Advanced methods of creating orthogonal signals |
摘要 |
A multi-channel signal having at least three channels can be reconstructed such, that the reconstructed channels are at least partly de-correlated from each other using a downmixed signal derived from an original multi-channel signal and a set of de-correlated signals provided by a de-correlator (101) that derives the set of de-correlated signals from the down-mix signal, wherein the de-correlated signals within the set of de-correlated signals are mutually mostly orthogonal to each other, i.e. an orthogonality relation between channel pairs is satisfied within an orthogonality tolerance range. |
