Pseudostereophony
Pseudostereophony (also known as electronic stereo ) describes the seemingly plastic reproduction of an original mono recording . Sound engineers in the entertainment and music industries try electronically to process a mono sound recording in such a way that the sound is reproduced in a stereo-like manner . The disadvantage of not having any real stereo information remains unchanged.
history
In the early 1970s, many mono recordings were changed to pseudostereophonic. This was done through separate filtering in the left and right stereo channels and artificial reverberation or surround sound addition . This intervention was mostly irreversible. Since the original mono tapes were usually discarded after stereo-recording, some original mono recordings are irretrievably lost.
Reversible stereo-phonation
It is possible to make a pseudo-stereo recording from a mono recording without having to destroy the original mono signal. With mono playback, in which the signal is generated by superposition of the stereo channels, the original mono signal is output.
