, as for the ALSA/MIDI sequencer conveniency. The server settings now include the MIDI driver setup option (ALSA backend only). - Application icon is now installed to ${prefix}/share/pixmaps; application desktop entry file is now included in installation; spec file (RPM) is now a bit more openSUSE compliant; initial debianization. - Invalidation of the JACK client handle is now forced right on jack_shutdown notification, preventing a most probable fatal crash due to jack_deactivate and/or jack_client_close being called after the jack_watchdog kicks in. - Default font option names were adjusted to "Sans Serif" and "Monospace", wherever available. - The "keep child windows always on top" option is not set as default anymore, because window focus behavior gets tricky on some desktop environments (eg. Mac OS X, Gnome). - Autoconf (configure) scripting gets an update. Of course, official source tarball is made available from the project site: http://qjackctl.sourceforge.net http://sourceforge.net/projects/qjackctl Enjoy, as always :) -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org
