1. A multichannel audio signal processing method processed by a decoder, comprising:
generating an N-channel audio signal by down-mixing an M-channel audio signal in a format converter according to reproduction layout; and
outputting the N-channel audio signal,
wherein a plurality of channels corresponding to the M-channel audio signal are inputted to the format converter through a first dynamic range control (DRC1).
