环绕声前方传声器混合形式临界连接研究(下)(续(上))

Research on critical linking of the frontal microphones combinations in surround recording(Part Ⅱ)(continued part Ⅰ)

本文以环绕声前方三声道混合拾音制式为模板,以超心形、锐心形、以及它们与心形指向传声器的组合形式为研究对象,通过计算与数据分析,确定了根据所需拾音范围来设置L-C-R系统参数的方法,并分别对L-C、R-C及L-R三个区域声像定位分布情况进行综合考察,验证了前方三声道混合形式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理论后续研究加以铺垫。

This article focus on data calculation and analysis based on the pattern of frontal supercardioid、hypercardioid、and combinations by each of them with cardioid microphones as a mixed 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.
