Abstract
An apparatus (300) for converting a first parametric spatial audio signal representing a first listening position or a first listening orientation in a spatial audio scene to a second parametric spatial audio signal (112, 114) representing a second listening position or a second listening orientation is described, the apparatus comprising: a spatial audio signal modification unit (301, 302) adapted to modify the first parametric spatial audio signal (212, 214) dependent on a change of the first listening position or the first listening orientation so as to obtain the second parametric spatial audio signal (212, 214), wherein the second listening position or the second listening orientation corresponds to the first listening position or the first listening orientation changed by the change.
