1. A multichannel audio signal processing method processed by a decoder, comprising:
generating an N-channel audio signal of N channels by down-mixing an M-channel audio signal of M channels in a format converter using playback environment or virtual layout, the number of M channels being greater than the number of N channels;
generating a stereo audio signal by performing binaural rendering of the N-channel audio signal in a binaural renderer; and
outputting the stereo audio signal,
wherein a plurality of objects are inputted to an object renderer through a first dynamic range control (DRC1).
