摘要： Provided is an apparatus and method for converting a 10.2 channel signal into a multi-channel signal having a relatively few number of channels, thereby encoding and decoding the 10.2 channel signal. An apparatus for encoding/decoding a multi-channel signal may include a multi-channel signal converter to convert a first multi-channel signal into a second multi-channel signal having a fewer number of channels when compared to the first multi-channel signal, a remaining signal generator to generate a remaining signal using a difference between the first multi-channel signal and the second multi-channel signal, and an encoder to encode the second multi-channel signal and the remaining signal.
