  • Publication number: 20170347216
    Abstract: Broadly speaking, the technology relates to using wave field synthesis theory to simulate one or more idealized virtual point sources in a multi-speaker system. The speaker transfer function of each speaker is modeled, and the values and directional gradient of the combined speaker transfer function at test points in a convexly-bounded listening region are compared to the desired values and directional gradient for the idealized transfer function of the idealized virtual point source(s) at the test points to determine filter coefficient sets for each filter. The determined filter coefficients are those which minimize the total difference between the values and directional gradient of the combined speaker transfer function and the values and directional gradient of the idealized transfer function of the idealized virtual point source across all the test points for a plurality of frequency bins.
