Quality and Performance Assessment of Wave Field Synthesis Reproducing Moving Sound Sources

Document Thumbnail

Reproduction of moving sound sources by Wave Field Synthesis (WFS) arises some specific problems that make static source approach ineffective. An algorithm for the reduction of artifacts and natural representation of the movement effect, based on the synthesis of two virtual sources moving together, has been proposed in a previous work by the same authors. In this paper, a practical implementation of the algorithm is presented and evaluated in terms of workload and subjective sound source localization. The influence of some processing parameters on the computational cost has been studied. The sound quality concerning true spatial reproduction is assessed through listening tests and a comparison with previous approaches is reported.
