Abstract:
Disclosed is an apparatus and method for processing a multichannel audio signal. A multichannel audio signal processing method may include: generating an N-channel audio signal of N channels by down-mixing an M-channel audio signal of M channels; and generating a stereo audio signal by performing binaural rendering of the N-channel audio signal.

Claim (Index 7):
A multichannel audio signal processing apparatus processed by a USAC 3D decoder, comprising:\n one or more processor configured to: downmix a M-channel audio signal of M channels in a format converter for generating N-channel audio signal of N channels based on a three-dimensional (3D) loudspeaker layout; and generate a stereo audio signal by performing binaural rendering of the downmixed N-channel audio signal in a binaural renderer; and output the stereo audio signal, wherein the USAC 3D decoder extracts a plurality of channel/prerendered objects, a plurality of objects from a bitstream, wherein the plurality of channel/prerendered objects are inputted to the format converter through first dynamic range control (DRC 1 ), wherein the plurality of objects are inputted to the object renderer through first dynamic range control (DRC 1 ), wherein the N-channel audio signal of N channels are outputted from the mixer, wherein the N-channel audio signal of N channels is inputted into the binaural renderer connected with the second dynamic range control (DRC 2 ) or is inputted into a third dynamic range control (DRC 3 ) with connected with the second dynamic range control (DRC 2 ) for a loudspeaker feed.
