Good results are obtained with artificial-head recording techniques when the directional aspects are considered. Unfortunately the system is traditionally restricted to reproduction through headphones, since reproduction through loudspeakers introduces detrimental crosstalk between channels. Different analog approaches have been made to the cancellation of crosstalk. However, digital signal processing opens up new opportunities. A system has been constructed in which a digitally filtered combination of the two channels is fed to each loudspeaker in a traditional stereo setup. The crosstalk is effectively canceled while the good imaging properties of headphone reproduction are preserved. The effect is unexpectedly independent of head position as long as the distances to the loudspeakers are equal. The system is shown to work in an anechoic room, but it is not formally limited to this. For use in a normal living room, more computing power is needed.
