Abstract: Wave Field Synthesis enables the reproduction of complex auditory scenes and
moving sound sources.
Moving sound sources induce time-variant delay of source signals. To avoid severe distortions,
sophisticated delay interpolation techniques must be applied. The typically large numbers of
both virtual sources and loudspeakers in a WFS system result in a very high number of simultaneous
delay operations, thus being a most performance-critical aspect in a WFS rendering system.
In this article, we investigate suitable delay interpolation algorithms for WFS.
To overcome the prohibitive computational cost induced by high-quality algorithms, we propose a
computational structure that achieves a significant complexity reduction through a novel algorithm partitioning and efficient data reuse.
