I've always wonder how to create those dense reverbs that you often hear in big cities. The classic example are sirens, car honks, or train whistles really far away. Whenever I listen to recordings that have these distant sounds baked in, they always have a very distinct reverb. But I can't for the life of me recreate these verbs with artificial reverb (e.g. to make a dry car horn seem far away). I assume there are IRs for that, but has anybody ever tried recreating them with "conventional" reverb? What's the trick?
