Quasi Wave Field Synthesis: Efficient Driving Functions for Improved 2.5D Sound Field Reproduction

Document Thumbnail

Optimised driving functions for a rectangular array of loudspeakers are approximated with driving functions with similar form and cost to Wave Field Synthesis (WFS) functions, by using a linear combination of several pre- lters and a delay for each function. The accuracy of the resulting reproductions are compared with WFS reproductions. The aim is provide improved e cient source driving functions in horizontal reproduction.
