Abstract Based on the spatial Fourier analysis, a statistical model of the individualized interaural time difference (ITD) is derived from the head-related transfer function database for a Chinese subject. The model reflects the spatial left--right symmetry and front--back asymmetry of ITD. Moreover, by using three anatomical parameters of head and pinna, the model is able to predict individualized ITD in the horizontal plane. Performance of the four subjects outside the database demonstrates that the mean of the total error is less than 20μs, while the lateral performance is inferior to that at other directions.
