Head-related transfer function (HRTF) Þlters are used in virtual auditory displays for the binaural synthesis of the direction of a sound source over headphones. Once low-order HRTF Þlters are designed, the interpolation of these Þlters becomes an important is- sue for the synthesis of moving sound sources. An HRTF Þlter in- terpolation method based on the displacement of HRTF Þlter roots is proposed. It is possible to obtain a minimum-phase interpolated Þlter given that the original Þlters are also minimum-phase. The computational complexity of the method is the lower than that of the linear interpolation of magnitude responses.
