我们提出了使用视觉信息在交互式虚拟环境中获取和生成音频信息的新技术。这些技术不存在会妨碍用户的机制，例如夹式麦克风、耳机等。描述了从空间中给定位置提取声音和渲染听觉场景的方法，即给定用户位置，产生在用户看来来自 3D 空间中任意点的声音。在这两种情况下，有关用户位置的视觉信息都用于指导算法，从而解决了难以且通常无法稳健解决的问题。的
单独听觉域。
We present novel techniques for obtaining and producing audio information in an interactive virtual environment using vision information. These techniques are free of mechanisms that would encumber the user, such as clip-on microphones, headphones, etc. Methods are described for both extracting sound from a given position in space and for rendering an\auditory scene," i.e., given a user location, producing sounds that appear to the user to be coming from an arbitrary point in 3-D space. In both cases, vision information about user position is used to guide the algorithms, resulting in solutions to problems that are di�cult and often impossible to robustly solve in the
auditory domain alone.
