Abstract
A method for acoustic beamforming filter generation may be provided. Applying eigen decomposition to generate a matrix of eigenvectors and a matrix of eigenvalues to solve a pseudoinverse of a matrix of transfer functions. Substituting any eigenvalues in the matrix of eigenvalues that are less than a value of a gain control parameter with the value of the gain control parameter to form a revised matrix of eigenvalues. A matrix of spatial filter coefficients to apply to a sound signal received at least at the first speaker and at the second speaker may be calculated based on the matrix of eigenvectors, the revised matrix of eigenvalues, and a matrix of desired frequency responses.
