is pdp supposed to work?
by Matteo Sisti Sette 01 Feb '11

01 Feb '11

Hi, I just downloaded Pd-Extended 0.42.5 for Ubuntu (i was using an older snapshot which had some troubles) and tried to open some pdp examples, but they don't work, at least not out-of-the-box. They don't open any window and there is no "create" message or anything that looks like it is supposed to open a window - so I guess it is supposed to open automatically, isn't it? Anyway if I send a [create( message to pdp_glx a window is opened but nothing happens in it. When I bang the metro in the examples, I start getting the following errors: pdp_v4l: auto open failed pdp_v4l: no device opened pdp_v4l: attempting auto open pdp_v4l: retry count reached zero for /dev/video0 pdp_v4l: try to open manually Any idea of what can be the problem? Am I missing something? thanks m.

[PD-announce] 3rd International Symposium on Ambisonics and Spherical Acoustics
by Erika Olsen 31 Jan '11

31 Jan '11

3rd International Symposium on Ambisonics and Spherical Acoustics June 2-3, 2011 Lexington, Kentucky, USA www.vis.uky.edu/ambisonics2011<http://www.vis.uky.edu/ambisonics2011> Dear Colleagues, We would like to announce the 3rd International Symposium on Ambisonics and Spherical Acoustics, which will be organized by the Center for Visualization and Virtual Environments at the University of Kentucky. The Symposium will be held to provide an intensive exchange between industrial and academic researchers working in various research areas on spherical acoustics. The field of spatial sound reproduction is interdisciplinary by nature and closely related to a number of computer science and engineering areas such as acoustics, mathematics, signal processing, and perception. The symposium focuses on discussing the various problems and solutions concerning the capture, analysis, and re-synthesis of sound fields applying spherical acoustics; for example higher-order Ambisonics (HOA), and spherical microphone arrays. The symposium is going to be divided into oral presentations (keynotes and submissions), poster sessions, and will also feature demos and artistic performances. This symposium will benefit from a hemi-spherical loudspeaker array that will be installed in the Digital Amphitheater of the newly inaugurated Davis Marksbury Building. Original contributions are encouraged in, but not limited to, the following topics: * General considerations on spherical acoustics theory * Ambisonic for sound scene reproduction and virtual acoustic environments * Spherical microphone array systems and signal processing * Capture and analysis of radiation patterns * Spherical acoustic holography * Synthesis of directional and focused sound sources * Spherical loudspeaker array systems and signal processing * Theoretical considerations on comparative subjective and objective studies * Standardization, exchange, implementation and hardware issues Submission ========== Submissions will be judged based on extended abstracts (1000 words). Procedures to submit papers, posters, and demo sessions are detailed at the symposium website http://www.vis.uky.edu/ambisonics2011/. Final papers must be camera-ready conforming to the format specified on the submission website. Important dates =============== * Extended abstract (1000 words) submission due: February 15th, 2011 * Papers, Notification of acceptance: February 21, 2011 * Camera-ready copy (full paper): April 30, 2011 * Registration opens: April 30, 2011 * Submission of Audio Material for Testing: May 13, 2011 * Symposium Dates: June 2-3, 2011 If you have any questions, please contact office(a)ambisonics-symposium.org<mailto:office@ambisonics-symposium.org> Symposium Chairs ================ General Co-Chairs Jens Hannemann (VisCenter) Kevin Donohue (VisCenter) Administrative Chair Erika Olsen (VisCenter) _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

trouble with library paths
by Matteo Sisti Sette 31 Jan '11

31 Jan '11

Hi, I think there are some libraries that are not being added to the classpath by default in Pd-Extended, and I wonder whether there is a particular reason for that or if it is just a "bug" in the distribution. Among other things, I would expect help patches to work out of the box, and I wouldn't expect a library to be included in Pd-Extended if it depends on another one which is not. That said, the issues that I detected so far are: - the [pix_blobtracker] abstraction doesn't create unless you write it [Gem/pix_blobtracker] However, if you open its help patch from the help broser, the object [pix_blobtracker] contained in it does create. Since the Gem library is loaded by default and all Gem objects are available without writing the [Gem/... ] prefix, I guess it would be cleaner to have Gem added to the path by default so that the abstractions are available as well. Or is there some reason against that? - the [pix_blobtracker] abstraction contains some objects from iemmatrix which are actually included in pd Extended, but the library's path is not added by default. Inside pix_blobtracker, they are written without the path, so the way Pd-Extended is distributed (i.e. out of the box) they don't create and [pix_blobtracker] doesn't work. You need either to replace [mtx_,...] with [iemmatrix/mtx_...] within [pix_blobtracker] or to add iemmatrix to the path. It seems indeed that none of the iem_... libraries is included by default in the path. Is there a reason why they are not while most other libraries in pd_extended are? thanks m.

Re: [PD] dissonance_curves_mod.pd

> So here it is Where? I get the digests, so I missed it? Anyway, I work with dissonance curves and presented a paper about it at PdCon07. I've also been making objetcs out of the patches now (with the help of Mathieu). I know of other peple that work with that in Pd, but I haven't seen the patch. cheers Alex Date: Sat, 22 Jan 2011 10:12:31 -0800 (PST) From: richard duckworth <richduckworth(a)yahoo.com> Subject: Re: [PD] dissonance_curves_mod.pd To: pd-list(a)iem.at Message-ID: <809386.88729.qm(a)web39404.mail.mud.yahoo.com> Content-Type: text/plain; charset="iso-8859-1" I have been chided off list for not attaching the file.?

3dp?
by Matteo Sisti Sette 31 Jan '11

31 Jan '11

Hi, I'm not sure what 3dp is, but I noticed a 3dp folder in the help browser and tried to open some examples. However all the [3dp_...] objects couldn't create. I have Pd-Extended 0.42.5 (just downloaded) on Ubuntu 10.04 Any idea? thanks m.

sound card preferences
by Marco Donnarumma 31 Jan '11

31 Jan '11

You could use the -audiodev flag ( http://en.flossmanuals.net/PureData/AdvancedConfig) but I never used it on Mac, so I'm not sure whether it is appliable; with flags you could also specify sound servers/API to playback with. So another solution could just be to use jack (I usually reccommend to install jack on Mac for better flexibility and efficiency). Then you would start jack with an appropriate profile and Pd with -jack and -channels flag and you're done. http://freefr.dl.sourceforge.net/project/jackosx/JackOSX/0.87/JackOSX.0.87.… best, Marco > i need to tell a patch to select an external sound card when it loads. > what's the most efficient method? flags? im on osx, pd-extended, card > is a focusrite saffire pro 24. > cheers > -- Marco Donnarumma aka TheSAD Independent New Media Arts Professional, Performer, Teacher Ongoing MSc by Research, University of Edinburgh, UK PORTFOLIO: http://marcodonnarumma.com LAB: http://www.thesaddj.com | http://cntrl.sourceforge.net | http://www.flxer.net EVENT: http://www.liveperformersmeeting.net
