Increased interest in virtual space reproduction for games and simulation program motivates many researches on Head-related Transfer Function (HRTF) for producing 3D sound. HRTF characteristics which differ for each individual need intensive individual HRTF measurement. HRTF interpolation can be done in time-domain or frequency-domain to reduce the need of large HRTF measurement. In this research, CIPIC HRTF Database was used and three HRTF interpolation techniques are discussed. Linear vertical technique came out as best performer according to mean square error with 7.7818%, Linear horizontal technique with 92.83423%, and bilinear technique with 88.5655%. Interpolations of HRTF can be implemented on DSP Board easily for reproducing 3D sound. Subjective tests using DSP Board also performed on 6 subjects resulting in 55.83% correct localization for linear vertical technique, and 52.5% for both linear horizontal and bilinear techniques
