A signal translator includes right- and left-channel translating networks, 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 ear and B is the transfer function of an acoustic crosstalk path between a left-channel sound source and the listener's ear. Through the right- and left-channel networks, 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 signals. 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.
