Encoder, decoder, system and method employing a residual concept for parametric audio object coding

摘要

A decoder is provided. The decoder comprises a parametric decoding unit (110) 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 (110) 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 comprises a residual processing unit (120) 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 (120) is configured to modify said one or more of the first estimated audio object signals depending on one or more residual signals.
