ENHANCED METHOD FOR SIGNAL SHAPING IN MULTI-CHANNEL AUDIO RECONSTRUCTION

摘要

A reconstructed output channel, reconstructed with a multi-channel reconstructor using at least one downmix channel derived by downmixing a plurality of original channels and using a parameter representation including additional information on a temporal fine structure of an original channel can be generated using a generator (32) for generating a direct signal component (42) and a diffuse signal component (44) based on the downmix channel (38) is used. Only the direct signal component (42) is modified (34) such that the temporal (40) fine structure of the reconstructed output channel is fitting a desired temporal fine structure, indicated by the additional information on the temporal fine structure transmitted.
