This paper is a review on acoustic beamforming for noise source localization and its
applications. The main concepts of beamforming, starting from the very basics and …

Microphone arrays and associated array processing techniques have been developed for a
wide range of applications over the past few decades. These applications include speech …

Speech enhancement and separation are core problems in audio signal processing, with
commercial applications in devices as diverse as mobile phones, conference call systems …

Spherical microphone arrays have been recently studied for spatial sound recording,
speech communication, and sound field analysis for room acoustics and noise control …

The topic of spherical microphone array signal processing has been gaining importance
since the publications of Meyer and Elko around 2002, and fuelled by many others since …

This work demonstrates a comprehensive methodology for capture, analysis, manipulation,
and reproduction of spatial sound-radiation. As the challenge herein, acoustic events need …

Performance of microphone arrays at the high-frequency range is typically limited by
aliasing, which is a result of the spatial sampling process. This paper presents analysis of …

This paper studies the problem of frequency-invariant beamforming with concentric circular
microphone arrays (CCMAs) and presents an approach to the design of frequency-invariant …

Distant speech recognition (DSR) holds the promise of the most natural human computer
interface because it enables man-machine interactions through speech, without the …

An approach to optimal array pattern synthesis based on spherical harmonics is presented.
The array processing problem in the spherical harmonics domain is expressed with a matrix …
