| No recirculation or no feedback gives a slapback or a bunch of slapbacks. That can sound good if you have enough taps.... convolution. Without recirculation you should get an 'inverse' or 'gate' effect - or an RT that is only as long as the memory you have with an abrupt and unnatural cutoff. Seen that here.
Although an interesting effect is the 'black hole' reverb - something like fifty or so allpasses in series, with the output at the end and no recirculation except the feedback paths in each allpass. It gives a very slow buildup, and an almost symmetrical tail. I call it an effect because it is just that. But perhaps taking some taps throughout can shape this to be a useful reverb. It's on an Eventide.
Speaking of inverse or gated reverbs, if you can't recirculate because of the desired sound - after all, a gated reverb is supposed to cut off - I guess what you'd have to do is unroll the loops (just use a straight multitap with lots of taps) to the length or 'gate time' that you wanted, and use the slope of the output taps to shape the envelope. |
