A spatial decoder unit ( 23 ) is arranged for transforming one or more audio channels (s; l, r) into a pair of bin-aural output channels (Ib, rb). The device comprises a parameter conversion unit ( 234 ) for converting the spatial parameters (sp) into binaural parameters (bp) containing binaural information. The device additionally comprises a spatial synthesis unit ( 232 ) for transforming the audio channels (L, R) into a pair of binaural signals (Lb, Rb) while using the binaural parameters (bp). The spatial synthesis unit ( 232 ) preferably operates in a transform domain, such as the QMF domain.
