Use it as the opening bed for a city scene, keeping it underneath everything else from the first frame. Once the location is set, add the Running Sound Effect for footsteps crossing the street, then bring in your main dialogue or action on top.
O tym dźwięku
This is a 14-second recording of a busy road, with vehicles passing close by, engines droning and wheels moving over tarmac in a continuous city wash. There is no music or speech, just layered road noise that swells as vehicles draw near and settles as they move on. It feels busy, open and alive, instantly placing the listener beside a city street rather than in a quiet room.
