tpM informed us he released 2 new work in progress videos of the Advanced Combat Sound Environment he is working on.
Quote tpM : I replaced the "old" slapback produced by nearby buildings to a more simple one as you can hear in the first video.
The second video is a short demonstration of how objects (in this case, a
house) affecting firing sounds in this soundmod. The shooter fires at a
car waiting next to the far side of the building (thats why you can
hear the metallic impacts). Work in Progress (not released yet).
