Pseudo quadraphony
Under Pseudoquadrofonie the seemingly plastic will play an original stereo recording understood. In the mid-1970s, sound engineers in the entertainment and music industry tried electronically to process a stereo recording in such a way that the sound was reproduced with a quadrophone-like effect, but without real quadroinformation. The two additional signals for the rear speakers are artificially generated as a quadro effect for stereophony in the front through separate filtering in the left and right rear room channels, transit time delay and artificial reverberation .
