Hello Fons, Thanks for writing. I have recordings made in highly reverberant spaces--and no such artifact exist in those recordings. Yes, a reverb tail can be heard, but not a loud, distinct, "gunshot" sound anywhere in the recordings. I will upload the 2 s IR for you (I can't go to ftp site from current coffee cafe at this moment). However, the same effect occurs with IRs downloaded from the Open Air Library--I tried them to see whether my recordings were to blame. My IRs were obtained using swept sine measurement and deconvolution, as per protocol outlined by Angelo Farina (by the way, did anyone ask if the Farina piezo-pinna transducer is related?). What might be the problem is the software used to apply the IRs to dry recordings. In my uploaded example, Sony Sound Forge 10d and its built-in Acoustic Mirror was used. Perhaps I should be using Altiverb, Waves IR3, YouVerb (I made this up), etc. I'm no expert on IRs--just getting started aside from apply Waves' and Trillium Lane's reverbs to music. Many thanks for help. Please listen to sample--it's more than a reverb tail--and pretty odd. Best always, Eric

Which you don't notice when the sound that caused it is included, as it sounds natural in that case. There may be another issue, but to determine this I'd need the 2 seconds B-format room IR you used. Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities.
