    摘要: A signal processing method performed by an encoding apparatus that down-mixes first through n channel signals to a mono-signal, an encoding apparatus, a decoding apparatus, and a decoding method are provided. The signal processing method includes: generating a spatial parameter between a reference channel signal that is from among the first through n channel signals, and residual channel signals from among the first through n channel signals except for the reference channel signal; and encoding and transmitting the spatial parameter to a decoding apparatus, whereby a down-mixed mono-signal may be exactly restored to original channel input signals.
