Abstract
A decoder is provided. The decoder includes a parametric decoding unit for generating a plurality of first estimated audio object signals by upmixing three or more downmix signals, wherein the three or more downmix signals encode a plurality of original audio object signals, wherein the parametric decoding unit is configured to upmix the three or more downmix signals depending on parametric side information indicating information on the plurality of original audio object signals. Moreover, the decoder includes a residual processing unit for generating a plurality of second estimated audio object signals by modifying one or more of the first estimated audio object signals, wherein the residual processing unit is configured to modify the one or more of the first estimated audio object signals depending on one or more residual signals.
