Group 1 sounds most wide and with more room, but a bit more distant and less precise than group 2. Group 2 is a bit narrow and upfront. Group 1 could be omnis or wide cardioids at some 42cm to 60cm distance between the two, also because of the fuller bass response. Group 2 sounds like cardioids in XY, or a cardioid with fig 8 in MS.
I combined the two tracks and actually found it an improvement of the total tonal balance. To my taste the group 1 mics are a bit muffled, but the image is most wide, with a bit of a hole in the middle. The group 2 mics have the better basic sound, but the image is too upfront and narrow for my taste. There is a middle peak. Together they even out quite nicely, but the precision is a bit compromised then.
Thank you, so much, earcatcher, for your analysis.
I don't know how I missed it, before. After all, that's the kind of thing I was fishing for.
Let me also apologize profusely. I, obviously, did not explain sufficiently, how the samples were organized. All the "a's" are the same pair, in the same configuration. Same with all the "b's". So, two different pairs. Three samples for each pair are provided, just to provide a variety of musical and tonal characteristics.
So, I put two pairs on the same stand: "a" is a pair of omnis at 45cm. "b" is a pair of cards in ORTF. I chose three excerpts and clipped each of the three excerpts from each of the two stereo pairs.
I appreciate your observations because they are "mostly right" about the mics and patterns.
I'm still trying to train my ears. I thought I would be "safe" with the omnis at 45cm-- that is, I thought that would be close enough to avoid the "hole in the middle". I must study and learn.
I'll delay just a bit longer in identifying the mics, just because some of them are also in my other current thread soliciting comments on an acapella choir.
Thank you, again, for taking the time to listen and provide such a thoughtful response.
