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