Method and system for recording and reproduction of binaural sound

The invention provides an apparatus for the reproduction of sound in a listening environment, the sound including a left channel and a right channel and each of the channels including a high frequency component and a low frequency component. The apparatus comprises: means for comparing the left and right channels and forming left and right comparison signals therefrom; at least one left loudspeaker means for reproducing the left channel and the left comparison signal; and at least one right loudspeaker means for reproducing the right channel and the right comparison signal; wherein the apparatus is operable to reproduce the first and second comparison signals by means of the loudspeaker means, and the left and right comparison signals are, or the apparatus is operable to reproduce the left and right comparison signals to be, substantially incoherent with respect to each other and at a low level relative to the left and right channels, to produce a binaural effect for a listener in the listening environment.
