Abstract

An audio signal processor includes a harmonic signal generator to generate a harmonic signal that includes a signal generated by frequency scaling components of a target audio signal by a factor of k, a left audio signal generator to generate a left audio signal by convolving a head-related transfer function from a target localization position of the target audio signal to a left ear of a listener with the target audio signal, a right audio signal generator to generate a right audio signal by convolving a head-related transfer function from the target localization position to a right ear of the listener with the target audio signal, a left synthesizer to generate a left channel audio signal by synthesizing the left audio signal and the harmonic signal, and a right synthesizer to generate a right channel audio signal by synthesizing the right audio signal and the harmonic signal.
