An apparatus and method of generating multi-channel audio signals includes a voice signal removal unit to generate a first signal by removing one or more components of a plurality of frequency bands corresponding to a voice frequency range from an input signal, a voice signal amplification unit to generate a second signal by calculating a sum of channel signals of the input signal and amplifying one or more components of the plurality of the frequency bands corresponding to the voice frequency range of the sum signal, a control filter to generate a third signal by compensating for a level of the first signal, and a multi-channel audio generation unit to generate a center-channel audio signal and a front-channel audio signal using the second, third, and fourth signals.
