Abstract (en)

[origin: WO0162045A1] The invention concerns multi-channel reproduction of sound signals, more specifically derivation of a number of output sound signals from a pair of stereophonic signals such that each of these output signals can be reproduced via loudspeakers placed at the position of those phantom sources that would have been created by said stereophonic signals if they were provided to a pair of loudspeakers in a normal stereophonic set-up. The object of the invention is thus to replace said phantom sources by real physical sound sources, which would make the listening position in a room less critical as in a normal stereophonic set-up.
