Claim 8:
9. The audio encoder according to claim 1,
wherein the linear prediction domain core encoder is configured to calculate the downmix signal as a parametric representation of a mid signal of an M/S multichannel audio signal;
wherein the multichannel residual coder is configured to calculate a side signal corresponding to the mid signal of the M/S multichannel audio signal, wherein the multichannel residual coder is configured to calculate a high band of the mid signal using simulating time domain bandwidth extension or wherein the multichannel residual coder is configured to predict the high band of the mid signal using finding a prediction information that minimizes a difference between a calculated side signal and a calculated full band mid signal from a previous frame.
