SUMMARY:LAC2015 - Live 3D Sound Spatialization with 3Dj
DESCRIPTION:3Dj is a SuperCollider library for real-time interactive 3D sound spatialization. It arises from the need of a free\, multiplatform\, Linux-compatible framework for sound spatialization. 3Dj is implemented in a modular way. On the one hand\, the Scene Simulator provides convenience abstractions for handling sound objects in a virtual environment (physical modeling\, predefined motions\, visualization). These informations are sent through OSC to the Spatial Render\, which synthesizes the resulting audio. Rendering can be done in Higher Order Ambisonics (up to 3rd order)\, VBAP or HRTF. Communication is based on the SpatDIF protocol\, facilitating the use of alternative simulators/renders. SpatDIF recording and playback capabilities are also provided. 3Dj is implemented in SuperCollider\, and makes use of several free software audio projects (Ambisonics Toolkit\, AmbDec\, Jack).\n\nThe talk will be complemented with a demonstration of the software in the installation space.

SUMMARY:LAC2015 - Toolbox for acoustic scene creation and rendering (TASCAR): Render methods and research applications
DESCRIPTION:TASCAR is a toolbox for creation and rendering of dynamic acoustic scenes that allows direct user interaction and was developed for application in hearing aid research. This paper describes the simulation methods and shows two research applications in combination with motion tracking as an example. The first study investigated to what extent individual head movement strategies can be found in different listening tasks. The second study investigated the effect of presentation of dynamic acoustic cues on the postural stability of the listeners.

SUMMARY:LAC2015 - Postrum II: A Posture Aid for Trumpet Players
DESCRIPTION:While brass pedagogy has traditionally focussed on sound output\, the importance of bodily posture to both short-term performance and longer-term injury prevention is now widely recognized. Postrum II is a Linux-based system for trumpet players that performs real-time analysis of posture and uses a combination of visual and haptic feedback to try to correct any posture issues that are found. Issues underpinning the design of the system are discussed\, the transition from Mac OS X to Ubuntu detailed\, and some possibilities for future work suggested.

SUMMARY:LAC2015 - NixOS for Musicians
DESCRIPTION:Computer audio users and developers need a reliable system\, yet they also need to be able to explore new tools without compromising stability. Nix\, the package manager\, and NixOS\, the distribution\, provide exactly that:\n\n\n\nNixOS is a declarative system. This means you define your entire system in a single text file. When you deploy such a configuration\, it doesn't matter what the previous state was\; you get exactly what you defined.\n\n\n\n* No more re-installs\, no matter how wild you hack!! Don't worry about upgrading or changing your system\; if anything goes wrong you can boot into an older system.\n\n\n\n* Backup\, version and share the configuration of your entire system. This is also great for fault finding\, for example on IRC.\n\n\n\nNix is a purely functional language\; it treats packages like immutable values. This has the following advantages:\n\n\n\n* Package isolation: Each package is only aware of its own dependency tree\, so there is no danger of dependency hell. You can have multiple versions of libraries installed at once.\n\n\n\n* Snapshots: Export just the parts of the system (i.e. a set of binaries plus their configuration) that you need to work on a music project so you can return to that project again in years to come without having to recreate the whole system.\n\n\n\n* Collaboration: Share exactly the same tools with a collaborator so that you can work together without the risk of running into incompatibilities or corrupted files. Nix\, the package manager\, can even do this across distros.

SUMMARY:LAC2015 - Composing Game Soundtracks - Demonstration and Discussion
DESCRIPTION:This 100 minute workshop consists of two parts\, a demonstration followed by a moderated analysis and discussion. It will be shown how to produce a soundtrack for a ficitional computer game. The goal is to have realized piece of music at the end of the workshop. Typical phases of a production will be shown and elaborated. Only fully digital resources (synthesizer\, sample libraries) with a free license will be used. First for pedagogical reasons\, so the audience can follow and reproduce the steps at home\, and second as a challenge.\n\nThe second part will be analysis and discussion. The audience and the author can share their expectations\, experiences\, pros and contras of a linux based environment for game-soundtrack production. This discussion will be moderated and is intended to be post-processed by the author to get feedback and wishes back into the software and audio development scene.

SUMMARY:LAC2015 - Open Educational Resources: Remixing Manuals and Tutorials for Linux Audio
DESCRIPTION:When preparing to teach a course using free and open source music software\, it is important to be able to freely remix existing materials in an easy and flexible way. There are good Linux Audio manuals and tutorials available online\, but often one would like to reorder their chapters\, rewrite or update text and screenshots\, add new material\, and so on. Sometimes an existing online resource is potentially interesting\, but if it is too outdated or unfit for a specific course plan\, a teacher may simply decide not to use it at all.\n\n\nIn this workshop\, I would like to open a discussion on current platforms (such as GitHub Pages and FLOSS manuals) available for writing and sharing educational materials. With hands-on demonstration on how to remix them\, I will illustrate the discussion with three recent projects I have worked on:\n\n\n1) A Gentle Introduction to SuperCollider\n\n2) Ardour 3 Beginner's Tutorial\n\n3) Open Music Theory

SUMMARY:LAC2015 - RTML: a Real-Time Machine Listening Framework
DESCRIPTION:Music Information Retrieval is a field with a strong potential for artistic and performative usages. However\, existing MIR tools are often interfaced by code\, thus limiting access to people without programming knowledge. We present RTML\, a graphical framework for Real-Time Machine Listening written in SuperCollider. RTML provides compact and simplified access to low- and mid level descriptors\, and convenient utilities to map descriptor outputs with external applications through OSC.\n\nThe talk also serves as a background for the author's "Listening Lights" performance at the Linux Sound Night.

SUMMARY:LAC2015 - Faust audio DSP language in the Web
DESCRIPTION:With the appearance of HTML5 and the Web Audio API\, a high-level JavaScript API for processing and synthesizing audio\, new interesting Web applications can now be developed. The Web Audio API offers a set of native and fast C++ audio nodes\, and a generic ScriptProcessor node\, allowing the developer to add his own specialized node in the form of pure JavaScript code. Several projects are developing abstractions on top of the Web Audio API to extend its capabilities\, and offer more complex unit generators\, DSP effects libraries\, or adapted syntax.\n\nThis paper brings another approach based on the use of the Faust audio DSP language to develop additional nodes to be used as basic audio DSP blocks in the Web Audio graph. Several methods have been explored: going from an experimental version that embeds the complete Faust native compilation chain (based on libfaust + LLVM) in the browser\, to more portable solutions using JavaScript or the much more efficient asm.js version. Embedding the Faust compiler itself as a pure JavaScript library (produced using Emscripten) will also be described. The advantages and issues of each approach will be discussed and some benchmarks will be given.

SUMMARY:LAC2015 - AVTK - the UI Toolkit behind OpenAV Software
DESCRIPTION:AVTK is a small lightweight user interface toolkit designed for building custom graphical user interfaces interfaces. It was conceived particularly to build LV2 plugin GUIs\, but is also usable for large and complex standalone programs. Focusing on user experience\, AVTK promotes ease of use for novices yet affords power-users the most efficient interactivity as possible. The author feels this is particularly important in live-performance software\, where user-experience and creativity are in close proximity.

SUMMARY:LAC2015 - Sound Synthesis with Periodic Linear Time-Varying Filters
DESCRIPTION:In this survey we explore implementations of recently proposed distortion synthesis techniques\, namely the Feedback Amplitude Modulation (1st and 2nd order cases) and Allpass filter coefficient modulation. These techniques are based on Periodic Linear Time-Varying systems\, in which we operate by finding a suitable modulation function to obtain a desired spectrum. In order to illustrate this survey and encourage exploration of these new techniques we present examples in the Csound language.

SUMMARY:LAC2015 - Ingen: A Meta-Modular Plugin Environment
DESCRIPTION:This paper introduces Ingen\, a polyphonic modular host for LV2 plugins that is itself an LV2 plugin. Ingen is a client/server system with strict separation between client(s) and the audio engine. This allows for many different configurations\, such as a monolithic JACK application\, a plugin in another host\, or a remote-controlled network service. Unlike systems which compile or export plugins\, Ingen itself runs in other hosts with all editing facilities available. This allows users to place a dynamic patching environment anywhere a host supports LV2 plugins. Graphs are natively saved in LV2 format\, so users can develop and share plugins with others\, without any programming skills.

SUMMARY:LAC2015 - Arch Linux as a lightweight audio platform
DESCRIPTION:This workshop discusses several purposes and reasons for chosing a rolling release distribution over a frequent release candidate one which translate very well into the field of pro-audio application:\n\n- Higher possibility for configurability\n\n- Software versions are up-to-date\n\n- Newer kernels guarantee (or at least raise the possibility for) better compatibility with hardware (old and new)\n\n- Easier to build own packages\, if not limited by outdated core components\n\n- Distribution documentation is up-to-date (less possibility for ambuigity)\n\n- Better chance for lightweight customization (if that's your thing)\n\n\nIn this tutorial I will elaborate further on the concepts and environments I chose to create concert- and installation-ready environments. This will include (but is not limited to):\n\n- Arch Linux package management (pacman and aura)\n\n- Arch Audio\n\n- Systemd\n\n- Awesome WM\n\n- Realtime kernels\n\n- Custom JACK2 startup scripts

SUMMARY:LAC2015 - Embedded Sound Synthesis
DESCRIPTION:This article introduces the use of the Intel Galileo development board as a platform for sound synthesis and processing\, in conjunction with the Csound sound and music computing system. The board includes an Arduino-compatible electronics interface\, and runs an embedded systems version of the Linux operating system. The paper describes the relevant hardware and software environment. It introduces a port of Csound\, which includes custom frontends that take some advantage of the board capabilities. As a case study\, a MIDI synthesizer is explored as one of the many potential applications of the system. Further possibilities of the technology for Ubiquitous Music are also discussed\, which use the various interfacing facilities present on the Galileo.\n\n\n\nThe demo video from the talk is available here: http://lac.linuxaudio.org/2015/download/embedded_movie.mov

SUMMARY:LAC2015 - Timing issues in desktop audio playback infrastructure
DESCRIPTION:In year 2008\, a feature with the name "timer-based scheduling" (also known as "glitch-free") has been introduced into PulseAudio in order to solve the conflicting requirements of low latency for VoIP applications and low amount of CPU time wasted for handling interrupts while playing music. The novel (at that time) idea was to use timer interrupts instead of sound card interrupts in order to overcome the limitation that the ALSA period size cannot be reconfigured dynamically. This idea turned out to hit some corner cases\, and workarounds had to be added to PulseAudio. Despite its age\, the implementation of the idea is still not 100% correct. This talk explains why it is the case and what can be done to improve the situation.

SUMMARY:LAC2015 - Low Delay Audio Streaming for a 3D Audio Recording System
DESCRIPTION:This paper presents a prototype of a 3D audio recording system which uses Wireless Acoustic Sensors to capture spatial audio. The sound is recorded in real-time by microphones embedded in each sensor device and streamed to a Processing Unit for 3D audio compression. One of the key problems in such systems is audio latency\, therefore this paper is focused on optimising the audio streaming time. Experimentation with the prototype system have shown that it is possible to achieve an end-to-end audio delay of 10ms and less using the Opus codec.

SUMMARY:LAC2015 - A Taste of Sound Reasoning
DESCRIPTION:We address the question of what software verification can do for the audio community by showcasing some preliminary design ideas and tools for a new framework dedicated to the formal reasoning about Faust programs. We use as a foundation one of the strongest current proof assistants\, namely Coq combined with Ssreflect. We illustrate the practical import of our approach via a use case\, namely the proof that the implementation of a simple low-pass filter written in the Faust audio programming language indeed meets one of its specification properties.\n\nThe paper thus serves three purposes: (1) to provide a gentle introduction to the use of formal tools to the audio community\, (2) to put forward programming and formal reasoning paradigms we think are well suited to the audio domain and (3) to illustrate this approach on a simple yet practical audio signal processing example\, a low-pass filter.

SUMMARY:LAC2015 - Xenakis: from analyses to performance strategies
DESCRIPTION:This poster provides a short analysis of Orient/Occident \, commissioned by UNESCO as music for a film by E. Fulchignoni\, which describes the development of civilizations: the cultural backgrounds are evoked by Xenakis through various timbres and specific rhythms: a wide range of unusual sound sources are used\, from the sound of a violin bow drawn over various objects to sounds from the ionosphere\, and excerpt from various Xenakis' works such as Pitoprakta\, Concret PH and Diamorphoses or from other GRM compositions.\n\nWe've studied the historical and technological context in which this work was conceived by using some historical sources.\nWe've underlined some specific ideas of this composition\, the composer's originality in Xenakis production and in the history of electroacoustic music.\nWe've investigated aspects of correspondence among the constituent sound materials\, illuminating the temporal relationships existing among them\, exploring sound identity correspondences and variations and providing a taxonomy of recurrent phenomena to help to rationalize compositional structuring processes. In this way we can point out the relationship between ministructure and macroform\, underlining the progressive aggregation process.\nThis objective has been achieved by means of: a) a Genetic Analysis based on the study of the composer's sketches b) a listening Analysis\, by following different musicological approaches.\nFor each technique we made some graphic representations and we coordinated them: we divided the work in sections\, characterized by a certain timbral and dynamic profiles homogeneity.\n\nWe've also studied the possible strategies for a live performance.

SUMMARY:LAC2015 - Auphonic: web-based automatic audio mixing and post production system
DESCRIPTION:Auphonic is a Linux-based web service to automate audio post production and mixing using a combination of music information retrieval\, machine learning and signal processing algorithms. Users upload their multi- or singletrack recordings and Auphonic will analyze the audio\, applies all processing automatically and keeps learning and adapting to new data every day!\n\nThe system includes an Adaptive Leveler\, which balances levels between speakers\, music and applies dynamic range compression\, Loudness Normalization to new broadcast standards (EBU R128\, ATSC A/85\, ...)\, a True Peak Limiter\, Automatic Ducking\, Noise Gate and Cross Talk Removal algorithms for multitrack recordings\, Automatic Noise and Hum Reduction and much more.\n\nFurthermore it can create multiple audio file formats with correct metadata and distribute all results to various destinations (FTP\, SFTP\, HTTP\, WebDAV\, YouTube\, SoundCloud\, Dropbox\, Google Drive\, S3\, Archive.org\, ...).\nThe algorithms can be used directly in the Web Interface\, with an API or in a separate desktop version.\n\nThe whole system is based on open source libraries and runs on a Linux system\, most of our algorithms are implemented in Python/numpy/C.\n\nWe have introduced a freemium model to finance auphonic.com\, which allows us to work on new algorithms every day.

SUMMARY:LAC2015 - Interactive virtual audio-visual concert simulation with TASCAR
DESCRIPTION:TASCAR is a toolbox for acoustic scene creation and rendering. In this demonstrator three concert stages can be interactively explored in a virtual audio-visual environment. On the first stage\, a time varying physical feedback model with three moving microphones and three simulated loudspeakers is placed. This simulation without any external sounds results in a sound experience very similar to Steve Reich's "pendulum music". On the second stage a jazz band is playing. The third musical event is a contemporary piece with moving virtual sources\, performed on a viola da gamba ensemble.\n\nThe interactive virtual acoustic environment is rendered in real-time and illustrates different aspects of the rendering software as well as the effect of binaural hearing. The simulation is rendered 3rd order horizontal Ambisonics. (A more extensive demonstration using an 8-channel loudspeaker setup takes place on Thursday in the installation space.)

SUMMARY:LAC2015 - MIDI Player Pro
DESCRIPTION:MidiPlayerPro\, MIDIPP\, is the engineers answer to playing a digital piano.\n\nPlaying a piano is a three dimensional problem. You need to know when to play a key\, how hard to press it and which key to hit. MIDIPP removes the last dimension leaving you as the musician with a two dimensional problem. In fact playing the piano becomes so easy you only need a single hand to perform the most common tasks an old-style musician will need two hands for.\n\nThe software allows you to play the piano in many new and exciting ways for your own and others pleasure. It can also be used to generate simple lyrics and chord handouts when playing in a band\, and has many tools for creating music and finding chords.\n\nMIDIPP is fully open-source and is available for Linux\, FreeBSD\, IOS and MACOS.
