Extraction of 3D Information from Circular Array Measurements for Auralization with Wave Field Synthesis
The state of the art of wave field synthesis (WFS) systems is that they can reproduce sound sources and secondary (mirror image) sources with natural spaciousness in a horizontal plane, and thus perform satisf...
