Appending soundfiler external?
by Fred Jan Kraan 01 Nov '13

01 Nov '13

Is there an external which allows writing arrays to sound files (WAV, AIF, ..), with the ability to append to existing files? It would be much like soundfiler but with an additional "append" message. Soundfiler overwrites the file on a "write" message. It is possible as I succeeded in adding an "append" argument to soundfiler object. But if there is already such an object I can spare myself the trouble of making it more complete and robust. This is for a project that tries to clean up existing sound files by reading them chunk by chunk into an array, processes the array contents and writing the result to a different file. This not necessary in real time, as the files are large (+/- 1 hour of CD-quality audio). Fred Jan

Oculus Rift shader in pd/Gem
by Michael Mihocic 01 Nov '13

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... Br, Michael -------- Original-Nachricht -------- Betreff: [GEM-dev] Fwd: Re: Oculus Rift distortion/support Datum: Sun, 27 Oct 2013 18:51:33 +0100 Von: Michael Mihocic <michael.mihocic(a)oeaw.ac.at> An: <gem-dev(a)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? Br, Michael

[PD-announce] [ot] the MS and PhD degrees in music technology at Georgia Tech
by Jason Freeman 01 Nov '13

01 Nov '13

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 systems 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).
