Re: [PD] audio output AND input with the Rpi?
Dear all, I just took a quick look at the page on puredata.info and noticed that my soundcard (E-mu 0404 USB) is mentioned as apparently [working]. For clarity's sake i think it would be good to modify the page a bit so that it's mentioned in the working soundcards. It's fully functional as far as i can tell (it works in duplex at 44100 Hz with one input) and has been since the beginning on the RPi without any slowing down of the USB speed. I can even prove it with a video (http://www.youtube.com/watch?v=NwJNeouLqgQ) ! Problem is, i don't know how to edit the page...

[PD] Oculus Rift shader in pd/Gem
Hy Cyrille,
based on your example I could implement the Rift shadering and I can
render the left and right eye seperatly. Thank you once again!
But the two shadered images (left and right) are behind each other and I
cannot use translateXYZ (x-axis translation) to move them to their
sides!? Do you have any idea?? The attached example (rift_example.pd)
includes more comments and is probably a better explanation...

Von:Michael Mihocic michael.miho...@oeaw.ac.at
An: gem-...@iem.at
Hy Cyrille,
thank you again for your quick reply!!
Good idea, I also replied to the Gem list! (I'm not registered at the pd
list...)
(Sorry, if someone might be annoyed about my attachments...)
Attached you can find my progress so far but I have to mention that my
scripts are still under construction - and not only the parameters far
from optimized ;-)
My example consists of:
- rift_list.pd- is the pd patch to be started, follow the
instructions on top of the file
- riftshader.pd is used for the distortion parameters, when using the
shaders:
- r4.frag/r4.vert are the shader files
- test.jpg is just any test file which will be distorted
I'm not using gemframebuffers in my patch. Currently I am simply loading
2 times the same image and processing the barrel distortions on each
half of the image, left and right.
But as I described below, our actual world does not consist of one image
but of many objects (spheres, cubes, lines,...) within a big sphere, and
the user can rotate his head inside the sphere. ((tracking will not be
done with Oculus Rift tracker))
- theoretically, my perfect solution would be to apply the distortion
to the entire stereo gemwin somehow!? ;-)
Following the idea of your patch and introducing gemframebuffers, do you
think I can realize it that way:
- every object needs to be rendered twice instead of once, and in a
framebuffer, sent to the abstraction gemhead_rift
- the barrel distortion is applied in the abstraction gemhead_rift,
the parameters depending on left or right
- instead of using stereo, I create a wider window and add
X-axis-translation
Do you think it should work that way?

Re: [PD] Oculus Rift shader in pd/Gem
hello Michael, translate did not work because the shader did not use the transformation matrix (that translate, scale etc are modifying). the shader use texture corrdinate as vertex position. see this line in the vert shader : gl_Position = gl_Vertex; usually you have somthing like : gl_Position = ftransform(); cheers c Le 31/10/2013 16:31, Michael Mihocic a écrit : Hy Cyrille, based on your example I could implement the Rift shadering and I can render the left and right eye seperatly.

[PD] [PD-announce] [ot] the MS and PhD degrees in music technology at Georgia Tech
Georgia Tech is now accepting applications for the MS and PhD programs in music technology for matriculation in August 2014. All PhD students, and a limited number of MS students, receive graduate research assistantships that cover tuition and pay a competitive monthly stipend. The deadline for applications is January 31, 2014. The MS in Music Technology is a two-year program that instills in students the theoretical foundation, technical skills, and creative aptitude to design the disruptive technologies that will enable new modes of music creation and consumption in a changing industry. Students take courses in areas such as music information retrieval, music perception and cognition, signal processing, interactive music, the history of electronic music, and technology ensemble. They also work closely with faculty on collaborative research projects and on their own MS project or thesis. Recent students in the program have worked and/or interned at companies such as Apple, Avid, Dolby, Bose, Gracenote, Rdio, Sennheiser, Ableton, Echo Nest, and Smule, and gone on to PhD studies. Applicants are expected to have an undergraduate degree in music, computing, engineering, or a related discipline, and they should possess both strong musical and technical skills. Students in the PhD program in Music Technology pursue individualized research agendas in close collaboration with faculty in areas such as interactive music, robotic musicianship, music information retrieval, digital signal processing, mobile music, network music, and music education, focusing on conducting and disseminating novel research with a broad impact. PhD students are also trained in research methods, teaching pedagogy, and an interdisciplinary minor field as they prepare for careers in academia, at industry research labs, or in their own startup companies. PhD applicants are expected to hold a Masters degree in music technology or from an allied field, such as computing, music, engineering, or media arts and sciences. All applicants must demonstrate mastery of core masters-level material covered in Music Technology, including music theory, performance, composition, and/or analysis; music information retrieval; digital signal processing and synthesis; interactive music syst ems design; and music cognition. Both the MS and PhD programs are housed within the School of Music at Georgia Tech, in close collaboration with the Georgia Tech Center for Music Technology (GTCMT). The GTCMT is an international center for creative and technological research in music, focusing on the development and deployment of innovative musical technologies that transform the ways in which we create and experience music. Its mission is to provide a collaborative framework for committed students, faculty, and researchers from all across campus to apply their musical, technological, and scientific creativity to the development of innovative artistic and technological artifacts. Core faculty in the music technology program include Gil Weinberg (robotic musicianship, mobile music, and sonification), Jason Freeman (participatory and collaborative systems, education, and composition), Alexander Lerch (music information retrieval and digital signal processing), Timothy Hsu (acoustics), Frank Clark (multimedia and network music), and Chris Moore (recording and production).
