Binaural processing
by Stefan Turner 15 Mar '04

15 Mar '04

Hey everyone. This is my first post and I'm still not too experienced with PD, so go easy! I have to do a large software project at university next year, and I thought this might be a good excuse to code something for PD. I want to make an object which takes a multichannel sound, together with binaural data such as HRTFs, 'room' attributes, physical location of sound signals within the 'room', etc, and outputs a binaural signal. My question is whether it has already been done before, because if it has I would rather use the existing object and try something else. I have heard of spat~, which seems to be Max-only and not free, and rvbap, which doesn't do binaural processing. Thanks for any help. Cheers, Stefan ___________________________________________________________ Yahoo! Messenger - Communicate instantly..."Ping" your friends today!

PD Knoppix
by derek holzer 14 Mar '04

14 Mar '04

Last week I accidentally Googled up a Knoppix-based live CD intended for Pure Data usage! Recalling the discussion we had a while back about "executables" and so on, I thought it would be interesting to post it here. Apologies if the original creator of this disk has already brought it to your attention: http://stream.sil.at/pdknoppix/ This disk boots fine on my PC laptop, but I find a few things missing: Jack, PDP and PiDiP to name a few. Maybe if "eof" would like to get in touch, the mission could be continued? Did I mention that, at 202 Mb, you can fit it on a mini-CD? How horribly cute! ;-) best, D. -- derek holzer ::: http://www.umatic.nl ---Oblique Strategy # 168: "Use fewer notes"

Re: [PD] Still with the GEM!

I am at a loss. Ive tried upgrading my gcc and elf (whatever that is) but that had no effect. I installed xfree86 libMesaGL and libMesaGlu, with no effect. The compiler is obviously having no trouble finding the GL library, it just has trouble using it. Ive searched the net and found compile errors like this one, but I havent found the solution. Can anyone help me? Once I get Gem built, I wont have to build any more stuff for a while. Im so close! Pleas help! Heres my config command: ./configure --with-glut --with-gltt --with-ftgl --with-mpeg3 --with-quicktime --with-avi --with-ieee1394 --enable-mmx And heres my config.log int main() { sin() ; return 0; } configure:2525: checking for main in -lz configure:2540: gcc -o conftest -g -O2 -L/usr/X11R6/lib conftest.c -lz -Wl,-shared -Wl,-export-dynamic -lXxf86vm -lXext -lX11 1>&5 /usr/lib/libc_nonshared.a(elf-init.oS)(.text+0x1c): In function `__libc_csu_init\': : undefined reference to `__init_array_end\' /usr/lib/libc_nonshared.a(elf-init.oS)(.text+0x22): In function `__libc_csu_init\': : undefined reference to `__init_array_start\' /usr/lib/libc_nonshared.a(elf-init.oS)(.text+0x37): In function `__libc_csu_init\': : undefined reference to `__init_array_start\' /usr/lib/libc_nonshared.a(elf-init.oS)(.text+0x5b): In function `__libc_csu_fini\': : undefined reference to `__fini_array_end\' /usr/lib/libc_nonshared.a(elf-init.oS)(.text+0x61): In function `__libc_csu_fini\': : undefined reference to `__fini_array_start\' /usr/lib/libc_nonshared.a(elf-init.oS)(.text+0x7f): In function `__libc_csu_fini\': : undefined reference to `__fini_array_start\' /usr/bin/ld: conftest: hidden symbol `__fini_array_end\' isn\'t defined collect2: ld returned 1 exit status configure: failed program was: #line 2533 \"configure\" #include \"confdefs.h\" int main() { main() ; return 0; } configure:2670: checking for glInitNames in -lGL configure:2689: gcc -o conftest -g -O2 -L/usr/X11R6/lib conftest.c -lGL -Wl,-shared -Wl,-export-dynamic -lXxf86vm -lXext -lX11 1>&5 /usr/lib/libc_nonshared.a(elf-init.oS)(.text+0x1c): In function `__libc_csu_init\': : undefined reference to `__init_array_end\' /usr/lib/libc_nonshared.a(elf-init.oS)(.text+0x22): In function `__libc_csu_init\': : undefined reference to `__init_array_start\' /usr/lib/libc_nonshared.a(elf-init.oS)(.text+0x37): In function `__libc_csu_init\': : undefined reference to `__init_array_start\' /usr/lib/libc_nonshared.a(elf-init.oS)(.text+0x5b): In function `__libc_csu_fini\': : undefined reference to `__fini_array_end\' /usr/lib/libc_nonshared.a(elf-init.oS)(.text+0x61): In function `__libc_csu_fini\': : undefined reference to `__fini_array_start\' /usr/lib/libc_nonshared.a(elf-init.oS)(.text+0x7f): In function `__libc_csu_fini\': : undefined reference to `__fini_array_start\' /usr/bin/ld: conftest: hidden symbol `__fini_array_end\' isn\'t defined collect2: ld returned 1 exit status configure: failed program was: #line 2678 \"configure\" #include \"confdefs.h\" /* Override any gcc2 internal prototype to avoid an error. */ /* We use char because int might match the return type of a gcc2 builtin and then its argument prototype would still apply. */ char glInitNames(); int main() { glInitNames() ; return 0; } configure:2715: checking for glInitNames in -lMesaGL configure:2734: gcc -o conftest -g -O2 -L/usr/X11R6/lib conftest.c -lMesaGL -Wl,-shared -Wl,-export-dynamic -lXxf86vm -lXext -lX11 1>&5 /usr/bin/ld: cannot find -lMesaGL collect2: ld returned 1 exit status configure: failed program was: #line 2723 \"configure\" #include \"confdefs.h\" /* Override any gcc2 internal prototype to avoid an error. */ /* We use char because int might match the return type of a gcc2 builtin and then its argument prototype would still apply. */ char glInitNames(); int main() { glInitNames() ; return 0; }

Hello, I installed plugin~ under linux and when I try to used it I have this error message and there's no gui anymore in pd? bad screen distance "117,000000" When I tried to used an example of plugin~ I have kind of same message : Unable to find label "lpf" in plugin library file "delay.so". error: plugin~: Unable to find LADSPA plugin "lpf" within library "delay.so" error: plugin~: Unable to open LADSPA plugin plugin~ lpf delay.so ... couldn't create plugins~.pd 4 0 10 1 (adc~->text) connection failed plugins~.pd 4 1 10 1 (adc~->text) connection failed plugins~.pd 6 0 10 0 (message->text) connection failed plugins~.pd 7 0 10 0 (message->text) connection failed plugins~.pd 8 0 10 0 (message->text) connection failed bad screen distance "230,000000" so I checked my tcl/tk version which is ok, I check my laspa_path and no way... If you someone have got an idea on what to do, thanks a lot best juto

Live motion tracking using pd / gem / GridFlow / PiDiP
by Max Neupert 14 Mar '04

14 Mar '04

Hi list, I am working on a project where I want to confront the observer with a projection that changes according to his/her position, thus eliminating the effects of perspective. http://www.revolwear.com/p The part with the distortion of the image is already done, so what is left is the live video tracking (positioning) of the spectator. I want to extract from a video feed (firewire NTSC cam) the position in coordinates X,Y. This is promised to be done by the gem object pix_movement like suggested in http://iem.kug.ac.at/mailinglists/pd-list/2003-10/006848.html So I tried that, the problem is that the object just understands the RGB colorspace, converting the YUV camera stream first seems quite a processing task for the computer. I succeded in creating a gem patch according to the tutorial patch which does something, but there is no working tracking (see attached patch) Installing PDP & PiDiP did not lead to a big success either because of a knowledge-lack on my side as well as few documentation and poor performance on OSX. http://iem.kug.ac.at/mailinglists/pd-list/2003-10/006710.html The links in this suggestion are broken. Has anybody experiences with motion tracking in pure data using whatever extension? I would like to put a helpful page online with my experience as soon as I get it working. Also I'll be on Saturday at the user group meeting at the SAT. -- Max Neupert Montréal http://www.sat.qc.ca/calendrier/2004/03-04/30_0304.html#english

Re: [PD] Still with the GEM!

Hello all, For the latest installment of configure errors apparently only I am having with cvs Gem, and Fedore Core 2 (1.9), and linux 2.6.3 If indeed the error is in usr/lib/libc_nonshared.a, then here are some possabilities for why. I dont know enough about compiling on linux to recognize the culprit... One possability: http://list-archive.xemacs.org/xemacs-beta/200403/msg00014.html Im going to try to update my glibc to see if that fixes the problem. On the up-note, I got my hammerfall multiface working with linux 2.6.3. It turned out to be a broblem on my part. Once I learned that there was a special firmware loader AND a special mixer for this card it all became easy. I have to use jack for pd and oss emulation for xmms as direct alsa usage seems prohibited by error. Thanks to all thoes who helped! Like Frank Barknecht for example! Thanks all, -thewade

Live motion tracking using pd / gem / GridFlow / PiDiP
by Trevor Agus 13 Mar '04

For motion-tracking, http://www.eyesweb.org/ is pretty powerful. It can be linked to PD via internal MIDI or perhaps other means. Trevor
