Larynx microphones and different software

Frank Scherbaum from Berlin came to visit by invitation. We tried out larynx microphones in several workshops. How do they work? Could it be useful in the folk song lab project? The idea is to get recordings that don’t have any disturbing sound from others which means being able to identify who is singing what in a group of singer. And at what time! Also we had the opportunity to register the session with different software.
