Cancellation of Crosstalk in Artificial Head Recordings, Reproduced Through Loudspeakers

Authors: Moller, H.

AES Convention 84 · Paper 2610 · March 1988

Abstract

Concerning directional aspects, good results are obtained with artificial head recording techniques. Unfortunately, the system is traditionally restried to reproduction through headphones, since reproduction through loudspeakers introduces detrimental crosstalk between channels. Different analog approaches have been made to 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 set-up. The crosstalk is effectively cancelled, and the good imaging properties of headphone reproduction are preserved. The effect is unexpectedly independent of head position, when only the distance to the speakers 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.
