US Patent 10887709 Aligned beam merger

A system configured to perform aligned beam merger (ABM) processing to combine multiple beamformed signals. The system may capture audio data and perform beamforming to generate beamformed audio signals corresponding to a plurality of directions. The system may apply an ABM algorithm to select a number of the beamformed audio signals, align the selected audio signals, and merge the selected audio signals to generate a distortionless output audio signal. The system may scale the selected audio signals based on relative magnitude and apply a complex correction factor to compensate for a phase error for each of the selected audio signals.
