Abstract

This paper presents a new HRTF (Head Related Transfer Function) interpolation technique for three-dimensional sound generation. The proposed approach is based on the determination of the optimal weights to be applied to the HRTF coefficients of neighboring positions in the wavelet domain in order to obtain the HRTF at a given point. The proposed method is compared to conventional interpolation methods through the error analysis of the HRTFs in the frequency and time domains. It is verified that the proposed method presents smaller interpolation errors for all HRIRs (Head Related Impulse Responses) of an available database.
