One possible concept for the system architecture that was evaluated in more detail was multi-beam networks employing Butler matrices arranged in a 3D fashion. Butler beams are linearly independent ...

Near-field beamforming divides the space directly in front of the microphone array into a 64x64x64 grid of 5cm voxels, and can locate a sound source in that 3d space.

The Holoplot X1 Matrix Array Sound System is a unique modular system that uses advanced beam-forming and other technology to deliver "previously inaccessible” audio performance to a variety of venues.

Using NumPy for array and matrix math in Python Many mathematical operations, especially in machine learning or data science, involve working with matrixes, or lists of numbers.
