Why Urban Explosions? Most of the explosions in films, games or trailers do not occur on the plain, they occur in urban environments, there are buildings around them that in a very specific way form the character of the explosion sound. A feature of our effects library is that it was recorded in a real urban environment, so you get super-realistic reverbs and tails instead of artificially crafted reverbs or post-production tails that don’t sound at all in urban environments. For completeness, we also recorded explosions outside the city.
