Abstract
Systems and methods for determining the location of a microphone by using sounds played from loudspeakers at known locations. Systems and methods may thereby require a minimal level of infrastructure, using sounds that would naturally be played in the environment. Systems and methods may thereby allow devices such as smart-phones, tablets, laptops or portable microphones to determine their location in indoor settings, where Global Positioning Satellite (GPS) systems may not work reliably.
