摘要： 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.

摘要： A surround signal processing system receives a surround signal and also a program of processing the surround signal. The received surround signal is decoded into multiple-channel signals according to the received program. The multiple-channel signals include a left surround signal and a right surround signal. The multiple-channel signals are converted into two-channel signals according to the received program. The two-channel signals are transmitted to a pair of loudspeakers respectively. During the conversion of the multiple-channel signals into the two-channel signals, the left surround signal and the right surround signal are subjected to filtering processes according to the received program so that the left surround signal and the right surround signal will be converted into filtering-resultant signals. The two-channel signals are generated on the basis of the filtering-resultant signals. The filtering processes are designed to localize sound images at rear positions symmetrical with respect to a listener when a rear loudspeaker is absent and only front loudspeakers are used.

摘要： A surround signal processor reproduces multi-channel audio signals with a pair of left and right rear surround signals via a pair of speakers arranged at front left and right positions roughly symmetrically with respect to a listener. The processor has a sound image localizer with convolvers each of whose filter coefficients Hl and Hr are set based on head transfer functions for each channel of the rear surround signals as follows: Hl=(SF-AK)/(S.sup.2 -A.sup.2), where S and A denote transfer functions from each speaker to each listener's ear on the same and the opposite sides of each speaker, respectively; F and K denote transfer functions from positions at which each sound image is required to be localized to each listener's ear on the same and the opposite sides of each speaker, respectively. The localizer adds an output of the filter with filter coefficient Hl for one channel to an output of the other-channel filter with filter coefficient Hr for the other channel and outputs the added outputs as filtered rear left and right surround signals. The left and right rear surround signals passed through the localizer are added to front left and right stereophonic signals to be localized at rear left and right positions roughly symmetrically with respect to the listener, respectively.

摘要： A multiplexing-resultant surround signal is decoded into multiple-channel signals including at least a first left-channel signal, a first right-channel signal, and a rear-channel signal. Samples of the rear-channel signal are thinned out to generate a thinning-resultant rear-channel signal. The thinning-resultant rear-channel signal is subjected to a given process to convert the thinning-resultant rear-channel signal into a left surround-related signal and a right surround-related signal. The given process is designed to localize sound images at rear positions with respect to a listener when a rear loudspeaker is absent and only front loudspeakers are used. A surround-effect-added left-channel signal is generated on the basis of the first left-channel signal and the left surround-related signal. A surround-effect-added right-channel signal is generated on the basis of the first right-channel signal and the right surround-related signal.
