INScore is an environment for augmented interactive music score design, oriented towards unconventional uses of music notation, without excluding conventional approaches. In this environment, although all the objects of a score have a temporal dimension, the time remains fixed i.e., the date (or duration) of an object does not change, except when a message is received (sent from an external application or resulting from events handling). Thus, INScore does not include a time manager in the classic sense of the term. This choice was based on the fact that the system was originally designed to be used with sound production software (e.g., Max/MSP, Pure Data), that have more strict real-time constraints than INScore's graphical environment. However, the need to introduce dynamic time has gradually emerged, leading to an original model, both continuous and event based. The paper presents this model and its properties in the frame on INScore.

We present a completely re-organized set of signal processing libraries for the Faust programming language. They aim at providing a clearer classification of the different Faust DSP functions, as well as better documentation. After giving an overview of this new system, we provide technical details about its implementation. Finally, we evaluate it and give ideas for future directions.

This paper reports on the experimental native embedding of audio processing into the Antescofo system, to leverage timing precision both at the program and system level, to accommodate time-driven (audio processing) and event-driven (control) computations, and to preserve system behaviour on multiple hardware platforms. Here native embedding means that audio computations can be specified using dedicated DSLs (e.g., Faust) compiled on-the-fly and driven by the A... read_more

This paper reports on the experimental native embedding of audio processing into the Antescofo system, to leverage timing precision both at the program and system level, to accommodate time-driven (audio processing) and event-driven (control) computations, and to preserve system behaviour on multiple hardware platforms. Here native embedding means that audio computations can be specified using dedicated DSLs (e.g., Faust) compiled on-the-fly and driven by the Antescofo scheduler. We showcase results through an example of an interactive piece by composer Pierre Boulez, Anthèmes 2 for violin and live electronics.

We introduce a new signal-level, type-and rate-based semantic framework for describing a multi-rate version of the functional , domain-specific Faust language, dedicated to audio signal processing, and here extended to support array-valued samples. If Faust is usually viewed as a formalism for combining signal processors, which are expressions mapping input signals to output signals, we provide here the first formal, lower-level semantics for Faust based on sig... read_more

We introduce a new signal-level, type-and rate-based semantic framework for describing a multi-rate version of the functional , domain-specific Faust language, dedicated to audio signal processing, and here extended to support array-valued samples. If Faust is usually viewed as a formalism for combining signal processors, which are expressions mapping input signals to output signals, we provide here the first formal, lower-level semantics for Faust based on signals instead. In addition to its interest in understanding the inner workings of the Faust compiler, which uses symbolic evaluation of signal expressions, this approach turns out to be useful when introducing a language extension targeting multi-rate and multi-dimensional (array-valued) processing. More precisely, we provide (1) new syntax and dynamic semantics for (recursive) Faust-based signals, (2) a type and, more interestingly, rational rate static semantics and (3) a new rate inference algorithm, together with its soundness and (relative) completeness theorems. Preliminary experiments in a prototype implementation of this extension in the Faust compiler are underway.

INScore a été étendu pour fournir des opérations de composition de partitions en notation symbolique avec un jeu d’opérateurs qui de manière consistante, prennent des partitions en entrée pour produire une partition en sortie. L’API d’INScore inclut des score expressions, aussi bien au niveau OSC que dans son langage de script. Le travail présenté est basé sur une recherche précédente qui a porté sur les problèmes de consistance de la notation musicale à travers des opérations de composition de partitions. Ce sont les aspects langage et stratégies d’évaluation des score expressions qui sont abordés ici.

INScore is an environment for the design of augmented interactive music scores turned to non-conventional use of music notation. The environment allows arbitrary graphic resources to be used and composed for the music representation. It supports symbolic music notation, described us- ing Guido Music Notation or MusicXML formats. The environment has been extended to provided score level com- position using a set of operators that consistently take scores as arguments to compute new scores as output. INScore API supports now score expressions both at OSC and at scripting levels. The work is based on a previous research that solved the issues of the notation consistency across scores composition. This paper focuses on the language level and explains the different strategies to evaluate score expressions.

INScore is an environment for the design of Interactive Augmented Music Scores. This score provides a musical notation extension for arbitrary graphic objects, describing explicit relationships between graphic space and time, the representation of interpretation in music notation and real-time interaction. The porting to mobile platforms and the web allows an opening to new uses. These heterogeneous platforms raise both technical problems and questions of design, in terms of presentation as well as interaction with the score.

Music notation is facing new musical forms such as electronic and/or interactive music, live coding, hybridizations with dance, design, multimedia. It is also facing the migration of musical instruments to gestural and mobile platforms , which poses the question of new scores usages on devices that mostly lack the necessary graphic space to display the music in a traditional setting and approach. Music scores distributed and shared on the Internet start also to be the support of innovative musical practices, which raises other issues, notably regarding dynamic and collaborative music scores. This paper introduces some of the perspectives opened by the migration of music scores to mobile platforms and to the Internet and it presents the approach adopted with INScore, an environment for the design of augmented, interactive music scores.

The Web offers a great opportunity to share, deploy and use programs without installation difficulties. In this article we explore the idea of freely combining/composing real-time audio applications deployed on the Web using Faust audio DSP language.

With the advent of both HTML5 and the Web Audio API (a high-level JavaScript API for audio process- ing and synthesis) interesting audio applications can now be developed for the Web. The Web Audio API offers a set of fast predefined audio nodes as well as customizable ScriptProcessor node, allowing developers to add their own javascript audio processing 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. This paper brings an- other 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. Different 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 it- self 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.

The paper presents a study about the representation of musical computer processes within a music score. The idea is to provide performers with information that could be useful especially in the context of interactive music. The paper starts with a characterization of a musical computer process in order to define the values to be represented. Next it proposes an approach to time representation suitable to asynchronous processes representation.

We usually think of an audio application as a self-contained executable that will compute audio, allow user interface control, and render sound in a single process, on a unique machine.

We usually think of an audio application as a self-contained executable that will compute audio, allow user interface control, and render sound in a single process, on a unique machine. With the appearance of fast network and sophisticated, light and wireless control devices (such as tablets, smart-phones...) the three different parts (that are audio computation , interface control and sound rendering) can naturally be decoupled to run on different processes on a given machine , or even on different machines (on a LAN or WAN network). We describe a solution to run and control audio DSP on different machines based on: • the FAUST audio DSP language which permits local and remote dynamic compilation, code migration and deployment (using libfaust, libfaustremote and LLVM) • local and remote control capabilities (via OSC and HTTP based control interfaces) • JACK/NetJack network audio real-time layer to handle remote audio processing and rendering.

Ce moteur est facilement intégrable dans des applications qui nécessitent de jouer des fichiers son, des montages audio, et d'appliquer des effets et des traitements DSP en temps-réel. Une algèbre de description, de composition et de transformation des flux audio permet de construire des expressions complexes, que l'on va pouvoir ordonnancer à des dates précises dans le futur, et dont le rendu sera ensuite exécuté en temps réel le moment venu. L'application a un contrôle à l'échantillon près de ce qui est fait et à quelmoment, tout en étant déchargée des calculs audio temps réel proprement dit. Ce rapport donne une description formelle du langage d'expressions et des fonctionnalités de LibAudioStream.

L'intérêt pour ces applications est de disposer ainsi d'une chaîne de compilation complète, permettant de traduire les traitements synchrones, écrites en Faust, en code binaire exécutable fonctionnant donc à vitesse native. En s'appuyant sur la technologie LLVMcette chaîne de compilation est totalement autonome et ne dépend d'aucun outil de développement extérieur. Ceci facilite grandement le deploiement auprès d'utilisateurs non informaticiens. Elle est en outre très rapide, rendant ainsi dans de nombreux cas la phase de compilation transparente pour l'utilisateur. Le rapport présente la libraire libfaust, l'infrastructure de compilation LLVM, et trois applications de cette technologie : faustgen˜ un plugin Max/MSP permettant d'éditer, de compiler et d'exécuter du code Faust depuis Max, FaustNode, une extension de laWebAudio API permettant de compiler et d'exécuter du code Faust depuis un navigateur Web et faustcsound, un ensemble de quatre opcodes pour intégrer Faust dans le langage Csound.

This project introduces a recently developed prototype for real-time processing and control of complex piano notation through the pianist’s gesture. The tool materializes an embodied cognition-influenced paradigm of interaction of pianists with complex notation (embodied or corporeal navigation), drawing from latest developments in the computer music fields of musical representation (augmented and interactive musical scores via INScore) and of multimodal interaction (Gesture Follower). Gestural, video, audio and MIDI data are appropriately mapped on the musical score, turning it into a personalized, dynamic, multimodal tablature. This tablature may be used for efficient learning, performance and archiving, with potential applications in pedagogy, composition, improvisation and score following. The underlying metaphor for such a tool is that instrumentalists touch or cut through notational complexity using performative gestures, as much as they touch their own keyboards. Their action on the instrument forms integral part of their understanding, which can be represented as a gestural processing of the notation. Next to the already mentioned applications, new perspectives in piano performance of post-1945 complex notation and in musicology (‘performative turn’), as well as the emerging field of ‘embodied and extended cognition’, are indispensable for this project.

Par exemple, il est possible de glisser un nouveau fichier DSP sur une application FAUST en fonctionnement pour remplacer son comportement et ce, sans interruption du son. Il est aussi possible de transférer une application qui fonctionne en local, sur une autre machine, même si celle-ci utilise un système d\éxploitation différent.

INScore is an environment for the design of interactive music scores that includes an original event-based interaction system and a scripting language for associating arbitrary messages to these events. We extended the previous version by supporting scripting languages offering a great flexibility in the description of scores and in the interactions with scores. The textual format is directly derived from the OSC message format that was defined in the original INScore version. This article presents the scripting language and illustrates its ability to describe interactions based on events, while remaining in the temporal space. It also introduces the IRCAM gesture follower and how it is embedded into INScore to provide gestural interaction capabilities.
