Title: Patrick Wijnings: Innovator in Microphone Array Calibration

Introduction

Patrick Wijnings is a notable inventor based in Eindhoven, Netherlands. He has made significant contributions to the field of microphone array calibration, holding 2 patents that showcase his innovative approach to solving complex problems in audio technology.

Latest Patents

One of his latest patents focuses on the calibration of microphone arrays with an uncalibrated source. This invention provides a statistical (Bayesian) algorithm that can determine gain and phase differences of an entire array simultaneously, even when the gain and/or phase of the source is unknown. The algorithm operates under the condition of reasonable environmental noise during calibration. Specifically, it employs a Bayesian regression with a complex log-normal prior and complex normal likelihood. The inherent phase-wrapping ambiguity in this regression is resolved by exploiting the similarity of likelihood between a lattice point and its Euclidean Voronoi region.
