Abstract

A signal translator includes right- and left-channel translating networks (11, 12), each being constructed to have a transfer function 1 /(A + B), where A is the transfer function of a direct acoustic path between a right-channel sound source and a listener's right ear and B is the transfer function of an acoustic crosstalk path between a left-channel sound source and the listener's right ear, the listener's head being positioned equidistant from the two sound sources. Through the right- and left-channel networks (11, 12), the right and left channel components of spatially correlated audio signals undergo transformation of 1/(A + B). When binaural signals are applied to the translating networks, the translated output signals are applied to a pair of loudspeakers in a listening room in which the acoustic direct and crosstalk paths transform the signals so that the impinging sound at the listener's ears is a distortion free audio signal. The input signals may be a pair of stereophonic signals, which after translation through the respective translating networks, are applied to a stereophonic headphone having a transfer function (A + B) to give the listener the same psychoacoustic effect as that obtained from the reproduction of the stereophonic signals with loudspeakers. <IMAGE>
