[PD-announce] share-mem lib
by Cyrille Henry 10 Jul '13

10 Jul '13

hello, i just did a initial commit of share-mem, a lib dedicated to deal with shared memory. background : pd / pd~ communication is really slow. by example, having a pd~ patch with 8 audio in and 8 out, use about 50% cpu of a recent computer for each process only to deal with audio communication. sending a large array from one process to the other is almost not possible in RT. This really limit pd~ usability. ----- Thanks to share memory, communication between process can be greatly improve. This lib is mainly composed of an external, and few abstraction and examples. Everything look stable, at least on a ubuntu (12.04) and a osX laptop. Implementation follow POSIX standard, so it will unfortunately not work on windows. everything that I need is there, even if lot's more work could be made. I hope to have user feedback before making more development. Cheers Cyrille _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

Where is vanilla's makefile and other stuff located?
by Alexandros Drymonitis 07 Jul '13

07 Jul '13

Hi, I've been trying to install Pd vanilla on Ubuntu 12.04 together with Pd-extended. I think I've created some mess as there are symbolic links pointing at other symbolic links pointing at pd-extended. Even though I thought I hadn't managed to install vanilla, I realised it's sitting in /usr/bin/ as puredata. In /usr/lib/ there is a pd/ directory which includes a doc/ and a extra/ directory, but these two directories have only Gem stuff, no [bonk~] or [fiddle~] or [expr~] (even though I can create all these objects). I have a vanilla version is OS X and in /Applications/Pd-0.44-0 there is the Contents/ directory where all the necessary stuff lies (Resources/extra etc.). Anyone knows where all this stuff is sitting in Ubuntu? Thanks

pd-extended crashes sending data to SSR with tcpclient
by Iain Mott 03 Jul '13

03 Jul '13

Hi list, Pd-extended (Pd-0.43.1 "extended-20120430" compiled 00:31:34 Apr 30 2012) is crashing when I send data to the SoundScape Renderer on Ubuntu 12.04 using tcpclient. I'm using the latest SSR from here: http://spatialaudio.net/ssr/download/ but the crashing occurs with the older version ssr-0.3.4 as well. Once, Pd produced the following error message on crashing, but generally doesn't give any clues: pdsend errorname: >>error writing "sock8": connection reset by peer<< I've been able to simulate the crash with a simplified set up. If anyone can please have a look, I'd be very grateful. The archive is uploaded here: http://reverberant.com/tmp/test.zip To test it, you'd need to unzip the file, enter into the directory the directory with the extracted files, then, assuming the latest SSR is installed and jack is running at 44.1kHz, run: ssr-binaural rei_voz4.asd & in order to launch ssr with a scene. Then, if your pd-extended is not installed as /usr/bin/pd-extended, you'll need to edit the path in startpd.sh to suit. Then run: ./startpd.sh Once Pd is open, first click "localhost" (see yellow region #1) to make the connection with SSR, then wiggle the vertical slider (near yellow region #2) wildly until Pd crashes. At least, that's what happens to me. Some times it may take up to 30 sec or a minute to crash - or not at all. Usually it crashes in less than 15 sec. Pds audio processing does not have to be on for the crash to occur. Can anyone replicate the crash? Suggestions welcome! Cheers, Iain

Raspberry Pi USB2 audio fixed (apparently)
by Julian Brooks 02 Jul '13

02 Jul '13

Hey all, So, umm, yeah. Is everyone on this already? Just got a message saying that an 'rpi-update' should fix the usb2 problems for soundcards. Not checked 'cos I spent bloody ages tracking down soundcards that did work. Good to know though. http://www.raspberrypi.org/phpBB3/viewtopic.php?p=364163&sid=04807df00bff9f… http://www.raspberrypi.org/phpBB3/viewtopic.php?p=362690#p362690 http://www.raspyfi.com/raspberry-pi-usb-audio-fix/ (anyone checked out this distro btw?) Good to hear there seems to be lots of audio tweaks and exploration going on on the Pi (still:) Best wishes, Julian

[PD-announce] Deadline EXTENDED to July 9 -- Musical Metacreation Workshop (MUME2013)
by Graeme McCaig 29 Jun '13

29 Jun '13

Call for Participation -- please distribute widely ============================= Musical Metacreation 2013 DEADLINE EXTENSION Submissions Now Due July 9 ============================= ((( MUME 2013 ))) 2nd International Workshop on Musical Metacreation http://www.metacreation.net/mume2013/ Held at the Ninth Annual AAAI Conference on Artificial Intelligence and Interactive Digital Entertainment (AIIDE'13) Northeastern University, Boston, Massachusetts, USA October 14-15, 2013 ---------------------- News: New Deadline for Paper and Demo Submissions: *** July 9, 2013 *** New Info for Interested Industry Presenters: http://www.metacreation.net/mume2013/industry ====================== We are delighted to announce the 2nd International Workshop on Musical Metacreation (MUME2013) to be held October 14 and 15, 2013, in conjunction with the Ninth Annual AAAI Conference on Artificial Intelligence and Interactive Digital Entertainment (AIIDE'13). MUME2013 builds on the enthusiastic response and participation we received for the inaugural workshop in 2012, which received 31 submissions, 17 of which were accepted (a 55% acceptance rate). This year the workshop has expanded to 2 days. Thanks to continued progress in artistic and scientific research, a new possibility has emerged in our musical relationship with technology: Generative Music or Musical Metacreation, the design and use of computer music systems which are "creative on their own". Metacreation involves using tools and techniques from artificial intelligence, artificial life, and machine learning, themselves often inspired by cognitive and life sciences. Musical Metacreation suggests exciting new opportunities to enter creative music making: discovery and exploration of novel musical styles and content, collaboration between human performers and creative software "partners", and design of systems in gaming and entertainment that dynamically generate or modify music. MUME brings together artists, practitioners and researchers interested in developing systems that autonomously (or interactively) recognize, learn, represent, compose, complete, accompany, or interpret music. As such, we welcome contributions to the theory or practice of generative music systems and their applications in new media, digital art, and entertainment at large. Join us at MUME2013 and take part in this exciting, growing community! Topics ====== We encourage paper and demo submissions on topics including the following: * Novel representations of musical information * Systems for autonomous or interactive music composition * Systems for automatic generation of expressive musical interpretation * Systems for learning or modelling music style and structure * Systems for intelligently remixing or recombining musical material * Advances or applications of AI, machine learning, and statistical techniques for musical purposes * Advances or applications of evolutionary computing or agent and multiagent-based systems for musical purposes * Computational models of human musical creativity * Techniques and systems for supporting human musical creativity * Online musical systems (i.e. systems with a real-time element) * Adaptive and generative music in video games * Methodologies for, and studies reporting on, evaluation of musical metacreations * Emerging musical styles and approaches to music production and performance involving the use of AI systems * Applications of musical metacreation for digital entertainment: sound design, soundtracks, interactive art, etc. Format and Submissions ====================== The workshop will be a two day event including: * Presentations of FULL TECHNICAL PAPERS (8 pages maximum) * Presentations of POSITION PAPERS and TECHNICAL IN-PROGRESS WORK (5 pages maximum) * Presentations of DEMONSTRATIONS (3 pages maximum) * One or more PANEL SESSIONS (potential topics include international and networked collaborations, evaluation methodologies, generative music in art vs. games) * Presentations by INDUSTRY PARTNERS Workshop papers will be published in a Technical Report by AAAI Press and will be archived in the AAAI digital library. Submissions should be made in AAAI, 2-column format; see instructions here: http://www.aaai.org/Publications/Author/author.php We also invite companies involved in Musical Metacreation and its application to present their work and challenges to the MUME community. Each industrial partner selected will be given a timeslot to present/demo during the workshop. Interested industry representatives, for more info see: http://www.metacreation.net/mume2013/industry For complete details on attendance, submissions and formatting, please visit the workshop website: *** http://www.metacreation.net/mume2013/ *** Important Dates =============== Submission deadline: July 9, 2013 Notification date: August 6, 2013 Accepted author CRC due to AAAI Press: August 14, 2013 Workshop date: October 14-15, 2013 Workshop Organizers =================== Dr. Philippe Pasquier (Workshop Chair) School of Interactive Arts and Technology (SIAT) Simon Fraser University, Vancouver, Canada Dr. Arne Eigenfeldt School for the Contemporary Arts Simon Fraser University, Vancouver, Canada Dr. Oliver Bown Design Lab, Faculty of Architecture, Design and Planning The University of Sydney, Australia Graeme McCaig (Administration & Publicity Assistant) School of Interactive Arts and Technology (SIAT) Simon Fraser University, Vancouver, Canada Program Committee ================= Gérard Assayag - IRCAM-France Al Biles - Rochester Institute of Technology - USA Tim Blackwell - Department of Computing, Goldsmiths College, University of London - UK Alan Blackwell - Cambridge University - UK Oliver Bown - The University of Sydney - Australia Andrew Brown - Queensland Conservatorium, Griffith University - Australia Jamie Bullock - Integra Lab, Birmingham Conservatoire - UK Karen Collins - University of Waterloo - Canada Nick Collins - University of Sussex - UK Darrell Conklin - University of the Basque Country - Spain Arne Eigenfeldt - Simon Fraser University - Canada Jason Freeman - Georgia Institute of Technology - USA Guy Garnett - University of Illinois - USA Toby Gifford - Griffith University - Australia Luke Harrald - Elder Conservatorium of Music, The University of Adelaide - Australia Bill Hsu - Department of Computer Science, San Francisco State University - USA Robert Keller - Harvey Mudd College - USA Nyssim Lefford - Audio Technology, Luleå University of Technology - Sweden George Lewis - Department of Music, Columbia University - USA Aengus Martin - Faculty of Engineering, The University of Sydney - Australia James Maxwell - Simon Fraser University - Canada Graeme McCaig - School of Interactive Arts and Technology, Simon Fraser University - Canada Jon McCormack - Centre for Electronic Media Art, Monash University - Australia James McDermott - Complex and Adaptive Systems Laboratory, University College Dublin - Ireland Alex McLean - ICSRiM - University of Leeds - UK Kia Ng - ICSRiM - University of Leeds - UK Philippe Pasquier - School of Interactive Arts and Technology, Simon Fraser University - Canada Marcus Pearce - Queen Mary, University of London - UK Robert Rowe - New York University - USA Benjamin Smith - Case Western Reserve University - USA Richard Stevens - Leeds Metropolitan University - UK Michael Sweet - Berklee College of Music - USA Peter Todd - Indiana University - USA Dan Ventura - Brigham Young University - USA Ivan Zavada - Conservatorium of Music, The University of Sydney - Australia ---------------------- http://www.metacreation.net/mume2013/ ====================== _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

... that's why you let automake generate them. :D autools is great *after* you spend tons of time getting it setup *just* right. Until then, it's hell.

How to make a looper ?
by Pierre Massat 27 Jun '13

27 Jun '13

Dear list, i've been working on a simple looper (the sound on sound thing, Eno & Fripp, Eno all by himself, you know what I mean). I decided to use two tables, write to T1 while reading T2, and write to T2 while reading T1, adding the input and the currently playing table together before writing. I'm faced with two issues. One is a click I hear everytime I record a new piece of sound (I m almost certain it happens while switching from one table to the other), and another is final volume. What is the proper way of reading two tables continuously and alternatively ? And conversely, what is the proper way of writing continuously to two tables alternatively ? I'm currently using threshold~. About the final volume, the problem is that the first sound i record gets burried in the later recordings, and it all ends up distorting because it too loud in the end. I suppose I should use a limiter on the input, and maybe compress the output. Is that correct ? Can someone point me to a good compressor/limiter in Pd ? Or maybe there's a much better way to make a looper in Pd... Cheers, Pierre.

Did you install Xcode? You need more than the commandline tools, that's just git and a bunch of other things like it. The compiler and frameworks come with the Xcode app itself. You didn't find any info on Google because it's Mac and *everyone* installs the GUI app first (aka Xcode), so they'd already have it. nstall that, then go to the Downloads tab in the preferences, and make sure the Commandline Tools is installed there. If not, install it. Then configure & make will work. I was actually working with portaudio for another project and it compiles fine for me. For reference: SDKs are installed to: /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs You can also see in Xcode in the project build settings: click on project in project tree, select Build Settings tab, there should be an entry for the SDK with a dropdown box On Jun 26, 2013, at 5:59 PM, pd-list-request(a)iem.at wrote: > From: Jonathan Wilkes <jancsika(a)yahoo.com> > Subject: [PD] compiling pd vanilla on a mac > Date: June 26, 2013 5:47:58 PM EDT > To: pd-list <pd-list(a)iem.at> > Reply-To: Jonathan Wilkes <jancsika(a)yahoo.com> > > > Hi, > Any clues about this ./configure error: > configure: error: Couldn't find 10.5, 10.6, or 10.7 SDK > configure: error: ./configure failed for portaudio > > I have no clue how to check what SDK version I have installed (Google returns nothing useful) > > For reference: > After agreeing to some stupid license agreement that I didn't read I downloaded the > stupid "Command Line Tools (OSX Lion) for Xcode - 2013" which claims > to include the the "Mac OSX SDK Frameworks and headers" (which I had to type > out because their stupid webpage doesn't allow you to copy/paste the stupid text). > > Thanks, > Jonathan -------- Dan Wilcox @danomatika danomatika.com robotcowboy.com
