Claim 0:
1. An audio encoder for encoding a multichannel signal, comprising:
a downmixer for downmixing the multichannel signal to acquire a downmix signal, wherein the downmixer is configured as an active downmixer or a passive downmixer;
a linear prediction domain core encoder for encoding the downmix signal, wherein the downmix signal comprises a low band and a high band, wherein the linear prediction domain core encoder is configured to apply a bandwidth extension processing for parametrically encoding the high band;
a filterbank for generating a spectral representation of the multichannel signal; and
a joint multichannel encoder configured to process the spectral representation comprising the low band and the high band of the multichannel signal to generate multichannel information.
