Abstract:
Disclosed are a multi-channel audio signal processing method and a multi-channel audio signal processing apparatus. The multi-channel audio signal processing method may generate N channel output signals from N/2 channel downmix signals based on an N-N/2-N structure.

Claim (Index 9):
The method of  claim 1 , wherein a size of the first matrix is determined based on the number of downmix signal channels and the number of decorrelators to which the first matrix is to be applied, and\n an element of the first matrix is determined based on a Channel Level Difference (CLD) parameter or a Channel Prediction Coefficient (CPC) parameter.
