Use as is. It is already the response to an almost perfect delta-peak. If you really know the popping sound of your ballon, you could deconvolve that to get the response to a real delta-peak. But when you record two signals, one far away and one near the ballon/gun/wood-blocks and then use the nearer signal for deconvolution, you will probably also eliminate the early-reflections. Of course if its only the long tail you are after... Another note: When you do not cut the inital peak, you won't have to decide on the level of the IR compared to the dry signal. Because then your IR'ed signal is original (as it sounds through a popping balloon) and reflections. Have fun, Arnold
