The Dynamic Beamformer

open access: yes, 2012
Beamforming is one of the most commonly used methods for estimating the active neural sources from the MEG or EEG sensor readings. The basic assumption in beamforming is that the sources are uncorrelated, which allows for estimating each source independent of the others.

On the selection of the number of beamformers in beamforming-based binaural reproduction

open access: yesEURASIP Journal on Audio, Speech, and Music Processing, 2022
AbstractIn recent years, spatial audio reproduction has been widely researched with many studies focusing on headphone-based spatial reproduction. A popular format for spatial audio is higher order Ambisonics (HOA), where a spherical microphone array is typically used to obtain the HOA signals. When a spherical array is not available, beamforming-based
