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 13):
Audio decoder of  claim 12 ,\n wherein the first joint multichannel decoder is a parametric joint multichannel decoder and wherein the second joint multichannel decoder is a waveform-preserving joint multichannel decoder, wherein the first joint multichannel decoder is configured to operate based on a complex prediction, a parametric stereo operation, or a rotation operation, and wherein the second joint multichannel decoder is configured to apply a band-selective switch to mid/side or left/right stereo decoding algorithm.
