Improved sound separation using three loudspeakers
Jun Jie Yang, Woon‐Seng Gan, See-Ee Tan · Acoustics Research Letters Online · 2003
In a virtual sound imaging system, crosstalk cancellation filters are used to create an effective sweet spot for 3D sound reproduction via multiple loudspeakers.A new 3-channel system is proposed to improve system performance on sound separation.Based on the robustness analysis of a crosstalk canceller, a modified-inverse filter technique is explored and demonstrated using two different examples of symmetric speaker positions.The simulation results indicate that the present system is robust over a wider bandwidth compared to a conventional 2-channel system.
