Provided is an adaptive remastering apparatus and method for a rear channel, which emphasizes only signals of the rear channel while maintaining signals of other channels of a multi-channel audio signal. According to the adaptive remastering apparatus and method for a rear channel, virtual rear left and right channel audio signals are generated by multiplying a predetermined gain by ambient signals extracted from front left and right channel audio signals and are combined with input rear left and right channel audio signals, thereby increasing powers of signals of the rear channel.
