An apparatus (100) for generating a plurality of parametric audio streams (125) (¸ i , ¨ i , W i ) from an input spatial audio signal (105) obtained from a recording in a recording space comprises a segmentor (110) and a generator (120). The segmentor (110) is configured for providing at least two input segmental audio signals (115) (W i , X i , Y i , Z i ) from the input spatial audio signal (105), wherein the at least two input segmental audio signals (115) (W i , X i , Y i , Z i ) are associated with corresponding segments (Seg i ) of the recording space. The generator (120) is configured for generating a parametric audio stream for each of the at least two input segmental audio signals (115) (W i , X i , Y i , Z i ) to obtain the plurality of parametric audio streams (125) (¸ i , ¨ i , W i ). |
