Steering Study of Linear Differential Microphone Arrays
IEEE/ACM Transactions on Audio Speech and Language Processing, 2021Differential microphone arrays (DMAs) can achieve high directivity and frequency-invariant spatial response with small apertures; they also have a great potential to be used in a wide spectrum of applications for high-fidelity sound acquisition. Although

Insights Into Frequency-Invariant Beamforming With Concentric Circular Microphone Arrays
IEEE/ACM Transactions on Audio Speech and Language Processing, 2018This paper studies the problem of frequency-invariant beamforming with concentric circular microphone arrays (CCMAs) and presents an approach to the design of frequency-invariant and symmetric beampatterns.

On the design of time-domain differential microphone arrays
Applied Acoustics, 2019Differential microphone arrays (DMAs) are characterized as compact superdirective beamformers whose beampatterns are almost frequency invariant. In this work, we present a time-domain design of Nth-order DMAs, which is important in some applications ...

Steerable Circular Differential Microphone Arrays
2018 26th European Signal Processing Conference (EUSIPCO), 2018An efficient continuous beam steering method, applicable to differential microphones of any order, has been recently developed. Given two identical reference beams, pointing in two different directions, the method allows to derive a beam of nearly constant shape continuously steerable between those two directions.

Remote microphone virtual sensing with nested microphone sub-arrays [PDF]
The Journal of the Acoustical Society of AmericaThis study uses the remote microphone technique to investigate the use of nested sub-arrays that incorporate either pressure or both pressure and pressure gradient information to estimate the pressure at remote locations in a random sound field. The sub-arrays of either pressure sensors or closely spaced microphone pairs are nested to form both uniform

IEEE Signal Processing Letters, 2023
This letter is dedicated to the design of fully steerable linear differential microphone arrays (LDMAs). We analyze the steerable ideal spatial responses and explain why conventional LDMAs consisting of only omnidirectional microphones have limited ...
