摘要：
A residual signal decoding method including dividing a signal into a plurality of sub-bands in a frequency domain, wherein the signal is in a residual signal and is encoded with respect to an effective residual signal exceeding a masking curve that is generated with respect to a multi-channel audio signal, transforming the frequency domain into a time domain, and restoring the signal as an effective residual signal by synthesizing signals of the domain-transformed sub-bands.
