An audio signal processing device to enable accurate calculation of angles and displacements and to enable reduction of circuit scales includes a digital signal processing circuit ( 31 ) that performs virtual acoustic image localization processing such that an acoustic image is localized at an arbitrary position in the vicinity of the listener by reproducing, using headphones ( 2 ) or a plurality of speakers, output signals obtained by signal processing input audio signals, and is characterized in that analog detection signals from a sensor ( 1 ) that detects the state of action of the listener are input to the digital signal processing circuit ( 31 ) via an A/D converter ( 30 ), and the transmission characteristics of these audio signals are modified in realtime, according to values derived by processing the values of analog detection signals from the sensor ( 1 ) or by processing the analog detection signals.
