I have found a convo app that can process 96khz 24bit True stereo L + R impulses I have.
LAConvolver
It sounds better than my Altiverb and Space Designer for playback of the same impulses Why?.. because SD will not load 96khz files so i have to convert them, and it sounds meatier and retains the body better. It's a bit fiddly though.
It is also free.
