Abstract
A method of processing an audio signal is disclosed. The present invention includes receiving downmix information of at least one downmixed object signal, obtaining side information including object information, and mix information, generating plural channel information based on the side information and the mix information, and generating an output channel signal from the downmix information using the plural channel information, wherein the object information includes at least one of level information of the object signal, correlation information of the object signal, gain information of the object signal and supplementary information thereof.
