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 12):
An apparatus for processing a multi-channel audio signal, the apparatus comprising:\n one or more processor configured to: identify a residual signal and N/2 channel downmix signals generated from N channel input signals; generate a first signal by applying the residual signal and N/2 channel downmix signals into a pre-decorrelator matrix; generate a second signal by applying the residual signal and N/2 channel downmix signals into the pre-decorrelator matrix, output a N channel output signal by applying the first signal and second signal into mix matrix, wherein the first signal is decorrelated based on N/2 decorrelators, and the second signal is not decorrelated based on the N/2 decorrelators.
