I'm in a situation in which I may have to add some reverb to a classical-music recording of a solo string instrument (I thought my two microphone set-up would work, but it didn't; I ended up with very good detail but very little of the room's considerable resonance and sonic depth). I imagine that's a bit of a sacred cow, in that I'm supposing that the difference between natural reverberance and electronically-generated reverberance is still pretty audible to a sensitive ear, in spite of whatever technological advances have occurred in recent years. Or am I wrong? Altiverb had been recommended to me, but it's extremely expensive and I'm not sure that when all is said and done I won't have traded one problem for another, i.e. an "unnatural" sound instead of the somewhat undesirable sound I had previously. Any thoughts and opinions would be welcomed. Thanks.
