BEAMFORMING TOOLKIT FOR LabVIEW
Beamforming and Direction Finding Toolkit is an add-on for LabVIEW that helps to apply standard beamforming algorithms to acquired or recorded data from sensors such as Microphone Arrays.
The toolkit provides an easy-to-use interface that requires the information about array geometry (coordinates of microphones) and recorded data in standard formats.
FEATURES & FUNCTIONALITY
The toolkit comes as a VIPM (VI Package Manager) installer which includes LabVIEW VIs for beamforming algorithms as well as examples demonstrating the usage of the toolkit - sound source simulation, beam shape 3D visualization and qualification for different beamforming algorithms, array geometries and incident signal frequencies, and sound intensity map generation (sound imaging).
For demonstration purposes, the examples incorporate acquired signal simulation for different array configurations which can be helpful for preliminary evaluation of the array for particular applications.
