本文首先从理论上分析了声级差型双通路立体声信号的声像位置扩展和界外重放方法,并且对重放中产生的声像深度增加效应作了解释。文中最后还证明了这种重放方式可以推广应用到AB型和假头型等双通路立体声信号的重放中。
In this paper, firstly the method of sound image position extension and extra-boundary playback of the sound-level difference two-channel stereo signal is analyzed theoretically and the effect of increasing the sound image depth during playback is explained. Finally, the paper also proves that this replay method can be widely applied to the playback of two-channel stereo signals such as AB type and dummy type.
