    • A surround signal processing apparatus, by which an inputted rear surround signal can be reproduced, together with two-channel front stereophonic signals, through a pair of speakers arranged in front of and in substantially right-and-left symmetry about a listener, in such a way that two sound images of the reproduced rear surround signal can be localized at two predetermined positions relative to the listener. The inputted rear surround signal is processed by a filter. The signal processed by the filter is added to one of the stereophonic signals, and then outputted to one of the pair of speakers. Further, an inversion signal of the filter-processed signal is added to the other of the stereophonic signals, and then outputted to the other of the speakers. Here, the transfer characteristics of the filter are determined as follows: (F-K)/(S-A), where S denotes transfer characteristics between one of the speakers and one of the listener's ears positioned on the same side as the speaker, respectively; A denotes transfer characteristics between one of the speakers and one of the listener's ears positioned on an opposite side to the speaker, respectively; F denotes transfer characteristics between one of the two positions at which two sound images are required to be localized and one of the listener's ears positioned on the same side as the image position, respectively; K denotes transfer characteristics between one of the two positions at which the two sound images are required to be localized and one of the listener's ears positioned on an opposite side to the image position; and / denotes a reverse convolution calculation.
    • 一种环绕声信号处理装置,通过这种环绕信号处理装置,可以通过一对扬声器连同双声道前置立体声信号一起再现一个输入的后环绕信号,该对扬声器以这样的方式围绕收听者排列在前面并且基本上左右对称 再现的后环绕信号的两个声像可以相对于收听者定位在两个预定位置的方式。 输入的后置环绕信号由滤波器处理。 由滤波器处理的信号被加到一个立体声信号中,然后输出到一对扬声器中的一个。 此外,滤波处理信号的反相信号被添加到另一个立体声信号中,然后被输出到另一个扬声器。 这里,滤波器的传送特性确定如下:(F-K)/(S-A)其中S表示扬声器之一和位于与扬声器相同侧的收听者的耳朵中的一个之间的传送特性; A表示扬声器之一和分别位于扬声器相对侧的收听者的耳朵之间的传送特性; F表示两个位置之间的两个位置之间的传送特性,在这两个位置之间需要两个声像被定位,并且一个收听者的耳朵分别位于与图像位置相同的一侧; K表示需要定位两个声像的两个位置之一和位于与图像位置相反的一侧的收听者的耳朵中的一个之间的传送特性; 和/表示反向卷积计算。
