Claim Text:
1. An audio signal processing device comprising: a generation unit configured to generate n (where n is a natural number equal to or greater than 2) virtual process audio signals by processing at least one input audio signal so as to localize the input audio signal at a virtual position; an output unit configured to output the n virtual process audio signals generated by the generation unit to n speakers as first output signals and to output the n virtual process audio signals generated by the generation unit to a subwoofer as second output signals; a high-pass filter configured to attenuate a component of a frequency band lower than a predetermined cutoff frequency of the first output signals; and a low-pass filter configured to have the same order as the high-pass filter and to attenuate a component of a frequency band greater than the predetermined cutoff frequency of the second output signals, wherein the output unit is configured to output the first output signals and the second output signals so as to have mutually opposite phases.
