edit IEM slider color
by tim vets 17 Dec '10

17 Dec '10

Hi all, I was trying to get a slider ( [hsl] ) to change color gradually as you drag it to the right. I'm using the RGB color subpatch from the slider help patch (inside subpatch 'editing') The strange thing is: when I drag the slider itself, it doesn't follow the RGB values, but it jumps between colors (the color presets I believe ?). When I use another slider to change the color of the first slider it does work... Any idea why? (see attached patch) gr, Tim

mobile device audio developer position
by Florian Grond 17 Dec '10

17 Dec '10

forewarding jobposting Montreal area: The Shared Reality Lab at McGill University is hiring a qualified developer for our "In Situ Audio Services" (ISAS) project. This involves developing spatialized audio rendering on mobile devices for the blind community, providing them with an enhanced sense of location awareness and an ability to actively explore their surroundings. The project is funded by the Minstère des services gouvermentaux and Google Research. The developer will start from our initial audio rendering software, written in Pd, running in the ZenGarden library on the iPhone platform, and augment this with parameterized control from the application, being developed in Objective C. Additional tasks will involve adding content to and querying our geospatial database, and managing the polyphonic audio sources that may be driven from a combination of text-to-speech, pre-stored files, network streaming, and local audio synthesis. Suitable candidates should have a strong programming background and experience with digital audio, in particular, real-time synthesis, spatialization, and sound design. Pd or MAX/MSP experience is important, and some familiarity with the iPhone SDK a significant benefit. Additional skills of value include technical writing, knowledge of CPU performance issues, and experimental design. The initial contract will be for six months, starting in January, or as soon as the slot is filled, and may be renewed. Salary is $40k per year, plus benefits. To apply, please send your CV and cover letter to sre-jobs(a)cim.mcgill.ca. -- -------------------------------------------------------------- F l o r i a n G R O N D PhD Student at Ambient Intelligence Group, CITEC Bielefeld University, Germany Universitaetsstrasse 21 - 23 33615 Bielefeld Tel.: 0049 521 106 12132 http://cit-ec.org http://grond.at --------------------------------------------------------------

consonant extraction using fft
by Ivica Ico Bukvic 16 Dec '10

16 Dec '10

Hi all, I have been playing with fft lately and was wondering if anyone has some pointers on how to extract consonants from vowels in human speech. I suspect it is detection of noisy signal that generally populates a much wider band of frequencies approaching some sort of filtered white noise (depending on the consonant) but am not sure as to what is the best strategy in isolating these at least somewhat reliably. Any ideas/pointers would be most appreciated.

question about import and some of the patches found in the manual
by Ivica Ico Bukvic 16 Dec '10

16 Dec '10

I tried opening a patch that used some of the rradical abstractions and found that in the latest svn snapshot pd-l2ork is based on, import fails to detect rradical (I thought that is what the meta file was supposed to do which is found inside rradical folder). More so, declare also fails to extend the path [declare -stdpath extra/rradical]. Either way ezdac~ (for instance) fails to be created and the only way one can create it is by creating it as rradical/ezdac~. Is this really how things should work in the latest release? If so, what is the purpose of import when practically no lib is built in pd-extended as a lib but rather as a set of objects?

no gui refresh on macbook pro with windows 7
by altern 16 Dec '10

16 Dec '10

hi I have a student who is running Windows 7 Ultimate on a Macbook Pro (not the latest model, this is about 3 years old machine). We are using PD extended 0.42-5 The GUI seems to stop refreshing at random times. For instance numbers output the right values but the value displayed does not get refreshed, so the interface does not seem to respond but actually the whole patch continues to work fine, it just does not display any changes. Restarting PD does not solve it, we have to restart the machine. We are working with GEM and I am wondering if something funny is going on with the graphics card. anyone knows a solution to this? thanks! enrike

0.43 nightly build
by Jonathan Wilkes 16 Dec '10

16 Dec '10

I took a stab at using the 0.43 nightly build on Lenny. The package installed ok and here's what I found: * when I first ran pd, I got an error because it was looking for pd-gui.tcl et al in /usr/tcl, which didn't exist. So I copied everything from the /usr/lib/pd-extended/tcl and then it worked. * created [f] on a canvas, right-clicked and did "Help". Couldn't find help patch. * tried Preferences->Path... and got a segfault. * no externals will create, no iemguis will create. -Jonathan

libraries in Pd-extended 0.43
by Hans-Christoph Steiner 16 Dec '10

16 Dec '10

One of the goals for Pd-extended 0.43 is to have all libraries have a maintainer, so Pd-extended isn't just a collection of lots of semi- working code. The end goal is to have a maintainer for all libraries that are included in Pd-extended. Here's the current list based on my knowledge: http://puredata.info/docs/LibrariesInPdExtended If you are interested in becoming the maintainer of any of the libraries that are currently lacking a maintainer, please add your name next to the library in question. Once you get the library up-to- date for Pd-extended, we can move it up to the "maintained" section on the top. Here's a rough sketch of the process of getting libraries into Pd-extended: http://puredata.info/docs/developer/GettingIntoPdextended .hc ---------------------------------------------------------------------------- All mankind is of one author, and is one volume; when one man dies, one chapter is not torn out of the book, but translated into a better language; and every chapter must be so translated.... -John Donne
