So you think you're done with reverb plugins??? Think again!!! LOL!!!

I have some experience with this stuff (acoustic impulses) i.e. it's been around in Sound Forge (Sonic Foundry, SONY, now MAGIX) forever and the realism cannot be beat I'm afraid. I tried to look around for a free (but decent) IR loader for this stuff to post a link here but was not successful but I'm sure there must be one. I've got Voxengo's "Pristine Space" (https://www.voxengo.com/product/pspace/
) with all the other stuff that goes with it. There is a demo (not sure what the restrictions are). Voxengo's product allows for zero latency processing (which can be a problem with this type of effect unfortunately) (and this is not your sound card latency to which I'm referring either by the way).
Anyways. Just thought I'd throw this into the mix (no pun intended).
Probably a bit much for your average rock / metal mix i.e. I see it more for classical or sound effects really (could be wrong though). Fascinating stuff though.
