A Large-Scale, Intelligent Three-Dimensional Microphone-Array Sound-Capture System

这是布朗和罗格斯大学的一个联合项目，目的是建造一个大型麦克风阵列，以及用于波束形成的相关处理器。在电话会议系统、多媒体教育系统和大型会议中心中的应用包括测向、回声消除和说话人区分。麦克风组共享执行A/D转换和低级别处理的麦克风模块。麦克风模块通过高速串行网络(可能是光学网络)链接到多处理器信号处理系统，以进行更高级别的处理。由此产生的系统正在一个试验性的电话会议设施中进行评估。

This is a joint project between Brown and Rutgers to build a large microphone array with associated processors for beam forming. Applications are direction finding, echo cancellation, and speaker differentiation in telconference systems, multimedia educational systems, and large conference centers. Groups of microphones share microphone modules that perform A/D conversion and low-level processing. The microphone modules are linked over a high speed serial network (possibly optical) to a multiprocessors signal processing system for the higher level processing. The resulting system is being evaluated in an experimental teleconferencing facility.
