From busy intersections to back streets, vibrant parks to rooftops, this library of 56 sounds is an indispensable toolkit to create the perfect atmospheres without being in the foreground. You will get 3 hours of elevated and underground spots, freeways, intersections, bridges, viaducts, parking lots, parks, streets of all sizes, rooftops, window views and the city rumble and hum at its best. There are varying levels of horns, sirens, vehicles pass-by, school backgrounds and so forth at different times of the day.
