A measured head-related transfer function can be decomposed into a minimum phase, a linear phase and an all-pass component.The audibility of the all-pass component is tested in a three-alternative forced choice experiment.Results show that a pair of head-related transfei functions can be represented by its minimum phase components if the appropriate interaural time difference is applied.The interaural time difference is found as the interaural group delay difference at O Hz determined from the excess phase (linear phase and all-pass) components.
