Right now I am trying grawk's microtrack -- still need to get a microphone/pair of microphones to go with it.
Yes, Gearslutz was the name I was looking for, thanks!
Yes, MicroTrack or H4 are high on my list.
Budget is a couple hundred US$. Might go up if I start doing this seriously, but that will happen later -- I need to see if, once I have the equipment, that I actually use it. Haven't decided between grawk's suggestion of Church Audio microphones or go straight to serious binaural microphones like Dallas Simpson uses. (I believe he uses DPA 4060's, which are a clone of something else, some well-known brand, and are very good.) But I'm thinking the latter is not a good idea with my allergies, as I make a lot of noise (straightening throat, coughing, sniffling, etc.), and he sticks them straight in his ears and walks around with them.
I don't necessarily need a one-button or built-in mic approach, but I need an all-encompassing approach -- I.E. everything needs to fit in one bag, so that I can remember to just grab that one bag. But yes, a one-button, built-in mic approach would definitely satisfy that criteria.
The cool sound was: they were doing some construction in the garage, and had left one of those large ventilation fans running. A piece of plastic tarp must have been waving near it, because a harmonic (7th, I think) of the fundamental of the fan was fading into and out of existence. I think it's the 7th for a very specific reason -- that's a particularly eerie harmonic to hear. It's utilized in one of the Prophet 5 patches with which I am familiar.
It was particularly musical. Sounded like something a musician would try to accomplish on purpose, and it was just there.
Or it might be the 7th harmonic of the 2nd harmonic (in other words, pretend the fundamental was really a divide-down subharmonic of the fundamental), since the fundamental was already pretty low.
