The capacity of storage means required for generating virtual reflected sounds of left and right channels is saved. An auditory head outside lateralization apparatus has auditory lateralization means 102, 103 for processing input audio signals of left and right channels to localize a sound field at any desired position assumed with the head of a person wearing a headphone as the reference, and calculating the audio signals generated from a virtual sound field, virtual reflected sound generation means 111 for calculating virtual reflected sounds in a virtual sound field space relative to left and right channels from the one-channel audio signal resulting from adding the input audio signals of left and right channels, and addition means 112 or adding the audio signals of the left and right channels output from the auditory lateralization means and the virtual reflected sound generation means and calculating the audio signal from any desired virtual sound field.
