Reproduction of Moving Virtual Sound Sources with Special Attention to the Doppler Effect

In this paper, we outline a basic framework for the reproduction of the wave field of moving virtual sound sources. Conventional implementations usually reproduce moving virtual sources as a sequence of stationary positions. This process leads to various artifacts as reported in the literature. On the example of wave field synthesis, we show that the explicit consideration of the physical properties of the wave field of moving sources avoids these artifacts and allows for the accurate reproduction of the Doppler Effect. However, numerical simulations suggest that the artifacts inherent to the reproduction system can lead to a heavy degradation of the reproduction quality.
