Call for Participation: Versatile Sound Models for Interaction in Audio–graphic Virtual Environments Workshop at DAFx-11, Ircam, Paris

by Diemo Schwarz

Call for Participation, please forward: Versatile Sound Models for Interaction in Audio–Graphic Virtual Environments: Control of Audio-graphic Sound Synthesis Satellite Workshop @ Conference on Digital Audio Effects DAFx-11 http://dafx11.ircam.fr/?page_id=224 Friday September 23, 2011, 9h00–13h00 at Ircam, Paris The use of 3D interactive virtual environments is becoming more widespread in areas such as games, architecture, urbanism, information visualization and sonification, interactive artistic digital media, serious games, gamification. The limitations in sound generation in existing environments are increasingly obvious with current requirements. This workshop will look at recent advances and future prospects in sound modeling, representation, transformation and synthesis for interactive audio-graphic scene design. Several approaches to extending sound generation in 3D virtual environments have been developed in recent years, such as sampling, modal synthesis, additive synthesis, corpus based synthesis, granular synthesis, description based synthesis, physical modeling... These techniques can be quite different in their methods and results, but may also become complementary towards the common goal of versatile and understandable virtual scenes, in order to cover a wide range of object types and interactions between objects and with them. The purpose of this workshop is to sum up these different approaches, present current work in the field, and to discuss their differences, commonalities and complementarities.

Program Chairs -------------- Diemo Schwarz, IRCAM Roland Cahen, ENSCI-les Ateliers Hui Ding, LIMSI-CNRS & University Paris Sud 11 Program committee ----------------- Nicolas Tsingos (Dolby Laboratories) Lonce Wyse (National University of Singapore) Andrea Valle (University of Torino) Hendrik Purwins (University Pompeu Fabra) Thomas Grill (Institut für Elektronische Musik IEM, Graz) Charles Verron (McGill University, Montreal) Cécile Le Prado (Centre National des Arts et Metiers CNAM) Christian Jacquemin (LIMSI-CNRS & University Paris Sud 11) Topics in detail ---------------- Which other and better alternatives to traditional sample triggering do exist to produce comprehensive, flexible, expressive, realistic sounds in virtual environments? How to produce rich interaction with scene objects such as physically informed models for contact and friction sounds etc? How to edit and structure audio–graphic scenes otherwise than mapping one event to one sound? There is no standardized architecture, representation and language for auditory scenes and objects, as is OpenGL for graphics. The workshop will treat higher level questions of architecture and modeling of interactive audio-graphic scenes, down to the detailed question of sound modeling, representation, transformation and synthesis. These questions cannot be detached from implementation issues: novel and hybrid synthesis methods, comparison and improvement of existing platforms, software architecture, plug-in systems, standards, formats, etc. New possibilities regarding the use of audio descriptors and dynamic access to audio databases will also be discussed. Beyond these main questions, the workshop will cover other recent advances in audio-graphic scene modeling such as: * audio-graphic object rendering, and physically and geometrically driven sound rendering, * interactive sound texture synthesis, based on signal models, or physically informed * joint representation of sound and graphic spaces and objects, * sound rendering for audio-graphic scenes: * level of detail, which is a very advanced concept in graphics, but is rarely treated in audio. * representation of space and distance, * masking and occlusion of sources, * clustering of sources * audio-graphic interface design, * sound and graphic localization, * cross- and bi-modal perceptual evaluations, * interactive audio-graphic arts, * industrial audio-graphic data: * architectural acoustics, * sound maps, * urban soundscapes... * platforms and tools for audio-graphic scene modeling and rendering, These areas are interdisciplinary in nature and interrelated. New advancements in each area will benefit the others. This workshop will allow to exchange the latest developments and to point out current challenges and new directions.

New soft synth: The Newtonator v0.5.1

by Michael Bechard

Brand new LV2 plugin soft synth here. The Newtonator (v0.5.0) features: * LV2-compliant synth plugin * Simple, easy-to-use GTK-based GUI * 3-note polyphony (err, um, until I can do some serious optimization) * "Unique" synthesis algorithm (Tuna Pagan Fellowship) The Newtonator specializes in making crazy, harsh sounds, so if you're looking for some sounds to produce the next Yanni album, keep looking. Please refer to the user manual (http://newtonator.sourceforge.net/manual/index.html) for more gory details. Download: http://sourceforge.net/projects/newtonator/files/newtonator-0.5.0.tar.gz/do… NOTE: This plugin was written against the excellent libraries included in the lv2-c++-tools package written by Lars Luthman. However, as of v1.0.4, the GUI library only supports rev. 2 of the LV2 specification, so it may have problems on newer hosts (though I have done some (very) preliminary testing against Ardour3 and it seems to work ok). Alpha testing mostly done against zynjacku and Elven (comes with ll-plugins package) hosts. This puppy's in beta, so feel free to get in touch with me at the project forum (https://sourceforge.net/projects/newtonator/forums/forum/1820765) or submit a bug if needed. Thanks, and have fun.

[ANNOUNCE] FluidSynth 1.1.4 released!

by David Henningsson

In short, version 1.1.4 of FluidSynth brings us: * Several improvements and fixes to the CMake build system, especially for Mac OS X * Several bug fixes to the engine, notably quite a few which could cause FluidSynth to sound bad in some cases. * API additions, that make it possible to - load MIDI files from memory - to inspect/modify MIDI events as they are being played from a MIDI file - to change channels between melodic and drum mode - and to silence all notes in one command. * Improvements to the CoreAudio driver A more detailed list of changes is available at https://sourceforge.net/apps/trac/fluidsynth/wiki/ChangeLog1_1_4 Looking back at the changes, I'm feeling a little proud today. One of the reasons for feeling proud, is that we have more than one new contributor: people who have taken the step to actually work with the code, improve it, and create non-trivial patches with new functionality in it. That is a good foundation for the future and I hope all contributors feel welcomed and properly attributed. Also, the improvements/fixes to the build system is worth a special note (thanks Pedro!), I was surprised to see so many of them! And finally, we've managed to close several long standing bugs, which makes me feel that this release will be stable and enjoyable for a lot of people, with less annoyances than ever. (Thanks to the jOrgan folks for the test run!) Now, enjoy the release, and last but not least - make sure you make some really great music with it! :-) (Can't wait for your distro to package it up for you? You can download the tarball from SourceForge: https://sourceforge.net/projects/fluidsynth/ ) On behalf of the FluidSynth developer team, David Henningsson

by Mark Hills

I'm pleased to announce the 1.0 release of xwax -- DJ software for Linux. http://www.xwax.co.uk/ http://www.xwax.co.uk/releases/xwax-1.0.tar.gz The key changes since v0.9 are: * Changing of timecode at runtime * Improved parsing of vinyl track numbers * Bug fix: affecting multiple decks with different sample rates * Optimise timecode error checking during scratching xwax is open-source vinyl emulation software for Linux. It allows DJs and turntablists to playback digital audio files (MP3, Ogg Vorbis, FLAC, AAC and more), controlled using a normal pair of turntables via timecoded vinyls. It's designed for both beat mixing and scratch mixing. Needle drops, pitch changes, scratching, spinbacks and rewinds are all supported, and feel just like the audio is pressed onto the vinyl itself. The focus is on an accurate vinyl feel which is efficient, stable and fast. -- Mark
