This paper introduces an adaptive binaural rendering algorithm that renders sound image into a desired location for user-interactive headphone listening. The proposed algorithm provides steady sound localization during the listener's head movement by minimizing both localization error and timbral degradation caused by filtering HRTF. It is achieved by direct-ambient separation of input channel signal and the corresponding HRTF filtering with desired reverberation to the listener's head position. By a set of experiments, it is shown that the proposed algorithm provides precise localization.
