This paper focuses on consequences of artifact reduction in virtual sound source positioning method based on Differential HeadRelated Transfer Function (DHRTF). As resulted from previous experiments, spatial performance of this experimental method is very promising. However, under specific circumstances, artifacts may occur in the virtually positioned sound. Effective methods for artifact reduction were introduced before. This work discovers impact of the reducing algorithm in the time domain in order to understand phenomena occurring in the process. The cause of artifact presence results from narrow band peak(s) present in the DHRTF magnitude, which causes periodical character of the impulse response in the time domain.
