AB  - In this paper, we present an improved model for Interaural Time Difference (ITD) estimation in reverberant environments. The Phase Transform (PHAT) weighting function, used in generalized cross correlation is investigated here for application to Interaural Cross Correlation (IACC) measurements from binaural microphones. A binaural model is developed to accommodate the method and demonstrations of its implementation in a real reverberant room show improved ITD estimation over non-weighted IACC, when compared to subjective listening results.
