Ambitools won the Faust Awards 2016!


The Faust Open Source Software Competition aims at promoting innovative high-quality free audio software developed with Faust, a functional programming language for realtime signal processing and sound synthesis. The competition is sponsored by GRAME, Centre National de Création Musicale

The Faust Award 2016 was attributed by an international committee composed of :

  • Jean-Louis Giavitto (IRCAM, Paris, France),
  • Albert Graef (Johannes Gutenberg U., Mainz, Germany),
  • Pierre Jouvelot (Ecole des Mines, Paris, France),
  • Victor Lazzarini (Maynooth U., Maynooth, Ireland),
  • Romain Michon (Stanford U., Palo Alto, USA)
  • Yann Orlarey (GRAME, Lyon, France),
  • Dave Phillips (musician, journalist, and educator, USA)
  • Laurent Pottier (U. Jean Monnet, Saint-Etienne, France),
  • Julius Smith (Stanford U., Palo Alto, USA)

to Ambitools, a set of tools for real-time 3D sound field synthesis using higher order ambisonics (HOA).

Ambitools is developed by Pierre Lecomte, a PhD candidate at Conservatoire National des Arts et Metiers and Sherbrooke University. The core of the sound processing is written in Faust. The tools contain HOA encoders, decoders, binaural-filters, HOA signals transformations, spherical VU-Meter, etc. and can be compiled in various plug-ins format under Windows, Mac OSX, and Linux.

The jury praised the quality and the usefulness of Ambitools: a really useful and technically advanced Faust app and an impressive technical achievement ! Check the demo.

“Séance d’Hypnose” at Centre Pompidou

For the “Soirées Sonore #5” at Centre Pompidou, Paris, I made  a collaboration with the french sound designer/composer Théo Radakovitch.

The idea was to spatialize  Théo’s piece “La Séance d’Hypnose” with Ambitools and a mobile Ambisonic playback system. Most of the piece was pre-spatialized and played back in loop while two monophonic tracks were left to spatialize as sound sources. Thus, while the listeners could seat and enjoy the piece, one of them could control the trajectories and spatialize two of the sources with a remote. See also here.

The event went on Thursday May 16th 2018 inside the work “Respirare l’Ombra” at Centre Pompidou. Here are some picture:


As well, a binaural version of the mix is available below:

1st International Faust Conference

Ambitools was presented with demonstrations at the 1st international Faust TheConference (IFC-18) in Mainz, Germany.

The conference aimed at “gathering developers and users of the Faust programming language to present current projects and discuss future directions for Faust and its community”.

In this context, I gave a talk on Ambitools. The video of the talk is visible here:

As well, I gave some demonstrations with my personnal Ambisonic playback system.


The German television and radio featured IFC and talked a bit about Ambitools, see here and here (both in German).

Thanks a lot to the IFC committee and the Faust community for this conference, and thanks to Maximilian Schönherr for the interview on the german national public radio.
