While OMPrisma 1.0 focused on compositional control of listener- or sweetspot-based spatialization techniques (such as VBAP or Ambisonics), OMPrisma 2.0 introduces new classes implementing spatialization techniques for non-centralized scenarios (such as DBAP, babo or ViMiC). This allows for reproduction setups with arbitrary loudspeakers placements, e.g. on stage, between listeners, for art installations contexts, etc.

The screenshot below, for example, shows a patch in which an OMPrisma class for Virtual Microphone Control (ViMiC) is used to simulate the spatialization technique employed in K.H. Stockhausen’s “Kontakte” (1959/1960); using a rotational table with a mounted directional speaker (sound source) and four stationary microphones placed around it. A detailed description of this technique can be found in: Braasch, J., Peters, N., and Valente, D. L. (2008). A loudspeaker-based projection technique for spatial music applications using Virtual Microphone Control. Computer Music Journal, 32(3):55 – 71.
