[paul@linuxaudiosystems.com: [Jack-Devel] jackaudio.org website shut down due to hacking]

by Adrian Knoth

Hi! I'm sure there must be users out there who are familiar with web stuff and are burning to help their favourite inter-application audio framework. ;) Step up, please. PS: There is also a semi-complete move to GH-pages. If your're familiar with github, you could be the ideal volunteer. ;) Cheers ----- Forwarded message from Paul Davis <paul(a)linuxaudiosystems.com> ----- Date: Fri, 30 May 2014 11:56:02 -0400 From: Paul Davis <paul(a)linuxaudiosystems.com> To: JACK <jack-devel(a)lists.jackaudio.org> Subject: [Jack-Devel] jackaudio.org website shut down due to hacking The malicious conscience-free leeches who push pharmaceutical spam managed to hack into jackaudio.org in a very deep way. They had full access to everything including the ability to fiddle with MySQL tables (some of them). I don't consider any part of the Drupal site safe, so I have shut it down and replaced it with a single static index.html file. The source tarballs for JACK1 were uncorrupted (probably JACK2 also - waiting for confirmation from Stephane on this), and I have put up a new link to the most recent. I also referenced github for the source code repository and issue tracker. As someone said on IRC today " It's a shame the lead dev has to waste his time coding, answering user questions AND fixing drupal backdoors " If someone else wants to volunteer to resurrect the roughly 60 pages of content that were at jackaudio.org (and realistically, it is probably more like 20 of real stuff that is needed), get in touch. I can give you full access to everything you will need. _______________________________________________ Jack-Devel mailing list Jack-Devel(a)lists.jackaudio.org http://lists.jackaudio.org/listinfo.cgi/jack-devel-jackaudio.org ----- End forwarded message ----- -- mail: adi(a)thur.de http://adi.thur.de PGP/GPG: key via keyserver

LAC'14 video archive

by Robin Gareus

Hi all, The video recordings of the LAC'14 presentations have just been uploaded to the conference website and are now directly linked from the archive: http://lac.linuxaudio.org/2014/program There are still a three videos missing and the workshop videos are also yet to come. Currently they are also only available as vp8/vorbis/webm (sorry IE and Safari users). But since it has been quite a while already, we decided to not hold back the release of these already finished videos any further. Once the collection is complete, we will provide a .torrent. Meanwhile, for those who prefer to download the videos incrementally, they are accessible via rsync://linuxaudio.org/ [1]. Many thanks for Frank and Moritz to get those done in really outstanding quality this year. Kudos to the complete stream-team. enjoy, robin - for the LAC'14 team [1] example to get the 720p versions: rsync -Pa --exclude "*360p.webm" \ rsync://linuxaudio.org/lac2014/ \ lac2014/

Creative Music Coding lab #12 in Amsterdam

by nescivi

Calling all ChucK’ers, SuperColliders, Max and PureData patchers, CSounders, Fluxites, Overtoners, and all other tongues of creative coders. We welcome you to attend the fifth edition of the Creative Music Coding lab at STEIM. The CMC lab is an autonomous zone to try out sonic experiments as a group. And an opportunity to leverage the expertise of the group in realizing new artistic tools and processes through the medium of code. Many of the founding members of the group are indeed experts in their favorite languages, but we come from all technical levels of proficiency and enjoy helping one-another out. http://steim.org/event/creative-music-coding-lab-12/ DETAILS DATE: Tuesday, 24 June 2014 TIME: 19:30 ENTRY: FREE LOCATION: STEIM Concert Space, Utrechtsedwarsstraat 134 Amsterdam What ARE the goals for the lab? * a place for creative music coders to show work in progress, regardless of programming language or platform * a place to discuss and question techniques with fellow computer musicians * an informal stage for playing with others, livecoding sessions, jamming, and other fun experiments * an opportunity to meet like-minded artists, share talents, and start new collaborations * an opportunity to be exposed to new languages and improve cross-language fluency * a way to discover lesser known and emerging creative programming paradigms * a place to to discuss interconnections between programming environments * an environment for discussions on cultural contexts surrounding coding in the arts We encourage members of the group to use this as a platform for exploring ways in which we might be able to create and play together. Proposals for creative group investigations of hardware, software, and coding as process are welcome. As always, entry is free, tea and coffee will be provided.

Strange inconsistency in jack frame time

by Fons Adriaensen

Hello all, While putting the finishing touches on zita-njbridge and doing a lot of testing I stumbled on this strange behaviour of jack's frame time. Let F(i) be the frame time corresponding to the start of period 'i', and U(i) the corresponding microseconds time. If jack for whatever reason skips some periods, then one would expect the difference of F(i) and U(i) to be consistent. They are in some but not in all cases. This is the output from a test. When the frame time makes an unexpected jump, it prints the difference of F, the difference in U converted to frames, and the difference of these two. Period size is 256 frames. dframes = 768 769.0 1.0 dframes = 1024 1322.8 298.8 dframes = 1024 1024.7 0.7 dframes = 768 1067.3 299.3 dframes = 1024 1023.7 -0.3 dframes = 768 1068.5 300.5 dframes = 768 769.2 1.2 dframes = 768 1067.3 299.3 dframes = 1024 1023.9 -0.1 dframes = 1024 1323.1 299.1 dframes = 768 768.2 0.2 dframes = 768 1066.7 298.7 The cases where F and U match are due to starting another client (designed to be 'heavy'), those where F and U do not match occur when the same client is terminated (using ^C). The error for those is consistently a full period plus around 4333 frames. So it seems that the frame time is not a reliable method to determine how many frames have been lost. Using jack1, 0.124.1 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)

by Rui Nuno Capela

Headless finally! QmidiNet 0.2.0 is out! all that is to say that it may now run without the GUI, eg. qmidinet --no-gui QmidiNet [1] is a MIDI network gateway application that sends and receives MIDI data (ALSA-MIDI and JACK-MIDI) over the network, using UDP/IP multicast. Inspired by multimidicast [2] and designed to be compatible with ipMIDI [3] for Windows.

FaustLive is released !

by Stéphane Letz

GRAME is happy to announce the official release of FaustLive. FaustLive is an advanced self-contained prototyping environment for the Faust programming language with an ultra-short edit-compile-run cycle. Thanks to its fully embedded compilation chain, FaustLive is simple to install and doesn't require any external compiler, development toolchain or SDK to run. FaustLive is the ideal tool for fast prototyping. Faust programs can be compiled and run on the fly by simple drag and drop. They can even be edited and recompiled while running without sound interruption or Jack disconnection. 1) Dynamic Compilation : On FaustLive’s windows you can drop your Faust code as a file, a string or a url. The code will be dynamically compiled and executed. You can then choose to edit your code. It will be opened in the default editor for .dsp files (FOLLOW THE README TO CONFIGURE FILE ASSOCIATION). The application will be automatically recompiled, every time you save your document. A crossfade is calculated between two relaying applications in a window to avoid brutal sound interruptions. 2) Audio Drivers : Depending on your Operation System, you will have different drivers available: On OSX : Coreaudio, Jack and NetJack On Linux : Jack and NetJack On Windows : Portaudio You can then dynamically switch from one to another in FaustLive’s preferences. 3) Export Your DSP : Exporting your DSP as plugins is easy, thanks to FaustWeb, compilation service. In FaustLive’s export menu, you can find every platform and architecture that Faust can target. As you choose your target, your code is sent to FaustWeb and you receive the requested binary in exchange. 4) Save Snapshots : If you create a configuration you like, you can save it as a Snapshot. The state of FaustLive will be saved (running applications, Jack connections, interface parameters, …). Later on, you will be able to whether : - recall the snapshot : closing any running application to restore the saved state - import the snapshot : adding the saved state to the current state 5) Remote Control Interfaces (only on Linux and OSX for now) : In the Windows Option toolBar, you can open a UDP port for OSC control or a TCP port for HTTP control. Moreover, the HTLM interface can be accessed through a QrCode that you can create from «View QrCode » in the menu « Window ».

New MOD Website

by Gianfranco Ceccolini

Hi everybody Still recovering from the LAC2014 trip but already with news, here’s the link to our new website (including english version) www.portalmod.com The video that was shown at the MOD presentation is right in the frontpage. Even better, the plugin library can now be navigated in the same way as in the MODs interface. On top of it, there’s a dashboard section where visitors can try the interface without audio. Hope you all enjoy. Cheers Gianfranco Ceccolini

jack / sched_deadline

by Leonardo Gabrielli

Hi Tim, that's an interesting point. Next week I'll be in Pisa, Italy, for a workshop held by some of the SCHED_DEADLINE guys. I'm not a serious dev but I do research and I'll be glad to evaluate the benefit of SCHED_DEADLINE for audio and jack, compared to SCHED_FIFO.
