Holophon is a set of tools for the programming and real-time manipulation of sound trajectories across different speakers. There are two different software packages: HoloEdit and HoloSpat.

Holo-Edit: A graphical and algorithmic editor of sound trajectories. Holo-Edit makes it possible to draw and graphically edit trajectories across a complex sound system. It’s also possible to program those trajectories with different automatic functions.

Holo-Spat: A group of spatializers working in real-time on Max-MSP , allowing the user to spatialize several sound sources independently over an array of multiple speakers. The control of the source trajectories can be made automatically by either using .holo files (made with Holo-Edit), directly by Holo-Edit using OSC or directly by various means in Max-MSP.
