[PD-announce] Deadline extension: Int. Symposium on Ambisonics and Spherical Acoustics 2010 - Submission of Abstracts due January 15th!
by Markus Noisternig 08 Jan '10

08 Jan '10

[Apologies if you receive multiple copies of this message.] *** The paper / demo submission deadline has been extended to January 15th, 2010. *** ----------------------------------------------------------- 2nd Int. Symposium on Ambisonics and Spherical Acoustics Dates: 2010 May 6-7, Paris, France ambi10 - Call for Participation http://ambisonics10.ircam.fr Dear Colleagues, We would like to announce the 2nd International Symposium on Ambisonics and Spherical Acoustics, which will be organized by IRCAM, together with LIMSI-CNRS and France Telecom/Orange Labs. 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 two demonstration sessions (artistic and technical). This symposium will benefit from a hemi- spherical loudspeaker array that will be installed for the duration of the symposium, which will be held in the Espace de projection, the variable acoustics performance hall of Ircam. 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://ambisonics10.ircam.fr. Final papers must be camera-ready conforming to the format specified on the submission website. Several excellent papers will be selected for collective submission to Acta Acustica united with Acustica. These papers will be expanded versions of the presented works, and will go through the standard peer review process. The official language of the symposium is English. Important dates =============== *** Extended abstract (1000 words) submission due: January 15th, 2010 (extended deadline) *** * Papers, Notification of acceptance due: February 19th, 2010 * Camera-ready copy (full paper): March 12, 2010 * Registration opens: March 22, 2010 * Late Registration: April 12, 2010 * Submission of Audio Material for Testing: April 19, 2010 * Symposium Dates: May 6-7, 2010 If you have any questions, please contact ambisonics10(a)ircam.fr Symposium Chairs ================ General Co-Chairs Markus Noisternig (IRCAM - UMR CNRS) Brian FG Katz (LIMSI - CNRS) Rozenn Nicol (France Telecom - Orange Labs) Technical Program Co-Chairs Nicolas Misdariis (IRCAM - UMR CNRS) Olivier Warusfel (IRCAM) Administration Chair Sylvie Benoit (IRCAM) _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

Which pd-extended on Jaunty (64)?
by András Murányi 07 Jan '10

07 Jan '10

Hi All, After my Odyssey (with your support) to compile extended on amd64 I still had some basic problems with it, namely: - Didn't like each other with the gui-rewrite - The GUI was very slow! ...so I decided to try an i386 autobuild, but Pd-0.42.5-extended-ubuntu-jaunty-i386.deb<http://autobuild.puredata.info/auto-build/latest/Pd-0.42.5-extended-ubuntu-…>throws this error: Application initialization failed: Can't find a usable init.tcl in the > following directories: > /usr/lib/pd/tcl/library /usr/share/tcltk/tcl8.5 ./lib/tcl8.5 > ./lib/tcl8.5 ./library ./library ./tcl8.5.0/library ./tcl8.5.0/library > > /usr/share/tcltk/tcl8.5/init.tcl: version conflict for package "Tcl": have > 8.5.0, need exactly 8.5.6 > version conflict for package "Tcl": have 8.5.0, need exactly 8.5.6 > while executing > "package require -exact Tcl 8.5.6" > (file "/usr/share/tcltk/tcl8.5/init.tcl" line 20) > invoked from within > "source /usr/share/tcltk/tcl8.5/init.tcl" > ("uplevel" body line 1) > invoked from within > "uplevel #0 [list source $tclfile]" > > This probably means that Tcl wasn't installed properly. > Now my Tcl is 8.5.6, had even reinstalled it. To tell you the truth, I'm not so much into compiling or doing tricks now*, I just want to get my hands on a well working copy and make music. Can you give me some advice? Jaunty, amd64. Thanks, Andras *because I got the cold :o/

Hello, this would work on linux: http://www.cyberciti.biz/faq/linux-increase-the-maximum-number-of-open-file… does this work on OSX?: in /System/Library/StartupItems/SystemTuning/SystemTuning modify following values: sysctl -w kern.sysv.shmmax sysctl -w kern.sysv.shmmin sysctl -w kern.sysv.shmmni sysctl -w kern.sysv.shmseg sysctl -w kern.sysv.shmall ? open twenty instances of readsf~ and trig it several times to reproduce the bug Patko Damian Stewart a écrit: hey, on OSX, if i accidentally trigger an infinite loop situation with a readsf~, it eats up all Pd's filehandles; then when i try to save another patch, i get error: filename.pd: Too many open files it seems to me as if readsf~ isn't freeing the filehandle if its call to fopen fails. -- damian stewart

[pddp/pddplink] Error
by Alexandre Porres 07 Jan '10

07 Jan '10

Hi there, I am using the [pddp/pddplink] objetcs and I keep getting anoying error messages everytime I open the patch. I use Mac OS 10.6 I am using it in a way such as: [pddp/pddplink http://puredata.info] and I get: ============ Application Error Error: wrong # args: should be "pdd... ============== then the options: OK, Skip Messages, Details =============== Details gives me: wrong # args: should be "::pddp::srvUse ?root? ?port?" wrong # args: should be "::pddp::srvUse ?root? ?port?" while executing "::pddp::srvUse /Users/alexandreporres/Desktop/!BOOK/Tutorial de Puredata - Por Alexandre Porres (2010-5-jan)" ("after" script) ================================= The links work alright anyway, so I don;t know why the complaints... Anyone might be aware of what I'm doing wrong or need to do? Thanks Alex

PD with SnowLeopard
by Morgan Evans-Weiler 06 Jan '10

06 Jan '10

Is anybody having problems running Pd extended with Snow Leopard? I'm having trouble getting it running correctly without it freezing up. It will work fine for a few minutes but soon freezes and will not let me open or close files or open or close the program. I would appreciate any help. Thanks Morgan

Matteo Sisti Sette escribiÃ³: > > Is this really all [separator] does? Stupid question: Obviously it isn't (just had a look at the source code though I don't understand a line). But for what my patch does, it seems that replacing separators with a push and pop has no side effects, fortunately. -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com

pix_mulitblob and matrix
by olsen 05 Jan '10

05 Jan '10

hi thanks to IOhannes indications i'm feeding my pix_mulitblob output into the iemmatrix now. as long as there're enough blobs in the picture it works pretty nice. but as soon as there're less blobs than given in the argument to pix_multiblob i get: error: $43: argument number out of range error: $44: argument number out of range ... for all the arguments of undetected blobs. and as soon as there's no blob in the picture the pd-shell reports: matrix : corrupt matrix passed do i do something wrong? i was using the attached patch thanks for help & hints olsen -- ETs DNA will not be televised

(rectangular textures) Can't see what's wrong here
by Matteo Sisti Sette 05 Jan '10

05 Jan '10

Hi, I must be stupid or something. I can't see any relevant difference between the attached patch (and its shader) and the example "01 simple texture" in the "10 GLSL" folder. However, the abovementioned example works fine here, while the attached example shows up as a all-one-color square (probably the color of one corner pixel of the image). It looks much like an attempt to use normalized coordinates (0..1) where whatevertheyarecalled coordinates are expected (0..width,0..height). However, "my" shader seems identical to Cyrille's one and I'm sending the [rectangle 1( message to all textures, so I can't understand why one works while the other doesn't... It must be right in front of my eyes but I don't see it. (oh you need img1,2,3.jpg from the example folder to test it) thanks m. -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com #N canvas 393 27 1264 656 12; #X obj 441 576 gemwin; #X msg 437 515 create \, 1; #X msg 484 547 destroy; #X obj 58 177 glsl_vertex; #X obj 59 313 glsl_fragment; #X obj 143 211 change; #X obj 160 342 change; #X obj 155 385 t b f; #X obj 153 418 pack 0 0; #X obj 60 490 glsl_program; #X msg 154 454 link \$1 \$2; #X obj 59 543 pix_texture; #X obj 188 24 bng 15 250 50 0 empty empty empty 17 7 0 10 -262144 -1 -1; #X obj 353 162 pix_image img1.jpg; #X obj 506 163 pix_image img2.jpg; #X obj 69 33 gemhead 50; #X obj 353 73 gemhead 22; #X obj 508 77 gemhead 23; #X obj 348 263 pix_texture; #X obj 511 259 pix_texture; #X msg 373 221 texunit 0; #X msg 519 221 texunit 1; #X msg 229 387 curtex 0; #X obj 664 260 pix_texture; #X obj 661 78 gemhead 24; #X msg 672 222 texunit 2; #X obj 659 164 pix_image img3.jpg; #X floatatom 212 525 5 0 0 0 - - -; #X obj 70 60 t a a; #X obj 56 122 separator; #X msg 349 409 rectangle 1; #X obj 348 384 loadbang; #X msg 757 119 rectangle 1; #X obj 762 53 loadbang; #X msg 136 99 open trivialshader.vert; #X msg 114 259 open trivialshader.frag; #X obj 60 600 square 4; #X connect 1 0 0 0; #X connect 2 0 0 0; #X connect 3 0 4 0; #X connect 3 1 5 0; #X connect 4 0 9 0; #X connect 4 1 6 0; #X connect 5 0 8 0; #X connect 6 0 7 0; #X connect 7 0 8 0; #X connect 7 1 8 1; #X connect 8 0 10 0; #X connect 9 0 11 0; #X connect 9 1 27 0; #X connect 10 0 9 0; #X connect 11 0 36 0; #X connect 12 0 34 0; #X connect 12 0 35 0; #X connect 13 0 18 0; #X connect 14 0 19 0; #X connect 15 0 28 0; #X connect 16 0 13 0; #X connect 17 0 14 0; #X connect 20 0 18 0; #X connect 21 0 19 0; #X connect 22 0 9 0; #X connect 24 0 26 0; #X connect 25 0 23 0; #X connect 26 0 23 0; #X connect 28 0 29 0; #X connect 29 0 3 0; #X connect 30 0 11 0; #X connect 31 0 30 0; #X connect 32 0 23 0; #X connect 32 0 19 0; #X connect 32 0 18 0; #X connect 33 0 32 0; #X connect 33 0 25 0; #X connect 33 0 21 0; #X connect 33 0 20 0; #X connect 34 0 3 0; #X connect 35 0 4 0; // Cyrille Henry 2007 void main() { gl_TexCoord[0] = gl_MultiTexCoord0; gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex; } // porcodio #extension GL_ARB_texture_rectangle : enable uniform sampler2DRect curtex; void main (void) { vec2 xy=gl_TexCoord[0].st; vec4 frontcolor = texture2DRect(curtex, xy); gl_FragColor = frontcolor; }

Re: [PD] pdp_qt problems
by Ed Kelly 05 Jan '10

05 Jan '10

Duh! I was missing the meaning of the error. It was a problem with my software, not pdp_qt It's the usual problem with the [route routeme] object when sending it a list prefixed as [list routeme data( It's been a while since I looked at PD, and this problem has pooped before - but simply putting a [route list] before the [route myroute] solves it. Funny how it didn't happen before! Ah well... ...the fixed version works.
