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 10):
A apparatus of processing a multi-channel audio signal, the apparatus comprising:\n a processor configured to: identify N/2 channel downmix signals and N/2 channel residual signals; generate N channel output signals by inputting the N/2 channel downmix signals and the N/2 channel residual signals to N/2 one-to-two (OTT) boxes, wherein the N/2 OTT boxes are disposed in parallel without mutual connection, an OTT box to output a Low Frequency Enhancement (LFE) channel among the N/2 OTT boxes is configured to: (1) receive a downmix signal aside from a residual signal, (2) use a Channel Level Difference (CLD) parameter between the CLD parameter and an Inter channel Correlation/Coherence (ICC) parameter, and (3) not output a decorrelated signal through a decorrelator.
