An audio signal play device (100) according to the present invention comprises: an acquisition unit (1) which acquires an audio signal; and a virtual sound field generation unit (80) which carries out a signal process on the audio signal, and generates a first speaker group (51) first play signal whereby a sound is oriented in a first virtual acoustic image site and a second speaker group (52) second play signal whereby a sound is oriented in a second virtual acoustic image site which is approximately identical to the first virtual acoustic image site. The virtual sound field generation unit (80) generates the first play signal and the second play signal with respect to a first sound, which is oriented in a first site among the first virtual acoustic image site which is denoted by the first play signal, and a second sound, which is oriented in a site which is approximately identical to the first site which is denoted by the second play signal and which is approximately identical to the first sound, such that at least one of the phase and the sound pressure value differ in a listening site. |
