Abstract

[Problem] To provide an audio signal processing device which is capable of during playback of a multi surround format audio signal as a two channel audio signal reproducing a sound quality and a sound field generated with speakers actually installed. [Solution] Provided is an audio signal processing device equipped with a signal processing unit whereby when a two channel audio signal to be acoustically played back by using two electroacoustic conversion means which are provided at positions near the ears of a listener is generated from a multi channel audio signal with more than two channels and is output virtual sound image localization positions which are assumed for the respective channels of the multi channel audio signal and are located on the circumference of a circle around the listener are changed on the circumference from their respective original positions.
