Head-related transfer functions used in binaural synthesis are usually measured with low directional resolution. Intermediate transfer functions are found by interpolation. In this study, measurements with a high directional resolution are used to determine the lowest resolution needed to interpolate head-related transfer functions precisely. The measured and interpolated head-related transfer functions are compared in an objective analysis and a listening experiment.
