CFP: Audio-graphic Modeling and Interaction @ NIME 2011, May 29 2011

by Diemo Schwarz

Call for Abstracts, please forward: Audio-graphic Modeling and Interaction Workshop @ NIME 2011, Oslo, Norway Sunday, May 29: 1PM-4PM. This workshop focuses on recent advances and future prospects in audio-graphic scenes modeling and rendering. The convergence of the audio and graphic communities is fostered by the increase in computational resources, by cognitive studies on cross-modal perception, and by the industrial needs for realistic audio scenes. Audio-graphic research is spreading in areas such as games, architecture, urbanism, information visualization, or interactive artistic digital media. We will focus on the representation, the interaction, the rendering, and the perception of scenes in which the audio and graphical components are clearly identified and combined (in contrast to standard multimedia video streams). Accepted abstracts will invited to submit an extended version to a special issue of the Springer Journal on Multimodal User Interfaces (JMUI) Detailed information about the workshop can be found here: http://www.topophonie.fr/event/1 Registration to the workshop and NIME conference can be found here: http://www.nime2011.org/registration/ Call for Abstracts ------------------ Abstracts (max. 1 A4/Letter page, 12 points, PDF format) on the topics of the workshop should be sent before April 20 to Hui Ding, LIMSI-CNRS (Hui.Ding(a)limsi.fr) The submissions will be reviewed by a program committee and accepted communications will be given at the workshop. The authors will be notified latest April 29, 2011. Important Dates --------------- * April 20, 2011: Abstract Submission Deadline * April 29, 2011: Notification of Acceptance * May 29, 2011: Workshop. Program Chairs -------------- Roland Cahen, ENSCI-les Ateliers Christian Jacquemin, LIMSI-CNRS & University Paris Sud 11 Diemo Schwarz, IRCAM Hui Ding, LIMSI-CNRS & University Paris Sud 11 Program committee ----------------- Brian Katz, LIMSI-CNRS, France Cécile Picard-Limpens, HEM, Geneva and UMONS, Belgium Lauri Savioja, Aalto University School of Science, Finland Topics in detail ---------------- Beyond the question traditionally addressed in multimedia, the workshop will cover recent advances in audio-graphic scene modeling such as: * - joint representation of sound and graphic spaces and objects, * - rendering optimization for audio-graphic scenes: level of details, o . occlusion, o . masking, o . beam and ray tracing, o . shadowing, o . space subdivision, o . collisions... * - audio-graphic interface design, * - audio-graphic for virtual humans: o . audio-visual speech, o . cloth animation and sound rendering, o . steps, o . paralinguistic communication... * - sound and graphic spatialization, * - audio-graphic object rendering, and physically and geometrically driven sound rendering, * - cross- and bi-modal perceptual evaluations, * - audio-graphic information visualization: o . distortion, o . zooming and panning, o . filtering, o . immersive rendering, o . visual data sonification, o . interaction devices... * - interactive audio-graphic arts, * - industrial audio-graphic data: o . architectural acoustics, o . sound maps, o . urban soundscapes... * - platforms and tools for audio-graphic scene modeling and rendering, These areas are interdisciplinary in nature and inter-related. New advancements in each area will benefit the others. This workshop should attract young and senior researchers, artists, and corporates in the related fields together to exchange the latest developments and to point out current challenges and new directions. tags NIME, oslo, conference, workshop

[ANN] jack-stdout 1.0

by Robin Gareus

Hya, I've just brought jack-stdout up to scratch. jack-stdout captures audio from one or more JACK audio-ports and writes raw data to standard-output. It can write signed/unsigned 16/24bit integer and 32bit floating-point data, both big/little endian. * http://rg42.org/oss/jackstdout/ * git://rg42.org/jack-stdout example usage - live stream from JACK: jack-stdout system:capture_1 system:capture_2 \ | oggenc -r -R 48000 -B 16 -C 2 - \ | tee /tmp/recording.ogg \ | oggfwd -p -n "my live stream" localhost 5900 hackme live.ogg have fun, robin

[ANN] zynjacku-6

by Nedko Arnaudov

In this release: * Fixes and improvements that improve interoperability with these plugins: * The Composite Sampler * EQ10Q * Calf * Support the new dynamic manifest extension and thus NASPRO 0.2.90 * It is now possible to supply on commandline a regular expression instead of URI. The regexp must match only one URI. * Plugin GUI windows now have WM_WINDOW_ROLE set to "plugin_ui" (for WM kludges etc) * Various improvements in lv2 turtle rdf parsing * A commandline parsing bug that prevented use of state file is fixed * Better reporting and handling of ttl syntax errors * The plugin scanner got some speed an memory optimizations * It is now possible to build and use zynjacku on MacOSX * Windows of the generic GUIs are now smaller when the plugin is not dynparam one * The Author column is now named Maintainer to better match doap:maintainer semantics * Change installation layout to better suit Debian and hopefully other distros as well * In single plugin mode, exit if UI show failed * Properly handle scan when there are no lv2 plugins installed (patch by Orcan Ogetbil) https://bugzilla.redhat.com/show_bug.cgi?id=551480 * Fix syntax error exception. #15558 * When rack was being cleared, some plugin UI windows were not being closed. This bug was fixed. zynjacku is JACK based, GTK (2.x) host for LV2 synths. It has one JACK MIDI input port (routed to all hosted synths) and one (two for stereo synths) JACK audio output port per plugin. Such design provides multi-timbral sound by running several synth plugins. zynjacku is a nunchaku weapon for JACK audio synthesis. You have solid parts for synthesis itself and you have flexible part that allows synthesis to suit your needs. lv2rack is a host for LV2 effect plugins.

[ann] CAPS 0.4.5

by Tim Goetze

The C* Audio Plugin Suite reaches version 0.4.5. http://quitte.de/dsp/caps.html http://quitte.de/dsp/caps_0.4.5.tar.gz CAPS is a collection of refined LADSPA units covering a wide range of applications, from stompbox classics to experimental oscillators. CAPS is distributed as open source under the terms of the GNU Public License. -*- This release brings a new plugin, "Narrower", which reduces the perceived width of a stereophonic image. Frequent users of headphones will appreciate the increased subtlety of the listening experience as well as the reduced fatigue caused by "superstereo" recordings. Other than that, some minor bugs have been fixed and the accompanying PDF data sheet has been improved (frequency response plots now use log scale: http://quitte.de/dsp/caps-0.4.5.pdf ). The build configuration tool "configure.py" has been modified to handle python3's errant ways in graceful manner. Upgrading is recommended unless you have no need for the new plugin and the current version is working fine for you. -*- Enjoy, and thank you for using CAPS, Tim

NASPRO 0.2.90 released

by Stefano D'Angelo

Hi all, I'm glad to announce the release of NASPRO 0.2.90. NASPRO (http://naspro.atheme.org/) is meant to be a cross-platform sound processing software architecture built around the LV2 plugin standard (http://lv2plug.in/). The goal of the project is to develop a series of tools to make it easy and convenient to use LV2 for sound processing on any (relevant) platform and for everybody: end users, host developers, plugin developers, distributors and scientists/researchers. This release is a total redesign/rewrite that more or less reimplements the features of the previous release, but in a much cleaner and maintainable way. It includes: * NASPRO core: the portable runtime library at the bottom of the architecture; * NASPRO Bridge it: a little helper library to develop insert-your-API-here to LV2 bridges; * NASPRO bridges: a collection of bridges to LV2 which, once installed, allow you to use plugins developed for other plugin standards in LV2 hosts. In particular, the NASPRO bridges collection includes two bridges: a LADSPA (http://www.ladspa.org/) 1.1 and a DSSI (http://dssi.sourceforge.net/) 1.0.0/1.1.0 bridge. All of the code is released under the LGPL 2.1 (http://www.gnu.org/licenses/lgpl-2.1.html) license. More information is available on the project's website. Enjoy! Stefano D'Angelo
