Abstract: A method and apparatus for transmitting/receiving multi-channel audio signals is provided. The apparatus for transmitting multi-channel audio signals includes: a multi-channel audio down-mixer configured to receive a multi-channel audio signal and transform the multi-channel audio signal into a down-mixed audio signal and a supplementary signal; a super frame generator configured to generate a super frame including a plurality of supplementary signal frames; and a packetizer configured to packetize the super frame, wherein the super frame includes supplementary signal frame number information and supplementary signal frame length information of the supplementary signal frames included in the super frame.
