| Résumé |
This report describes the results and reflections from my residency with Ircam’s Acoustic and Cognitive Spaces research team during the year 2012. Central aspects of investigation were: the use of spatial projection system as an extension of electro-acoustic instrument design, the perceptual spatial identity of a source, the creation of a single object/body by a complex of sources, the interaction between a spatial sound object and its real or virtual surrounding space, and the empirical study of the application of these spatial organizations. Resulting from the study is a theoretical model in which the perceptual relationship between spatial organization and timbral/ motivic content is defined, and integrated into ‘spatio- timbral’ objects. Several ‘instrumental’ approaches to working with Wave Field Synthesis (WFS) and Higher- Order Ambisonic (HOA) rendering systems are presented, and implemented in the étude Fluoresce, composed for the inauguration of the new WFS and HOA system in Ircam’s Espace de Projection. In conclusion, future developments for the artistic manipulation of sound and space are proposed. |
