Tid'Zam is an ambient sound analysis system for outdoor environments. It is a component of the Tidmarsh Farms project which monitors the environmental evolution of an industrial cranberry farm during its ecological restoration of wetland. Tid'Zam analyzes the audio streams generated by the deployed microphones in the wild in order to detect the sonic events happening on the site, such as bird calls, insects, frogs, rain, storms, car noise, human voices, and more.
This system is used to cross-validate other sensors for weather monitoring to identify, geolocalize, and track present wildlife and bird specimens over time. It also controls the audio mixers in order to mute or change the gain on noisy microphones.
