Time-domain Beamforming using 3D-microphone arrays
Acoustic measurements inside any cavity are mostly conducted with a view number of microphones. By this means it is possible to gain information about frequencies, orders, sound pressures. However, a space selective analysis is nearly impossible and it is not feasible to find multiple sound sources position in space in a practical way. Traditional beam forming systems with planar microphone arr...
متن کاملMicrophone Arrays
Such techniques—known collectively as beamforming—have been the subject of intense interest in recent years within the acoustic array processing research community. Unfortunately, such techniques have been largely ignored in the mainstream automatic speech recognition field, although this may rapidly change given the recent release and widespread popularity of the Microsoft Kinect R © platform....
متن کاملBeamforming in the Time-domain using 3D-microphone arrays
Traditional beam forming systems with planar microphone arrays do not give comprehensive information about the sound sources inside a cavity such as car interior or an office room. Acoustic measurements inside any cavity are mostly conducted with a few number of microphones. By this means it is possible to gain information about frequencies, orders, sound pressures. However, a space selective a...
متن کاملMicrophone Arrays : A Tutorial
This report presents a tutorial of fundamental array processing and beamforming theory relevant to microphone array speech processing. A microphone array consists of multiple microphones placed at different spatial locations. Built upon a knowledge of sound propagation principles, the multiple inputs can be manipulated to enhance or attenuate signals emanating from particular directions. In thi...
متن کاملInformation Measures for Microphone Arrays
We propose a novel information-theoretic approach for evaluating microphone arrays that relies on the array physics and geometry rather than the underlying beamforming algorithm. The analogy between Multiple-Input-Multiple-Output (MIMO) wireless communication channel and the acoustic channel of microphone arrays is exploited to define information measures of microphone arrays, which provide upp...
