Download EGOSOUND, an egocentric, interactive and real-time approach of sound space Developed in the context of virtual environments linked to artistic creation, Egosound was conceived to visualize multiphonic sound space in an egocentric way. Ambisonic algorithms and a graphic editor for trajectories are implemented. An example of artistic project with Egosound is exposed. Parts of the software engine of Egosound are now available for download as external objects for Pure Data and Max/Msp graphical programming environments.
