In sound system, sound images are rendered by multiple loudspeakers in front of listeners. The core of solution is to design crosstalk cancellation filter. Robustness of sound system is depended largely on Eigen-value Diffusion Coefficient (EDC) of filter and sensitive to EDC. Based on EDC and non-singularity of inversion filter, a modified inversion filter technique using diagonal loading method is proposed. The simulation results indicate that the new method is more robust over the conventional.
