摘　　要：以环绕声前方三声道时间差拾音制式为模板,通过计算与数据分析确定了根据所需拾音范围来确定L-C-R系统参数设置的方法,进而分别对L-C,R-C及L-R三个区域声像定位还原情况进行考察,验证了前方三声道时间差设置临界连接的可行性和L-C,R-C拾音区域平滑连接的稳定性,为Williams理论的后续研究加以铺垫。This article focus on data calculation and analysis based on the pattern of three frontal channels by time set in surround recording. After investigating the sound images given by the three regions of L - C, R - C and L - R , we verified the practicability and stabilization of the critical linking, which also provides the foundation of the Williams theory.

关 键 词：时间差拾音方式 拾音范围 声像定位 临界连接
