Abstract

For the purpose of a realistic rendering of moving sound with no noticeable discontinuity, binaural synthesis of the timevarying sound field is performed by updating a dense grid of head related transfer functions, HRTFs. Unless the differences in HRTFs are sufficiently small, a direct switching between them will cause an audible artifact that is heard as a click. To avoid this problem and ensure the availability of enough HRTFs, we have first reduced the HRTFs using PCA and then proposed a binaural impulse-response interpolation algorithm based on the solution for the rational minimal statespace interpolation problem. Compared with existing interpolation techniques, this method allowed very precise reconstruction of HRTFs in the horizontal plane and proved to have superior performance for a wide range of azimuths.
