摘要
文中提出一种在虚拟听觉空间中加入多普勒效应以提高模拟运动物体效果的方法。该方法通过对原始声源运动轨迹的分析，对声源信号进行多普勒调频，并根据耳间时间差对双耳信号进行调相。最后利用连续球面空间上的HRIR对双耳信号进行滤波处理。经过验证，该方法处理后的声源信号运动感觉强烈。它为实现虚拟听觉空间提供了一种有益的新方法。
This paper presents a novel approach to improve the fidelity of simulating the moving objects in virtual auditory space by adding Doppler effects. The sound signal is Doppler FM modulated based on the analysis of the moving track of the original source, and then phase modulated according to the interaural time difference. Finally the binaural sound signal is filtered by the HRIR on the continuous sphere space. After testing, this method can give vivid simulated moving source signals. It has provided a new instructive way for the realization of the virtual auditory space.[
