Acoustic translation of quadraphonic signals for two- and four-speaker sound reproduction
 Each of quadraphonic signals is applied to a respective one of a plurality of binaural localization networks to deliver a pair of binaurally correlated output signals to a respective one of a plurality of crosstalk cancellation networks where the input signals are modified so as to eliminate acoustic crosstalk which might be perceived by a listener if the non-modified signals were directly used to produce sound waves. The output signals from each crosstalk cancellation network are a pair of crosstalk-free signals which are combined in adders with signals from the other crosstalk cancellation networks to deliver a plurality of localized output signals to loudspeakers. The localization networks are so adjusted to make the localized output signals to appear to originate from anywhere in front of a listener.
