It is an efficient way to eliminate “cross-talk” signals in spatial audio reproduction by using crosstalk cancellation system (CSS)，but CCS is quite sensitive to the listener’s head movement. A global optimal algorithm is proposed to provide increased robustness for the head movement，which adjusts the parameter based on the Minimax criterion. Simulation results demonstrate the new algorithm has better robustness of reproduction than that of traditional CCS algorithm for sweet point, especially in the low and middle frequencies where the speech energy mainly gathered .
