Time Title Speaker(s)
A demonstration of the newest software updates from the Analysis/Synthesis team: IRCAM Lab TS (software with a simplified interface for transposition, time-stretching, and sinus noises and transients), the Snail Analyzer (frequency sound analyzer that uses an original chromatic alignment representation), and AudioSculpt (a presentation of the adaptive sonogram – AAAS). The team will also show the results of recent research on the analysis and synthesis of a singing voice:

  • a synthesis engine for singing based on text, the first version of the ANR project ChaNTeR
  • computer-aided audio and musicology technologies: analysis via voice to study popular music
  • conversion of a speaking voice to a singing voice
  • vocal improvisation with the real-time OMax improvisation system.

The conference attendees can test the software and ask questions concerning their specific domains of application.

11:00-11:30 Break
THE MAX MAESTRO is an animated notation system for choir/crowd of people, created within the artistic research project VOICES OF UMEÅ by composer Anders Lind at the department of Creative studies/ Umeå university/Sweden. By using simple animated graphics presented on a screen, instead of a complex notated score the idea was to:

1.Enable common people without score  reading skills to participate in complex performances  for choir/crowd of people

2.Enable a choir/crowd of common people to be synchronized with an electronic part in a performance without the need of a human conductor

3.Minimise the rehearsal time for a complex composition involving electronics and a crowd of common people performing live on stage

4.Enable live-improvisation with a choir/crowd of common people THE MAX MAESTRO was created within the graphic programming environment max/msp and runs as a stand alone application controlled by a midi device and an ipad.


Anders Lind (composer, Umeå university)
Cage is a library for the Max environment based entirely on the Bach library. It contains a large number of high-level modules for computer-aided composition (CAO). It was created thanks to the support of the Haute Ecole de Musique of Geneva. This library is made up of a group of tools for several categories of typical CAO problems: generating notes, generating and processing melodic profiles, symbolic processes inspired by processing the audio signal, harmonic and rhythmic interpolations, automats and L-systems, audio rendering, tools for set theory, tools for managing scores. The library has a pedagogical goal: the library’s modules are abstractions that can easily be analyzed and modified.

Special Session – Towards Smart Instruments:
16:00-16:30 Modalys News (ipad and PC/MAC) Robert Piechaud
SmartInstruments is a new team project on the conception of hybrid acoustic/electronic instruments. These high-quality instruments created in collaboration with renowned instrument-makers (Maurice Dupont guitar, Selmer bass clarinet, etc.) receive additional electro-acoustic components: sensors, switches, and electronic cards. The acoustic instrument becomes its own amplification system and radiates a sound made up of the original acoustic sound and the sound processed in real-time with electronic or digital means.
Adrien Mamou-Mani
Libellule, for hybrid bass clarinet, ensemble, and electronics is the fruit of a collaborative project with the clarinetist Alain Billard. This project was developed for the Selmer hybrid bass clarinet played by Alain; a prototype developed with the ANR IMAREV team at IRCAM. The instrumental sound is highlighted by the electronics that expand, transform, spatialized, and orchestrate each of the clarinet’s gestures in real-time. The system created allows for fine of control of the combinations of electro-acoustic timbres, their envelopes, and the parameters for sound signal processing. During the seminar, we will present the research carried out during this project, the implications, and the acoustic and instrumental consequences of this work with a hybrid clarinet. A selection of examples of the interaction between the hybrid clarinet and the electro-acoustic system will illustrate this conference, giving some ideas of where this research will lead in the future.
Marco Suarez and Alain Billard
Geecos, conceived in collaboration with the luthier Ludovic Barrier, are special wooden surfaces with different shapes and thickness, expressly designed to control real time sound synthesis.
Sounds produced on the surface by the performer’s hands are captured via a contact microphone and finely analysed in real time using sound descriptors: ircamdescriptors.
Data issued from sound analysis are used to finely modulate sound synthesis parameters in real time.
In this way the musician controls the inner details of sound synthesis through the sound of his own hands.
The synthesis engine uses modal synthesis in real time (Modalys) because it reacts to gestures in a physical and natural way. There is no sampled sound or sound playback.
The goal is to give the performer a control of sound similar to that of an acoustic instrument. In fact, the definition of timbre is based on the performer’s gestures and sensibility just like a violin. The challenge is to realize an electronic music where sound are just sound and not electronic sound.
Four Geecos have been designed to date, each one with its own name, shape and dimensions.
Every Geecos has a specific ergonomics to fit in multiple ways with the performer’s body and actions.
The quality of sound synthesis mostly depends from the sound produced on the surface of the instrument; Geecos are made of Val di Fiemme pinewood (Italy), the same used in most wooden musical instruments.
Geecos have been used for the first time in a large composition called “Voir-Toucher”, premiered on June 12th 2013 at Grande Salle of Centre Pompidou in Paris as a commission of Ircam

Sonogram analysis during composition frequently yields chord sequences with dynamic information. In this demo I wish to show ways in which the composer can shape musical objects derived from the spectra’s harmonic and dynamic evolution. These procedures transfigure the initial sound characteristics but remain closely linked to them. A particular emphasis will be given to using users drawings on the computer screen, but also to deriving morphological information from the sonogram itself. Importantly, it will be shown how to efficiently eliminate overlap between resulting notes and create voices (or polyphony) that can be orchestrated.
Gonçalo Gato (composer)
This presentation will show a range of public showings of the Inner Soundscape project. It will look at how the system was put in space and place and, depending on the event, taking on the form of a concert or an installation centered on sound synthesis work. The project uses varied modes of synthesis that, depending on the type of representation, focus on different arenas. The installation also uses the staging of sounds including it different systems that we could qualify as “Lo-Fi” placed among familiar objects. This presentation will talk about the journey from the IRCAM Live concert at the Gaîté lyrique in November 2013 that led to a sound installation produced in Athens during an archeological dig, passing first through the cloisters in the musée d’Art et d’Histoire de Saint-Denis. This presentation will focus on different systems of sound synthesis and the conditions of their use in the staging of the project.

InsectOS is an experimental video game that explores the use of music compositions as a narrative support for its levels.Each level begins with reproduction of a composition for keyboard that derives tempo from the characters speed and the playback instrument from type of surface the character is traversing.The demo is challenging to play for newbies given its elaborate control scheme, but a playthrough by an experienced player can result in a performance gratifying for spectators.
