Abstract
An audio signal processing apparatus includes; a first correlation component separating unit configured to predict a first signal from a second signal in a predetermined period to generate a first correlation component signal and to separate the first non-correlation component signal from the first signal by using the first correlation component signal; a second correlation component separating unit configured to predict a second signal from the first signal in the predetermined period to generate a second correlation component signal and to separate the second non-correlation component signal from the second signal by using the second correlation component signal; a correlation component synthesizing unit configured to synthesize the first correlation component signal and the second correlation component signal to generate a synthesized correlation component signal; a first gain multiplying unit configured to multiply the synthesized correlation component signal by a gain to generate a correlation component signal; a first signal adding unit configured to add a correlation component signal and a first non-correlation component signal; and a second signal adding unit configured to add the correlation component signal and the second non-correlation component signal.
