selection of sound installations will complement the concert programme, and will be presented in the studios and public spaces of IRCAM. Among other things, they will focus on real time interaction technologies and virtual reality devices, and will be presented by artists, teaching institutions, creation and research institutions, and by Forum members.

S0UNDB1TS is a sound installation project by Robin Minard and Norbert Schnell realized at IRCAM with the support of the Canada Council for the Arts. The project features sound installations with hundreds of independently driven sound transmitters controlled by a central processing unit.

Holophony is a new technology that aims at capturing and reproducing "sound holograms". Similarly to holograms, the goal is to record or create a sound scene in relief, i.e. with spatial information of distance and direction of the elements (sources) that compose it. Whereas conventional stereophonic techniques are similar to "trompe-l'œil" and can be experienced only at the center of the setup, holophony reproduces a true sound field independent on the listener position. Therefore, listener perception of the perspective remains coherent throughout the listening space. Discrimination between far sources, that are perceived everywhere at the same angular position (plane waves), and close sources, located at a precise spatial position even inside the listening area (in front of the panels), can be clearly produced. In this case, the listener can experience different perspectives while moving in the sound installation. It is also possible to create a single perspective throughout using only plane waves (sound sources at infinite distance), no matter where the listener is located. The reproduction of a given room acoustic can be achieved in the all listening area, helping to simulate a more plausible acoustics space. A user interface enables control of the sound scene (position of sound sources, parameters of the room effect). This demonstration uses a typical reproduction system of the CARROUSO project composed of 7 MAPs (Multi-Actuator Panel) corresponding to 56 channels.
The key objective of the project CARROUSO (Creating, Assessing and Rendering in Real-time Of high-quality aUdio-viSual envirOnments in MPEG-4 context) is to provide a new technology that enables the transfer of a sound field, generated at a certain real or virtual space, to another (usually remote) space. The content creator can chose whether to transmit a real sound scene using holophony at the recording or to modify it by choosing a different location for the sound sources or another room effect. At the receiving side, the user has the possibility to choose his listening position inside the sound scene (whether by physically moving inside the reproduction area or by modifying parameters). He is free to choose his view point like he would modify the "camera" position in virtual reality or interactive television applications.

This installation is a study on elementary geometric shapes, drawn in 2D on a board and realised in 3D with sounds. Réflexions will use a diffusion system which associated "le Cube" développed at Ircam and the "Audiospotlight" développed at MIT. The Cube is a virtual source with controlled directivity. The Audiospotlight is an ultrasound speaker emitting a sound beam similar to a projector.
