Fracture Space is a musical instrument that creates clusters of large amounts of 3D audio objects in a 3D environment, each object individually equipped with psychoacoustic and physical attributes. The Fracture Space synthesis engine is based on systems of 3D sound objects that can be parameterized and stochastically distributed in a virtual acoustic environment. A very short fragment of an audio sample gets assigned to each of these objects. These signals are then recorded by virtual microphones and decoded for various speaker systems. The manipulation and control over the sound source properties are carried out via physically-inspired parameters in real-time.
