Optimal source distribution system for virtual acoustic imaging.
When binaural sound signals are presented with loudspeakers, the system inversion involved gives rise to number of problems such as, for example, loss of dynamic range and a lack of robustness to small errors of control performance. These problems for such systems are investigated and this has resulted in the proposal of a new system, the Optimal Source Distribution ("OSD") system, which overcomes these problems by means of variable transducer span. A practical solution to realise a variable transducer span by discretisation is also described. Several examples of the "OSD" system are demonstrated which in practice produce a very robust system over the whole audible frequency range. The relationship to the "Stereo Dipole" system is also described.
