New System for Sound Spatialization

2012 is the year that marks the end of the installation of an ambitious sound spatialization system in IRCAM's Espace de projection.

This installation, made possible through funding from the Île-de-France region, the CNRS, and the UPMC, is made up of a ring of 264 loudspeakers placed at equal distances from each other around the stage and the audience for WFS (Wave Field Synthesis) sound reproduction and a dome of 75 loudspeakers for 3D ambisonic sound reproduction.

The WFS and ambisonic techniques rely on a physical formalism of the sound field and go beyond the limits of traditional sound spatialization systems. While traditional stereophonic techniques (stereo, 5.1) are a kind of trompe l’oeil and can only be truly appreciated from the center of the listening space, these new methods reproduce a sound field in which listeners can move freely while maintaining a coherent perception of the sound sources.

In scientific terms, this equipment represents both a research tool and subject for the analysis, synthesis, and perception of sound fields. We will illustrate the musical potential of these new methods of spatialization with recent creations made specifically for this system and adaptations of older works by artists such as Natasha Barrett, Jacob Druckman, Rama Gottfried, and Pierre Jodlowski.
