Building Faust with CMake
This paper describes the new Faust building system that is now based on CMake. This new building system preserves the previous Makefile approach as much as possible while offering far more flexibility and above all, a platform independent solution for compiling the various faust components. The paper gives practical information to address basic uses of the building system as well as for advanced and custom settings.

3D Printing and Physical Modeling of Musical Instruments: Casting the Net
Predicting the acoustics of objects from computational models is of interest to instrument designers who increasingly use Computer Assisted Design.

Predicting the acoustics of objects from computational models is of interest to instrument designers who increasingly use Computer Assisted Design. We examine techniques to carry out these estimates using a database of impulse responses from 3D printed models and a custom algorithm for mode interpolation within a geometrical matrix. Test geometries are organized as a function of their physical characteristics and placed into a multidimensional space/matrix whose boundaries are defined by the objects at each corner. Finite Element Analyses is integrated into the open-source CAD environment to provide estimates of material vibrations also compared to measurements on the fabricated counterparts. Finally, predicted parameters inform physical models for aural comparisons between fabricated targets and computational estimates. These hybrid methods are reliable for predicting early modes as they covary with changes in scale and shape in our test matrix.

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.

Dans cet environnement, bien que tous les objets de la partition aient une dimension temporelle, le temps reste fixe i.e. que la date (ou la durée) d'un objet ne change pas, sauf à réception d'un message qui ne peut être produit que de manière externe ou événementielle. INScore n'inclut donc pas de gestionnaire du temps au sens classique du terme. A l'origine, ce choix a été dicté par le fait que le système fut conçu pour des usages couplés avec des logiciels de production sonore (e.g. Max/MSP, Pure Data), qui ont des contraintes de temps-réel plus strictes que lénvironnement graphique d'INScore. Toutefois, la nécessité d'introduire un temps dynamique a progressivement émergé, conduisant à un modèle original, à la fois événementiel et continu. Cést ce modèle qui est présenté et ses propriétés dans lénvironnement d'INScore.

We showcase results through an example of an interactive piece by composer Pierre Boulez, Anthèmes 2 for violin and live electronics.

Signal Rate Inference for Multi-Dimensional Faust
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...

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.

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.

Representation of Musical Computer Processes
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.
