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.
