#63 Spatial Sound Synthesis for Circular Membranes

Rudolf Rabenstein

Physical models of real or virtual instruments are usually only exploited for the generation of wave forms. However, models of two- and three-dimensional vibrating structures contain also information about the sound radiation into the free field. This contribution presents a model for a membrane from which the required driving functions for a multichannel loudspeaker array are derived. The resulting sound field reproduces not only the musical timbre of the sounding body but also its spatial radiation characteristics. It is suitable for real-time synthesis without pre-recorded or pre-synthesized source tracks.
