我们提出了一个用于沉浸式虚拟环境的空间化音频渲染系统。该系统经过优化，可以使用现成的音频硬件在多扬声器环境中呈现足够数量的动态移动声源。基于简化的基于物理的模型，我们实现了音频质量、空间精度和性能之间的良好权衡。令人信服的声学室模拟是通过集成专业音频和广播社区使用的标准硬件混响设备来完成的。我们详细阐述了音频渲染的重要设计原则以及实际实现问题。此外，我们还描述了将音频渲染管道集成到基于场景图形的虚拟现实工具包中。
We present a spatialized audio rendering system for the use in immersive virtual environments. The system is optimized for rendering a sufficient number of dynamically moving sound sources in multi-speaker environments using off-the-shelf audio hardware. Based on simplified physics-based models, we achieve a good trade-off between audio quality, spatial precision, and performance. Convincing acoustic room simulation is accomplished by integrating standard hardware reverberation devices as used in the professional audio and broadcast community. We elaborate on important design principles for audio rendering as well as on practical implementation issues. Moreover, we describe the integration of the audio rendering pipeline into a scene graph-based virtual reality toolkit.
