SUMMARY:LAC2012 - INScore - An Environment for the Design of Live Music Scores
DESCRIPTION:INScore is an open source framework for the design of interactive\, augmented\, live music scores. Augmented music scores are graphic spaces providing representation\, composition and manipulation of heterogeneous and arbitrary music objects (music scores but also images\, text\, signals...)\, both in the graphic and time domains. \nINScore includes also a dynamic system for the representation of the music performance\, considered as a specific sound or gesture instance of the score\, and viewed as signals. \nIt integrates an event based interaction mechanism that opens the door to original uses and designs\, transforming a score as a user interface or allowing a score self-modification based on temporal events. \nThis paper presents the system features\, the underlying formalisms\, and introduces the OSC based scripting language.

SUMMARY:LAC2012 - The IEM Demosuite\, a large-scale jukebox for the MUMUTH concert venue
DESCRIPTION:In order to convey the manifold possibilies of surround sound design in the new MUMUTH concert hall to a broad audience we present the development of an easy to use application which allows to run and interact with several audio demonstrations from a mobile computing device. An extensible number of such demonstrations using the large-scale and variable loudspeaker hemisphere in the hall are controlled with a user interface optimized for touch-sensitive input. Strategies for improving the operating safety as well as the introduction of a client/server model using the programming language Pure Data are discussed in the context of use with a 3D Ambisonics rendering server\, both implemented using the Linux operating system.

SUMMARY:LAC2012 - Network distribution in music applications with Medusa
DESCRIPTION:This paper introduces an extension of Medusa\, a distributed music environment\, that allows an easy use of network music communication in common music applications. Medusa was firstly developed as a Jack application and now it is being ported to other audio APIs as a try of make network music more accessible. The APIs chosen were LADSPA\, LV2 and Pure Data external. This new project approach required a complete review of the tool's architecture. As result of this development\, possibilities of using network music as a plugin in well known environments will be presented and commented.

SUMMARY:LAC2012 - pd-faust: An integrated environment for running Faust objects in Pd
DESCRIPTION:This paper introduces pd-faust\, a library for running signal processing modules written in Grame's functional dsp programming language Faust in Miller Puckette's graphical computer music environment Pure Data a.k.a. Pd. pd-faust is based on the author's faust2pd script which generates Pd GUIs from Faust programs and also provides the necessary infrastructure for running Faust dsps in Pd. pd-faust combines this functionality with its own Faust plugin loader\nwhich makes it possible to reload Faust dsps while a patch is running. It also adds automatic configuration of MIDI and OSC controller assignments\, as well as OSC-based automation features.

SUMMARY:LAC2012 - A Toolkit for the Design of Ambisonic Decoders
DESCRIPTION:Implementation of Ambisonic reproduction systems is limited by the number and placement of the loudspeakers. In practice\, real-world systems tend to have insufficient loudspeaker coverage above and below the listening position. Because the localization experienced by the listener is a nonlinear function of the loudspeaker signals it is difficult to derive suitable decoders analytically. As an alternative it is possible to derive decoders via a search process in which analytic estimators of the localization quality are evaluated at each search position. We discuss the issues involved and describe a set of tools for generating optimized decoder solutions for irregular loudspeaker arrays and demonstrate those tools with practical examples.

DESCRIPTION:The tool is not a synthesizer - it is a Synth-A-Modeler! This paper introduces the Synth-A-Modeler compiler\, which enables artists to synthesize binary DSP modules according to mechanical analog model specifications. This open-source tool promotes modular design and ease of use. Leveraging the Faust DSP programming environment\, an output Pd\, Max/MSP\, SuperCollider\, VST\, LADSPA\, or other external module is created\, allowing the artist to "hear" the sound of the physical model in real time using an audio host application.

SUMMARY:LAC2012 - Studio report: Linux audio for multi-speaker natural speech technology
DESCRIPTION:The Natural Speech Technology (NST) project is the\nUK's flagship research programme for speech recognition research in natural environments. NST is a collaboration between Edinburgh\, Cambridge and Sheffield\nUniversities\; public sector institutions the BBC\, NHS\nand GCHQ\; and companies including Nuance\, EADS\,\nCisco and Toshiba. In contrast to assumptions made\nby most current commercial speech recognisers\, natural environments include situations such as multiparticipant meetings\, where participants may talk over\none another\, move around the meeting room\, make\nnon-speech vocalisations\, and all in the presence of\nnoises from office equipment and external sources such\nas traffic and people outside the room. To generate\ndata for such cases\, we have set up a meeting room /\nrecording studio equipped to record 16 channels of audio from real-life meetings\, as well as a large computing cluster for audio analysis. These systems run on free\,\nLinux-based software and this paper gives details of\ntheir implementation as a case study for other users\nconsidering Linux audio for similar large projects.

SUMMARY:LAC2012 - GRE (Graduate Rhythmic Examination)
DESCRIPTION:G.R.E. (Gradute Rhythmic Examination) is a piece that involves a computer-administered "test" in the form of a series of short rhythmic exercises that the percussionist plays. After playing each exercise\, the computer "grades" the performer on her ability to play the example correctly and then creates a new piece of music for her to play. As the test progresses\, the level of difficulty of new questions is guaged by the performance ability of the percussionist.

SUMMARY:LAC2012 - Field Report II - Capturing Chroma XII by Rebecca Saunders
DESCRIPTION:In 2010\, the author had the privilege to capture a performance of Rebecca Saunders' intricately spatial composition Chroma XII in fully periphonic third-order Ambisonics. The production grew to considerable complexity and provides an excellent showcase for a large-scale Ambisonic production using free software. This workshop discusses the artistic motivation (or even necessity) of using a with height recording method for the work at hand.\n\nAfter a short description of the composition\, its instrumentation and the performance space\, the microphone and mixing techniques are being\ndiscussed in detail\, including hardware and software toolchains\, postproduction workflow\, and lessons learned from subsequent replays on various systems.\n\nThis is a follow-up to a workshop presented at LAC 2010 in Utrecht.

SUMMARY:LAC2012 - Controlling adaptive resampling
DESCRIPTION:Combining audio components that use incoherent sample clocks requires\nadaptive resampling - the exact ratio of the sample frequencies is not\nknown a priori and may also drift slowly over time. This situation\narises when using two audio cards that don't have a common word clock\,\nor when exchanging audio signals over a network. Controlling the \nresampling algorithm in software can be difficult as the available\ninformation (e.g. timestamps on blocks of audio samples) is usually\ninexact and very noisy. This paper analyses the problem and presents \na possible solution.

SUMMARY:LAC2012 - From Jack to UDP packets to sound\, and back
DESCRIPTION:The Mamba Digital Snakes are commercial products created by Network Sound\, that are used in pairs to replace costly analog cable snakes by a single ethernet cable. A pair of boxes can send and receive up to 64 channels at 48KHz sampling rate packed with 24 bit samples. This paper describes the evolution of jack-mamba\, a small jack client that can send and receive UDP packets to/from the box through a network interface and basically transforms it into a high channel count soundcard.

SUMMARY:LAC2012 - Minivosc - a minimal virtual oscillator driver for ALSA (Advanced Linux Sound Architecture)
DESCRIPTION:Understanding the construction and implementation of sound cards (as examples of digital audio hardware) can be a demanding task\, requiring insight into both hardware and software issues. An important step towards this goal\, is the understanding of audio drivers and how they fit in the flow of execution of software instructions of the entire operating system.\n\nThe contribution of this project is in providing sample open-source code\, and an online tutorial [1] for a mono\, capture-only\, audio driver which is completely virtual\; and as such\, does not require any soundcard hardware. Thus\, it may represent the simplest form of an audio driver under ALSA\, available for introductory study\; which can hopefully assist with a gradual\, systematic understanding of ALSA drivers' architecture and audio drivers in general.

SUMMARY:LAC2012 - An Open Source C++ Framework for Multithreaded Realtime Multichannel Audio Applications
DESCRIPTION:An open source C++ framework is introduced which facilitates the implementation of multithreaded realtime audio applications\, especially ones with many input and output channels. Block-based audio processing is used.\n\nThe framework is platform-independent and different low-level audio backends can be used for both realtime and non-realtime operation. Support for further backends can be added easily.

SUMMARY:LAC2012 - Using the beagleboard as hardware to process sound
DESCRIPTION:This paper describes the implementation of diverse layers of code to enable an open source embedded hardware device to run audio processing pure data patches. The evolution of this implementation is reviewed describing different approaches taken by the authors in order to find optimal software and hardware settings. Although some problems are detected when running specific patches\, the system has a conjunction of features that are relevant for the floss audio community.
