Comparison of Higher Order Ambisonics and Wave Field Synthesis with Respect to Spatial Discretization Artifacts in Time Domain

Geometrical acoustic simulation is time consuming and can only achieve fixed impulse responses. A new system to create binaural impulse responses, whose acoustical characteristics can be arbitrarily specified, is proposed. Psychologically important parameters such as reverberation time, clarity index and inter-aural cross-correlation can be independently and significantly controlled. The fundamental procedures to realize this system are described. Simulation experiments were conducted to verify the availability and effectiveness of the algorithm.
