[LAA] [ANN] JACK 0.121.0 + D-Bus (jackdbus)

by Nedko Arnaudov

Apart from the usual jackdbus addition, this release contains fix for the missing control.h file in the vanilla tarball. This release provides both the new jackd.py (D-Bus bound and available in the vanilla tarball) and jackdbus. Tarball containing D-Bus patched jack 0.120.2 is available here: http://nedko.arnaudov.name/soft/jack/dbus/ http://nedko.arnaudov.name/soft/jack/dbus/jack-audio-connection-kit-dbus-0.… http://nedko.arnaudov.name/soft/jack/dbus/jack-audio-connection-kit-dbus-0.… A patch against vanilla 0.121.0 is available here: http://nedko.arnaudov.name/soft/jack/dbus/jack-audio-connection-kit-0.121.0… http://nedko.arnaudov.name/soft/jack/dbus/jack-audio-connection-kit-0.121.0… After applying the patch you have to run autoreconf. D-Bus modifications add optional autodetected support for the D-Bus based server control system. D-Bus is object model that provides IPC mechanism. D-Bus supports autoactivation of objects, thus making it simple and reliable to code a "single instance" application or daemon, and to launch applications and daemons on demand when their services are needed. * Simplified single thread model for control and monitor applications. Various D-Bus language bindings make it trivial to write control and monitor applications using scripting languages like Python, Ruby, Perl, etc.. * JACK has log file (~/.log/jack/jackdbus.log) that is available for inspection even when autoactivation happens because of first JACK application is launched. * There is real configuration file used to persist settings that can be manipulated through configuration interface of JACK D-Bus object. * Improved graph inspection and control mechanism. JACK graph is versioned. Connections, ports and clients have unique (monotonically increasing) numeric IDs. * High level abstraction of JACK settings. Allows applications that can configure JACK to expose parameters that were not known at compile (or tarball release) time. Currently there are some minor differences between jack1 jackdbus and jack2 jackdbus: * There is no parameter constraints support (no enums and no ranges) * Settings file (in ~/.config/jack/) is conf-jack1.xml instead of conf.xml, because jack1 and jack2 settings and not really compatible. When configured with D-Bus support, jack_control is installed. jack_control is simple commandline interface for jackdbus. Other tools that can communicate with JACK through D-Bus: * LADItools (tray icon, configuration, etc.) * Patchage (and lpatchage too) * LASH 0.6.x * ladish * QJackCtl -- Nedko Arnaudov <GnuPG KeyID: 5D1B58ED>

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

by Diemo Schwarz

Call for Abstracts, please forward: Versatile Sound Models for Interaction in Audio–graphic Virtual Environments: Control of Audio-graphic Sound Synthesis Workshop @ Conference on Digital Audio Effects DAFx-11 Friday September 23, 2011 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. Accepted abstracts will be invited to submit an extended version to a special issue of the Springer Journal on Multimodal User Interfaces (JMUI) or SpringerOpen EURASIP Journal on Audio, Speech, and Music Processing. Detailed information about the workshop can be found here: http://www.topophonie.fr/event/3 http://dafx11.ircam.fr/?page_id=224 The workshop is free for attendants of the DAFx conference and for non-DAFx-attendants by invitation. Registration to the DAFx conference can be found here: http://dafx11.ircam.fr Call for Abstracts ------------------ Abstracts (max. 1 A4/Letter page, PDF format) on the topics of the workshop should be sent by July 17 to Diemo Schwarz (schwarz(a)ircam.fr) The submissions will be reviewed by a program committee and accepted communications will be given at the workshop. The authors will be notified at the latest end of July, 2011. Important Dates --------------- * July 17, 2011: Abstract Submission Deadline * July 31, 2011: Notification of Acceptance * September 23, 2011: Workshop Program Chairs -------------- Roland Cahen, ENSCI-les Ateliers Diemo Schwarz, IRCAM Christian Jacquemin, LIMSI-CNRS & University Paris Sud 11 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) 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. -- Diemo Schwarz, PhD -- http://diemo.concatenative.net Real-Time Music Interaction Team -- http://imtr.ircam.fr IRCAM - Centre Pompidou -- 1, place Igor-Stravinsky, 75004 Paris, France Phone +33-1-4478-4879 -- Fax +33-1-4478-1540

[LAA] io GNU/Linux .... a multimedia live system based on Debian SID

by MK aka El Doctor

Hi there :) Better later than never... just wanted to let you know about the existence of a live dvd/usb that, I hope, may interess some linux audio adictos here :) "io GNU/Linux is a live system that turns almost any computer into a professional multimedia workstation. It includes a real-time enabled kernel and a great collection of free software for all uses (sound, video, graphics, internet and more)." http://sourceforge.net/projects/io-gnu-linux/ It's based on Debian SID and built whith the Debian Live tools. JACK2 combined with Ladish/Laditools is used as default sound server (you may need first to set up phonon to prefer JACK over Alsa for KDE related apps) Don't hesitate to give it a try and for sure, any feedback more than welcome. Hope this helps, cheers ;) MK
