Simulation of Continuously of Moving Sound Sources in Reverberation Field

The simulation of continuously moving sound source is an important issue for virtual auditory display, but current research has mainly focused on the free-field horizontal plane. In this paper, an algorithm based on the combination of FFT block convolution overlapped add and cross fading technology is proposed to simulate the continuous moving sound source of the lateral vertical plane under different reverberation fields, and verify it through subjective listening and objective evaluation. The results show that the moving sound source has better continuity and smoothness in the reverberation field (0.4s, 0.8s and 1. 5s) compared to the free field; in addition, the free field and reverberation field both obtain high-Quality 3D sound source spatial quality.
