SUMMARY:LAC2011 - Semantic Aspects of Parallelism for SuperCollider
DESCRIPTION:Supernova is a new implementation of the SuperCollider server scsynth\, with a multi-threaded audio synthesis\n  engine. To make use of this thread-level parallelism\, two extensions has been introduced to the concept of the\n  SuperCollider node graph\, exposing parallelism explicitly to the user. This paper discusses the semantic inplications\n  of these extensions.

SUMMARY:LAC2011 - Particle synthesis - a unified model for granular synthesis
DESCRIPTION:The article describes an implementation of a\nsynthesis module capable of performing all known\ntypes of time based granular synthesis. The term\nparticle synthesis is used to cover granular\nsynthesis and all its variations. An important\nmotivation for this all-inclusive implementation is\nto facilitate interpolation between the known\nvarieties of particle synthesis. The requirements\,\ndesign and implementation of the synthesis\ngenerator is presented and discussed. Examples of\nindividual varieties are implemented along with a\nlonger interpolated sequence morphing between\nthem. Finally an application\, the Hadron Particle\nSynthesizer\, is briefly presented.

SUMMARY:LAC2011 - Poing Impératif: Compiling Imperative and Object Oriented Code to Faust
DESCRIPTION:This paper presents a new compiler called Poing Impératif.\nPoing Impératif extends Faust with imperative and object oriented features.\n\nImperative and object oriented features make it easier to start using Faust without having to immediately start thinking in fully functional terms. Furthermore\, imperative and object oriented features may enable semi-automatic translation of imperative and object oriented code to Faust.\n\nPerformance seems equal to pure Faust code if using one of Faust's own delay operators instead of the array functionality provided by Poing Impératif.

SUMMARY:LAC2011 - Compiling Signal Processing Code embedded in Haskell via LLVM
DESCRIPTION:We discuss a programming language for real-time audio signal processing\nthat is embedded in the functional language Haskell\nand uses the Low-Level Virtual Machine as back-end.\nWith that framework we can code with the comfort and type safety of Haskell\nwhile achieving maximum efficiency of fast inner loops and full vectorisation.\nThis way Haskell becomes a valuable alternative\nto special purpose signal processing languages.

SUMMARY:LAC2011 - Configuring your system for low-latency real-time audio processing
DESCRIPTION:Just installing GNU/Linux and a real-time kernel doesn't turn your system in a real-time low latency environment at once. A properly configured system demands some more modifications to what most distributions set up by default. And in a lot of cases a real-time kernel isn't even necessary. So besides going through some of the most important ways to improve the performance of your system this workshop may also debunk some tenacious myths.

SUMMARY:LAC2011 - Transmittance
DESCRIPTION:Transmittance explores artistic and scientific collaboration which is local\, global\, networked and broadcasted. It aims to research performative possibilities of streaming\, broadcasting and telepresence forging new types of performance and audience with focus on critical and socially aware artistic languages.\n\nA Transmittance context: Free streaming technology and telepresence software opened a possibility for new affordable spaces for performance. In late capitalism we are bombarded with images of body. We are manipulated with the notions of freedom and pleasure through the visual. It's an environment that increasingly segregates people by way of ethically questionable free market logic principles. Free software and open standards encourage innovation\, cooperation and solidarity in developed and developing world.\n\nProcessing of the audio/visual and the corporeal on a stage is an important strategy to subvert the numbing and blinding effects of contemporary life. Let's invent our own ways how to position our perceptions of self in relation to freedom\, pleasure and society of (promised) wealth. Let's open new spaces of visibility for performance and new media art. We need to actively bypass power structures that have a hold on physical spaces of artistic representation. Let's forge connections to new online audiences and collide different specifics of various artistic media.

SUMMARY:LAC2011 - PulseAudio on Mac OS X
DESCRIPTION:PulseAudio is becoming the standard audio environment on many Linux dektops nowadays. As it offers network transparency as well as other interesting features OS X won't offer its users natively\, it's time to have a closer look on possibilities on how to port this piece of software over to yet another platform.\n\nIn the recent months\, I put some effort into attempts to port PulseAudio to Mac OS X\, aiming for cross-platform interoperability between heterogen audio host networks and enabling other features PulseAudio offers such as uPnP/AV streaming.\n\nThis paper will first give a short overview about how CoreAudio\, the native audio system on Mac OS X\, is structured\, the various ways that can be used to plug into this system\, and then focus on the steps it takes to port PulseAudio to Mac OS X.

SUMMARY:LAC2011 - A position sensing midi drum interface
DESCRIPTION:This paper describes my attempts at making a cheap\, playable\, midi drum interface which is capable of detecting not only the time and velocity of a strike\, but also its location on the playing surface\, so that the sound can be modulated accordingly. The design I settled on uses an aluminium sheet as the playing surface\, with piezo sensors in each corner to detect the position and velocity of each strike. I also discuss the electronics (arduino based)\, the driver software\, and the synths I have written which use this interface.

SUMMARY:LAC2011 - Towards new mapping strategies for digital musical instruments
DESCRIPTION:This paper contends that the design of digital mu-sical instruments for live performance and compo-sition has been hindered by the tendency to create novel applications which fail to offer musicians access to the more perceptually-significant aspects of electronic music. \nTherefore\, as a means of addressing this problem\, this paper promotes the establishment of a more intelligent approach to the construction of digital musical instruments: one that is informed by relevant studies in human-computer interaction\, cognitive psychology and product design.

SUMMARY:LAC2011 - An LLVM bitcode interface between Pure and Faust
DESCRIPTION:This paper discusses the new LLVM bitcode interface between Faust and Pure which allows direct linkage of Pure code with Faust programs\, as well as inlining of Faust code in Pure scripts. The interface makes it much easier to integrate signal processing components written in Faust with the symbolic processing and metaprogramming capabilities provided by the Pure language. It also opens new possibilities to leverage Pure and its LLVM-based JIT (just-in-time) compiler as an interactive frontend for Faust programming.

SUMMARY:LAC2011 - An Interface for Realtime Music Using Interpreted Haskell
DESCRIPTION:Graphical sequencers have limits in their use as live performance tools. It is hypothesized that those limits can be ovecome through live coding or text-based interfaces. Using a general purpose programming language has advantages over that of a domain-specific language. However\, a barrier for a musician wanting to use a general purpose language for computer music has been the lack of high-level music-specific abstractions designed for realtime manipulation\, such as those for time. A library for Haskell was developed to give computer musicians a high-level interface for a heterogenous output enviroment.

SUMMARY:LAC2011 - A musician's workflow: composing\, recording and arranging with qtractor and friends
DESCRIPTION:The GNU/Linux audio environment is very much based on modularity as opposed to the monolithic approach on other platforms. As a result the GNU/Linux audio environment is very flexible and can be considered more an extension of an analogue set up with its intrinsic pros and cons. This is a totally different paradigm than used on other platforms so musicians coming from those other platforms can have a hard time adapting to the GNU/Linux modular approach. The aim of this workshop is to show by the use of a musician's workflow how you can benefit from the countless possibilities such a modular environment has to offer.

SUMMARY:LAC2011 - Web-enabled Audio-synthesis Development Environment (WADE)
DESCRIPTION:Collaboration and education in the world of digital audio synthesis has been facilitated in many ways by the internet and its World Wide Web. Numerous projects have endeavoured to progress beyond text-based applications to facilitate wider modes of collaborative activity such as\, network musical performance and composition.  When developing a software application one is faced with technology decisions which limit the scope for future development.  Similarly\, the choice of one audio synthesis language or engine over another can limit the potential user base of the application. This paper will describe how\, through the WADE system architecture it is possible to integrate existing software in a highly scalable and deployable way. The current incarnation of the WADE system\, as depicted in the WADE Examples section below\, uses the Csound synthesis engine and audio synthesis language as its audio server

SUMMARY:LAC2011 - Low-Latency Audio on Linux by Means of Real-Time Scheduling
DESCRIPTION:In this paper\, we propose to use resource reservations scheduling and feedback-based allocation techniques for the provisioning of proper timeliness guarantees to audio processing applications. This allows real-time audio tasks to meet the tight timing constraints characterizing them\, even if other interactive activities are present in the system. The JACK sound infrastructure has been modified\, leveraging the real-time scheduler present in the Adaptive Quality of Service Architecture (AQuoSA). The effectiveness of the proposed approach\, which does not require any modification to existing JACK clients\, is validated through extensive experiments under different load conditions.

SUMMARY:LAC2011 - Medusa - A Distributed Sound Environment
DESCRIPTION:Nowadays the use of computers to replace specialized (and expensive) audio equipment in studios\, live concerts and composing is a reality. This paper introduces Medusa\, a distributed sound environment that allows several machines connected in a local area network to share multiple streams of audio and MIDI\, and to replace hardware mixers and also specialized multi-channel audio cables by network communication. Medusa has no centralized servers: any computer in the local environment may act as a server of audio/MIDI streams\, and as client to remote audio/MIDI streams. We discuss the implementation of Medusa in terms of desirable features\, and report user experience with a group of composers from the University of São Paulo/Brazil.

SUMMARY:LAC2011 - Xth Sense: researching biological sounds of human body for an experimental paradigm of musical performance
DESCRIPTION:This paper seeks to outline methods underlying the development of the Xth Sense project\, an ongoing research which investigates exploratory applications of biophysical sound design for musical performance and responsive milieux. Firstly\, an exploratory study of the acoustics of body sounds\, namely muscle sounds is illustrated. I describe the development of an audio synthesis model for muscle sounds1 which offered a deeper understanding of the body sound matter and provided the ground for further experimentations in signal processing and composition. Then follows a description of the development and design of the Xth Sense - a wearable hardware sensor device for capturing biological body sounds\, this was implemented in the realization of Music for Flesh I - a first attempt at musical performance. Eventually I elaborate on the relations between the role of sound in cognitive experience and the acoustic capabilities of biologic body sounds and try to establish an array of principles which will provide the backbone of the next stage of my inquiry.
