Method for improving performance of 3D audio system

Based on the robustness analysis of the two-channel crosstalk canceler, physical insight into a 3D audio system is given, and a novel method is suggested for obtaining the condition number of TF and extended to the three-channel system. The results show that, a third loudspeaker can offer considerable control margin to the crosstalk canceler, and one can improve the performance of the 3D audio system by arranging the position of sound sources.
