ABSTRACT:
Provided are method and apparatus for encoding and decoding multi-channel signals composed of a plurality of channels using a similarity between frequency bands and a similarity between channels. multi-channel digital signals are encoded/decoded using a similarity between frequency bands and a similarity between channels such that the size of signals to be transmitted to a decoding apparatus from an encoding apparatus can be reduced while maintaining predetermined sound quality and high-frequency signals can be effectively encoded and decoded to provide stable and natural sound quality.
