URB / Inaugurated in July, 2013, URB is a soundscape storage and analysis system idealized by José Alberto Gomes, and developed in partnership with Diogo Tudela. URB's goal is to keep record of the sonic profile of Porto, allowing researchers and artists to use that data set freely within their own projects.

Using Raspberry Pi computers located in four different places within the city, URB is constantly analyzing the city's soundscape and storing its sonic features in an on-line public database, which can be accessed at any time. Data is updated every five minutes with fresh values picked from Porto's streets.

URB XY / Still in its beta version, URB XY is a data visualization software designed by Diogo Tudela to grant fluid and intelligible navigation through URB's stored data.

Providing interactivity to URB's static and orthogonal tables, URB XY allows its users not only to explore the recorded material in its individuality, but also to grasp its overall contours as a whole.
