Abstract :
In this paper, a novel 3-channel system is proposed for the elevated speaker projection, which improves the robust performance compared to normal 2-channel system. Based on the system robustness analysis, two kinds of modified inverse filters are further exploited to enhance the virtual sound image. The superiority of this virtual sound system is described in the simulation and subjective testing is also carried out.
