Day 2 - Friday, April/10 
Paper Presentation
10:00 Faust audio DSP language in the Web - Paper Presentation
(45 min)  Stephane Letz, Sarah Denoux, Yann Orlarey, Dominique Fober » Location: Main venue (P1)
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.
This 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.

Day 3 - Saturday, April/11 
Paper Presentation
14:45 MobileFaust: a Set of Tools to Make Musical Mobile Applications with the Faust Programming Language - Paper Presentation
(45 min)  Romain Michon, Julius Orion Smith III, Yann Orlarey » Location: Main venue (P1)
This work presents a series of tools to turn Faust code into various elements ranging from fully functional applications to multi-platform libraries for real time audio signal processing on iOS and Android. Technical details about their use and function are provided along with audio latency and performance comparisons, and examples of applications.

Day 3 - Saturday, April/11 
16:30 First Faust Open-Source Software Award - (misc event)
Video  Site  
(45 min)  Yann Orlarey » Location: Main venue (P1)
The Faust Open-Source Software Competition is intended to promote innovative high-quality free audio software developed with the Faust programming language. The winning software will receive a 2000€ price which will be awarded to the best submission by an international committee of leading experts in the field. The competition is sponsored by Grame, centre national de création musicale. The deadline for submissions is March 15, please check the linked website for details. The results of the competition will be presented in this session.

The schedule is a major guideline. There is no guarantee events will take place at the announced timeslot.
