估计三维空间中声音的到达方向通常通过对来自全向麦克风的固定阵列的一组信号进行广义时延处理来执行。这需要专门的多通道A/D硬件，并将麦克风仔细排列成阵列。这项工作的动机是希望只使用标准的双通道音频A/D硬件和便携式设备。为了估计持续声音的到达方向，通过将麦克风安装在一个或多个计算机控制的平移和倾斜单元上来使麦克风的位置可变。在本文中，我们描述了一个设备的信号处理和控制算法，两个全向麦克风在一个固定的基线和两个旋转自由度。实验结果与真实的数据报告与脉冲和语音的声音在未经处理的，通常混响的室内环境。
Estimating the direction of arrival of sound in three-dimensional space is typically performed by generalized time-delay processing on a set of signals from a fixed array of omnidirectional microphones. This requires specialized multichannel A/D hardware, and careful arrangement of the microphones into an array. This work is motivated by the desire to instead only use standard two-channel audio A/D hardware and portable equipment. To estimate direction of arrival of persistent sound, the position of the microphones is made variable by mounting them on one or more computer-controlled pan-and-tilt units. In this paper, we describe the signal processing and control algorithm of a device with two omnidirectional microphones on a fixed baseline and two rotational degrees of freedom. Experimental results with real data are reported with both impulsive and speech sounds in an untreated, normally reverberant indoor environment.
