Abstract:
A schematic block diagram of an audio encoder for encoding a multichannel audio signal is shown. The audio encoder includes a linear prediction domain encoder, a frequency domain encoder, and a controller for switching between the linear prediction domain encoder and the frequency domain encoder. The controller is configured such that a portion of the multichannel signal is represented either by an encoded frame of the linear prediction domain encoder or by an encoded frame of the frequency domain encoder. The linear prediction domain encoder includes a downmixer for downmixing the multichannel signal to obtain a downmixed signal. The linear prediction domain encoder further includes a linear prediction domain core encoder for encoding the downmix signal and furthermore, the linear prediction domain encoder includes a first joint multichannel encoder for generating first multichannel information from the multichannel signal.

Claim (Index 9):
Audio encoder of  claim 7 ,\n wherein the multichannel residual coder comprises: a joint multichannel decoder for generating a decoded multichannel signal using the first multichannel information and the encoded and decoded downmixed signal; and a difference processor for forming a difference between the decoded multichannel signal and the multichannel signal before downmixing to acquire the multichannel residual signal.
