Introduction 

 
The Center for Computer Aids for Industrial Productivity (CAIP Center) at Rutgers University-New Brunswick continues to conduct advanced research in the area of high quality sound capture as part of a larger interest in multimedia-related research. The current research has a particular focus on active and passive microphone arrays. Microphone arrays enable the capture of high quality audio waveforms from remote sound sources, under adverse acoustic conditions. In particular, arrays allow the tracking and recording of moving human talkers without requiring the use of a cumbersome tethered microphone. 

Recent advances in circuit technology have made digital signal processing systems capable of real-time processing of multiple audio channels practical to implement and readily available.  This has been combined with an ever-increasing demand in voice controlled applications that exhibit robust, environment independent performance.  Microphone array systems have many uses for sound capture and acoustic source location in applications such as cellular telephony, video-teleconferencing, and audio interfacing with PC systems.
