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 1):
A method of processing a multi-channel audio signal, the method comprising:\n identifying a residual signal and N/2 channel downmix signals; applying the residual signal and N/2 channel downmix signals into a pre-decorrelator matrix of a N\u2212N/2\u2212N structure defined based on bsTreeConfig; applying an output result of the pre-decorrelator matrix into mix matrix of the N\u2212N/2\u2212N structure; outputting a N channel output signal as an output result of the mix matrix, wherein the number of OTT box of the N\u2212N/2\u2212N structure is same as the number of a channel for the N/2 channel downmix signals.
