Enhancing Object Audio Control within an Immersive Sound System

Real time control over sound source positioning and movement is a primary advantage of object-based sound systems over channel-based systems. This paper describes a controller, processing engine, and associated library that enhances this object control. Apart from graphic spatialization control, the controller allows, for each object, the selection of its rendering algorithm, distance-based level, high frequency attenuation, reverb parameters and speaker isolation or locking. OSC control within the controller enables further control options.
