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.
