Psychoacoustics, the Determining Factor in Stereo Disc Distortion
A detailed study has been made using professional recording facilities of the distortion remaining in stereo recordings following the correction of the tracking angle error. It was determined that even when the tracking angle error is reduced to zero, the distortion products remaining are, by established standards, unreasonably high. Listener tests conducted under carefully controlled conditions indicate that the ear and nervous system will effectively reject these remaining distortion products. The implications of these results are discussed.
