摘要
为了在扩声系统设计中应用多通路空间环绕声技术,提出了"6.1+1"八通路空间环绕扩声系统的设计模式,并对系统的扬声器布置方式、系统结构、信号馈给以及系统性能进行了讨论。与常规的独立增加效果声系统的做法相比,该设计模式的最大优点是将常规演出扩声与空间多通路环绕声重放融为一体,使得常规演出声信号与特殊效果声信号均可作空间环绕播放。与基于矢量幅度移动技术的多通路效果声扩声系统相比较,这里提出的系统具有更好的性能价格比,是一种更为实用的扩声系统。
In order to use multi-channel surround sound technology for audio performance system design,the concept of the ＂6.1＋1＂ eight channel spatial surround audio performance system design is proposed. The loudspeaker location of each channel, the functions and the structures of the system, and the signal routing are also discussed. Compared with the normal audio performance system, the audio performance sound signal and effect sound signal can be played back in spatial surround mode by new system. Compared with the audio system based on the VBAP multi-channel effect sound technology, the proposed system has higher cost performance and is more practical.
