Ubuntu Studio 9.04

by Eric Hedekar

Ubuntu Studio is a multimedia editing/creation flavor of Ubuntu, built for the GNU/Linux audio, video, and graphics enthusiast or professional. The Ubuntu Studio team is proud to announce its fifth release: Ubuntu Studio 9.04. With this release, which you can download in a 1.2GB DVD, Ubuntu Studio offers a pre-made selection of packages, targeted at audio, video and graphics users. Ubuntu Studio greatly simplifies the creation of Linux-based multimedia workstations. For Ubuntu Studio 9.04 we have continued to update packages and fix critical bugs to better the Ubuntu Studio user experience. We are happy to announce the real time kernel will be installed by default in Ubuntu Studio in this release, if the audio task is selected. We have tested it heavily and are happy with it's performance in audio environments. The art has had a cool facelift. The gtk theme has been improved staying in the 'Studio' style. Plus the gdm theme has been switched to some great new eyecandy. New applications included: * FFADO firewire soundcard drivers * Calf audio plugins * LMMS (updated and included in the meta packages) Features/Fixes/Improvements: * Heavily tested 2.6.28 realtime kernel for low-latency audio work * Jack Connection Kit upgraded to 0.116.1 (a major improvement) * Ardour upgraded to 2.7.1 * Fresh ubuntustudio-looks improvements * Addition to Ubuntu Studio Controls to allow users to maintain o Ctr+Alt+Backspace behavior See the Ubuntu release notes for other non Ubuntu Studio specific changes. See http://calf.sourceforge.net/ for more information about CALF. As our wiki page at https://wiki.ubuntu.com/UbuntuStudio states, "our aim is to make it more accessible for new users to get into the tools that GNU/Linux has to offer for multimedia creation and production. We also want to spotlight what's out there, and show users tools they might not know to exist." Thanks to all who helped in Ubuntu Studio 9.04's creation!

LAC 2009 videos available

by Jörn Nettingsmeier

hi everyone! the videos from lac 2009 are being made available at http://lad.linuxaudio.org/events/2009_cdm/videos/ . most of the footage is there - the missing stuff will follow in a few days as florian (aka faberman) gets home from a production in italy and finds time to encode the rest. the video quality this year is quite stunning - thanks to the theora team for huge improvements in efficiency and quality. if you are a video person and haven't upgraded to the thusnelda branch encoder, do it NOW (before even going for a coffee). then hit #theora on freenode.net and sign hymns of praise until they kick you out. you will note that the videos are raw - they could use trimming some talks consist of several fragments that need concatenating, but due to some stream problems they caused oggCat to barf, even though every single fragment plays ok. your help is appreciated - get in touch with me off-list or via l-a-d if you have worked on the stuff and would like to upload your improved version. best regards, jörn

Rivendell v1.4.0

by Fred Gleason

On behalf of the entire Rivendell development team, I'm pleased to announce the release of Rivendell v1.4.0. Rivendell is a full-featured radio automation system targeted for use in professional broadcast environments. It is available under the GNU General Public License. Changes in this release include (from the NEWS file): *** snip snip *** Changes: Unique Cart Titles. It is now possible to configure the system (in RDAdmin->SystemSettings) to disallow duplicate cart titles. RDAirPlay Full Log Controls. New controls have been added to the Full Log widget in RDAirPlay to allow the head and tail of carts to be auditioned, as well as a set of log runtime counters. To make these controls visible, it is necessary to check the 'Show Extra Buttons/Counters' box in RDAdmin->ManageHosts->RDAirPlay. RDCastManager Enhancements. An Podcast episode filter has been added. Also added to the online version is the ability to audition each episode by downloading the media file to the local system. Bugfixes. See the ChangeLog for details. Database Update: This version of Rivendell uses database schema version 177, and will automatically upgrade any earlier versions. To see the current schema version prior to upgrade, see RDAdmin->SystemInfo. As always, be sure to run RDAdmin immediately after upgrading to allow any necessary changes to the database schema to be applied. *** snip snip *** Further information, screenshots and download links are available at: http://www.rivendellaudio.org/ Cheers! |-------------------------------------------------------------------------| | Frederick F.

Jack2 on DROPS/L4 (Diploma thesis) | towards a truly real-time capable FOSS audio distribution

by micu

Dear Linux Audio Developers, as indicated by Stéphane in his presentation [1] he gave at LAC2009 today, I finally handed in my diploma thesis, which I announced here [2]. You can download the full text of the thesis here: <http://www1.inf.tu-dresden.de/~s3418892/diplom.pdf> [3]. If you want to take a glimpse at the code, you can get a (still very dirty) snapshot of the code here [4]. The abstract of the thesis: > Several available free software audio solutions were analyzed, and > Jackdmp—a C++ reimplementation of the renowned JACK Audio Connection > Kit—was selected as the most appropriate solution for a real-time audio > architecture on DROPS. The JACK sound architecture provides the lowest > processing latency possible on a desktop computer for a given set of sound > card parameters. It reduces the latency jitter caused by software to zero > and synchronizes streams at sample accuracy. > A real-time admission scheme for JACK clients is proposed. > The execution time of different typical JACK clients was analyzed with > measurements to validate the assumptions the proposal is based on, > but also to gain further knowledge about their timing behavior. > The measurements showed that the condition set by Paul Davis—the > time to process a client must be a linear function of the buffer size—holds > for all tested clients. > Jackdmp was ported to DROPS. The developed design of the port and its > implementation is documented here. Measurements showed that—although > the real-time performance of the Linux kernel is continously being improved > in the mainline and on special external branches—DROPS can provide a > signaling latency that is two times lower on average than the values that > can be achieved on the same machine running with a low latency patched > Linux kernel. Thus, it can be stated that DROPS is well-suited for > real-time audio processing and that the pursued path to use it as the > foundation of a truly real-time capable audio workstation should be > followed. As of the project's future: I will try to get the ALSA driver and the connection with L4Linux working until the presentation of the project (no date set so far, but probably in 2--4 weeks or so). If all works well, we will consider releasing a demo disc and / or a Youtube demonstration for interested developers and power users of the system then. And then we'll see :). Kind regards --- and those of you who are in Parma: Have an interesting conference and a great time in Italy! ---, micu =============================================================== [1]<http://linuxaudio.de/lac2009/JACK2_LAC_2009_slides.pdf> [2]<http://lists.linuxaudio.org/pipermail/linux-audio-dev/2008-July/021384.html> [3]<http://www1.inf.tu-dresden.de/~s3418892/diplom.pdf> // This is only a temporal location, I will inform you about the final location here as soon as the document is published there.

Announcing jMax Phoenix : Call for developers

by Maurizio De Cecco

[Feel free to forward this announce anywhere you find appropriate] The reports of the jMax death have been greatly exaggerated. Free software never dies, it just sleeps for some time. Almost nine years after the release of the project under a free license, and six years after the end of the developments by the institution that created it, some of the original project developers decided to revive it from its ashes: jMax Phoenix was born. JMax is a community project, not controlled by a single institution; it was Started from some of the original jMax developers in the summer of 2008. The project priorities are to give jMax a modern User interface, to integrate it into the modern Linux audio environment, and, last but not least, scalability. Detailed plans for the projects are presented in these days at the Linux audio conference 2009 in Parma. Check the proceedings for more information. We are looking for, core developers (C, Objective C, Java, Swing), object developers (DSP, Control), porevelopers to port existing libraries, testers and early users, and a graphic designer. Please not that the jMax Phoenix project is a fork of the original code base and cvs. For those who know the jMax history, jMax Phoenix started from jMax 2.4.5. Later developments will be backported if judged interesting. The developments are today focused on the user interface: more than one third of the code has been rewritten, and the rest heavily modified to provide an interface aligned with modern standards. The project home page is http://www.jmax-phoenix.org, where you can find the main page and a wiki including user documentation and design documents. The project team can be contacted at contact(a)jmax-phoenix.org. The project sources and mailing lists are hosted by sourceforge, at http://sourceforge.net/projects/jmax-phoenix/; please, join the developers mailing list to follows the project evolutions, give your opinions or express your needs. You’ll find snapshot binary releases on the sourceforge site; they are versioned using the subversion revision number; these snapshots are not yet supposed to be stable or fully functional, but they currently give a pretty good idea of the evolution of the user interface. The user documentation in the wiki will be kept consistent with the last snapshot released. JMax Phoenix is release under the original jMax license, GPL with an exception for loaded package, and the is copyrighted either by Maurizio De Cecco, François Dechelle and Enzo Maggi, or by Ircam, or by both set of authors. Hoping to see you on the jMax mailing list. The project team (Maurizio, François and Enzo). -- Music: http://www.myspace.com/mauriziodececco Blog: http://maurizio.dececco.name/ Software: http://www.jmax-phoenix.org/
