Abstract:
A method and apparatus of effectively encoding and decoding a high-frequency signal of a multi-channel audio are provided. A multi-channel audio decoding apparatus may down-mix a multi-channel audio input signal, expand a number of channels of the down-mixed signal, select at least one of the expanded channel signal, extract a parameter indicating a characteristic relation between the selected signal and the multi-channel audio input signal, and encode the down-mixed signal and the extracted parameter.
