Presented at the 11th International Conference on Auditory Display (ICAD2005)This paper presents a new rendering method of a moving sound with the Doppler effect. In the conventional rendering method of moving sound, Head Related Impulse Responses (HRIRs) are simply changed according to the sound position. However, the Doppler effect cannot be added to a sound using this method. When a sound object moves with high speed, the pitch of a sound object should be controlled by some other rendering method. In our method, each HRIR is divided into two components, such as an initial delay and a main wave form. The two initial delays of both right and left ears are respectively recalculated based on relative speeds and a propagation path. These resultant initial delays are used in rendering. Thereby, the Doppler effect can be added automatically to a sound merely by setting the sound position in this algorithm. Details of this algorithm are discussed in this paper
