Symbolic Control of Spatial Sound Synthesis: OMPrisma
Author: Marlon Schumacher
OMPrisma is a library for sound source spatialization and spatial sound synthesis in the computer-aided composition environment OpenMusic. In addition to the spatialization of pre-existing sound sources it permits the synthesis of sounds with complex spatial morphologies using processes developed in OpenMusic and in relation to other sound synthesis parameters and to the symbolic data of a compositional framework.
OMPrisma is implemented as multi-tier system separating authoring and description of spatial sound scenes (OpenMusic) from rendering (Csound) and decoding/diffusion (Multiplayer). This approach facilitates alternative realizations of the same spatial sound scene with different rendering techniques and loudspeaker arrangements.
