Near-coincident pair - do you need open space between the mics?
« on: December 08, 2010, 10:18:38 PM »
So I'm going to be in a recording situation where I'm recording using a near-coincident cardioid pair, but they are going to be separated by my head. There's no way around this, so I was wondering if this would throw off the stereo imaging? Thanks

Generally speaking if they are tucked inside your ear canal, such that the natural reflections from you ear lobe come into play, that's a binaural recording, and it's been said many times that recordings like that sound great with headphones but not great on a big stereo.  I've never actually tried it, I'm just spouting urban legend.  I would say that is the extreme example of no open space.

I have some DSM-6 omni mics which hang off my glasses.  I've run them back by my ears, and I've run them forward a bit more, about even with my eyes.  I think they sound better when I move them forward near my eyes.  It sounds a little more open, and a little less muffled.  I suppose that would be the example of "a little open space".

Yeah I've made a lot of binaural recordings, but this time I'll be using cardioids at a 110 degree angle. As far as I know that wouldn't be considered a binaural recording.

I'd think you'd still get a good stereo image.  The fact that your head is in the middle may cause the center instruments to be a little less prominent than they would be without your head, but I bet your head wouldn't make a huge difference.

This is correct as a true binaural recording using omnidirectional microphones. Still, as others have mentioned, I don't think you will have a problem doing what you want.
