Title (EN) CALIBRATING MULTIPLE MICROPHONES
(FR) ÉTALONNAGE D’UNE PLURALITÉ DE MICROPHONES
Abstract: front page image
(EN)The specification and drawings present a new method, apparatus and software product for calibrating multiple microphones (e.g., a microphone array) to match their sensitivity using an ambient noise by creating and updating one or more calibration signal level difference histograms.
(FR)La présente invention et les dessins concernent un procédé, appareil et produit logiciel nouveaux pour l’étalonnage d’une pluralité de microphones (par exemple, un réseau de microphones) pour adapter leur sensibilité à l'aide du bruit ambiant par la création et la mise à jour d’un ou de plusieurs histogrammes de différence de niveau de signal d’étalonnage.
