Re: [PD] wmv playback in puredata / gem
by chris clepper 26 Jul '06

26 Jul '06

>hi, >has anyone played .wmv files in puredata / gem ? or other graphic addons for >puredata? Depends on the OS. The flip4mac component for Quicktime on OSX should work. They won't play on the Windows version at all. Linux might be able to play some of them with ffmpeg. WMV (and the MPEGs) is not really useful beyond datarate limited end consumer delivery. GEM does not fall into that category.

compiling fluid~ on osx

Hello all, Trying to compile fluid~ on osx lately, with flext from cvs, I get: <snip> g++ -bundle -bundle_loader /Users/dc/dev/puredata/millerPD/bin/pd - dynamic -framework ApplicationServices -framework vecLib -Wl,-S -L/ Users/dc/dev/puredata/millerPD/bin -L/usr/local/lib -o pd-darwin/ release-single/fluid~.pd_darwin pd-darwin/release-single/main.opp - lfluidsynth -lflext-pd_s /usr/bin/ld: Undefined symbols: flext_dsp_single::Exit() flext_dsp_single::CbDsp() flext_dsp_single::Setup(flext_class*) </snip> I'm using the normal 'bash ../../grill/flext/build.sh pd gcc' from the footils directory. If I try directly with: g++ -bundle -bundle_loader /Users/dc/dev/puredata/millerPD/bin/pd - flat_namespace pd-darwin/fluid.o -lm -L/usr/local/lib /Users/dc/dev/ puredata/externals/grill/flext/pd-darwin/release-single/libflext-pd_s. 0.5.1.a -framework veclib -o pd-darwin/fluid.pd_darwin I get the same error. Can anyone help? The libraries are in /usr/local/lib, I've checked. d

Syncgrain~ object
by ailbhe＠voltdeplume.com 26 Jul '06

26 Jul '06

Hi there, Got no reply to this the last time so I am putting it out there again! I have a usb drumkit sending signals to pd using a pico device. I have a different note assigned to all six drum pads. I would like to use the syncgrain object to disperse these notes into sonic particles when the drum pad is touch. It is working okay at the minute with two pads up and running and two seperate syncgrain objects. I am just wonder though if I should use one and attach six different parameter settings to it instead. If someone could respond that would be great or else I will come to Vienna and hunt ye down! kidding A

[announce] Open Call Locus Sonus Audio Streaming
by jerome joy 26 Jul '06

26 Jul '06

(reminder) Hi PD-list readers, ______________________________________ OPEN CALL | LOCUS SONUS http://locusonus.org/ August 2006 Open Call to participate in the Locus Sonus Audio Streaming project !! * This is a call from the French based Audio in art research group Locus Sonus to participate in their streamed soundscapes open web-mike project. * Open an ogg audio stream from your home or garden (no pre-recorded playlists please) and become a remote member of the Locus Sonus orchestra. * Locus Sonus proposes to use the sound from your environment as raw material for their installations and performances. As an added bonus all streams will be made available on a web page so that you can do your own international mix at will. * We are hopeing to obtain a variety of streams from diverse and exotic locations, the imaginative potential of the project and it's future development depends on diversity and richness the streams you propose. We will be happy to discuss artistic and technical issues with you. * To participate in this project, contact support(a)locusonus.org ______________________________________________ * To listen to the streams already available click here: http://nujus.net/~locusonus/site/streams/index.html * To download a PD patch and start streaming click here : (password required: contact support(a)locusonus.org) http://nujus.net/~locusonus/site/streams/download.html * To see video documentation of our previous presentations and to find out more about Locus Sonus in general, click here: http://locusonus.org/ ______________________________________________ NEXT PUBLIC EVENTS Presentations start from 15th to 30th of August in various performance and installation situations, starting with DIGIT Delaware Delaware Valley Arts Alliance & Roebling Bridge Environmental Arts and LMCC (Lower Manhattan Cultural Council) in partnership with THE THING Inc. (New York) with the support of Étant Donnés, The French-American Fund for Contemporary Art. Presentations continue in the fall with an installation during the Arborescence festival in Aix-en-Provence, France, and an installation performance at GMEM, Marseille France. Festival DIGIT: http://www.artsalliancesite.org/programs/digit_06.html LMCC: http://www.lmcc.net/ THE THING: http://bbs.thing.net/ Arborescence: http://www.arborescence.org/rubrique.php3?id_rubrique=3 GMEM: http://www.gmem.org/ ______________________________________________ TECHNICAL DOC We presume that members of the PD list will have no problem in opening the patch and streaming however just in case here are some technical tips: To Start Streaming You will Need : * a PC or Mac dedicated to the stream (an old 450 MHz machine should do). * a sound card recognized by your operating system. * a microphone (3$ radioshack mike is fine). * streaming software (we propose that you download our PD patch http://nujus.net/~locusonus/site/streams/download.html (ask to support(a)locusonus.org to obtain the password) and run it using PureData : http://at.or.at/hans/pd/installers.html that way you can customize your stream (for osX, Windows and Linux). We recommend that you use this Hans Christoph Steiner's extended version which includes the necessary ogg vorbis libraries. * a high speed internet connection and a network router. We obtained the good results using the Dyne:bolic Linux distribution http://www.dynebolic.org/ The advantage being thats it's a liveCD (so you don't have to install the system) and that PD and all the necessary externals are already installed. You might run into difficulties if the system doesn't recognize the PCs built in sound card in which case the easiest option is to find an old soundblaster card and disactivate the built-in card in the bios. It's important for us to get a wide range of soundscapes and social situations, remember that urban sound is pretty similar around the western world so you might want to chose to place your microphone so as to capture interesting or unique aspects of your environment and also to listen to the other current streams to caracterize yours. We are also finding that in most circumstances it is preferable to customize the patch, sometimes a little filtering is all thats needed (as for example: port.ogg) but we've also built a sampling patch which records and plays back recent sound events continually updating its database (as for example: cap15.ogg). Listen to the current streams: http://nujus.net/~locusonus/site/streams/index.html Travel and listen to the current streams with a map: http://nujus.net/~locusonus/site/streams/map.html ____________________________ Locus Sonus Lab Nicolas Bralet, Jerome Joy, Esther Salmona, Peter Sinclair, Lydwine van der Hulst http://locusonus.org/ : ____________________________

First instrument
by Tas Pas 26 Jul '06

26 Jul '06

Hi list, It is 2 weeks (more or less) since I started using pd... It is easier than I thought, though, looking to other people's work, I reckon that I have a long way till I built my instruments for music making. Anyway, I have attached my first instrument here. It uses a sine osc and can be played via the keyboard's numpad (1-8). On load you have a c minor harmonic scale loaded but you can switch to minor (upwards) melodic and major scale via 3 message buttons. Using numpad's 9 and .(del) keys you can switch octaves. Using the a,b,c,d,e,f,g keys, you can transport to the omonymous scale. Using the 0 key, you mute the instrument. Not quite much, but it is a begining... Any advice, or guidance will be highly appreciated. Regards, Terumi --------------------------------- ΓΓ±Γ§Γ³Γ©Γ¬Γ―Γ°Γ―Γ©Γ₯ΓΓ΄Γ₯ Yahoo!

[PD-announce] nightly auto-builds are functional
by Hans-Christoph Steiner 26 Jul '06

26 Jul '06

You can now get 4 different GNU/Linux nightly builds here: http://128.238.56.50/auto-build http://puredata.org/dev/PdLab I hope to get Mac OS X and Windows builds up soon too. These machines can also be used as a development test before for creating native packages. If anyone wants to step up and take on OS-native packages, then I can give them shell access. .hc _______________________________________________ PD-announce mailing list PD-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

Where do PDers gather in Vienna?
by Breitschädel Hannes 25 Jul '06

25 Jul '06

Hi List! I'd like to get in personal contact with people from vienna working with pd, sharing ideas, socializing etc... I live in Vienna and started with PD 3 years ago, I am using it to build signalprocessing prototypes. How many users are there in vienna? Is there some kind of periodical meetings or a location where PDers gather? cheers, Hannes ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.

GEM: video analysis
by Florian Walter 25 Jul '06

25 Jul '06

Hallo, I would like to do some video analysis to control the playback of audio files. pix_movement and pix_blob work quite well, but now I would like to go into details and have some questions: - How can I apply a color filter to an image? I would like to distinguish the movement of different colors... - Is there an object that returns the total brightness of an image? Or are there other possibilities to detect the "amount" of movment in a video? (I read about pix_mean_color in the archives but I can't find it in gem 0.90.1...) - I would like to recognize whether big blocks of a single color or fine noise-like structures are moving. Downsamling might be a good solution to get away the fine structures and to reduce the number of pixels inside of a colored block that are not recognized as moving. pix_resize didn't change anything (are there any parameters I can pass to that object?) and needs lots of computing power... Any ideas how to solve this problem? Thank you for any ideas or suggestions! I am doing my first steps with pd (and image processing), so probably I have overlooked several things... ciao, Florian
