1. An audio signal processing method comprising: obtaining a first audio signal and a second audio signal which represent a sound field between a first position and a second position, the first audio signal including a sound localized closer to the first position than to the second position, the second audio signal including a sound localized closer to the second position than to the first position; extracting a first signal and a second signal, the first signal being a component of a sound included in the first audio signal and localized closer to the second position than to the first position, the second signal being a component of a sound included in the second audio signal and localized closer to the first position than to the second position; generating (i) a first output signal by subtracting the first signal from the first audio signal and adding the second signal to the first audio signal, and (ii) a second output signal by subtracting the second signal from the second audio signal and adding the first signal to the second audio signal; and outputting the first output signal and the second output signal.
