Abstract
Disclosed herein are systems and techniques for microphone array calibration, as well as communication systems in which calibrated microphones can be used. The systems and techniques disclosed herein may provide both phase and magnitude calibration for microphone arrays, resulting in improved performance for beamforming and other applications. Further, various systems and methods are disclosed herein for local storage of calibration coefficients in the microphone array (e.g., at the time of manufacture and calibration). Further, various systems and methods disclosed herein may include central application of the calibration of a microphone array (e.g., in an edge processor at operation time) to replace uncalibrated microphone signals with calibrated microphone signals further down in the signal chain.
