I've read most of this thread, and I'm surprised that no one mentioned using binaural mics. When you use them, you just have to ask listeners/watchers to put on a decent pair of headphones to get a good 15% or so sense of what it's like to be in the room.
While a
Neumann KU 100 dummy head mic is probably the best way to go, I've had acceptable results with these
Sound Professionals binaural mics. They are over $8k less expensive, but for that cost savings, YOU must provide the "dummy head". LOL. The hardest part is sitting still and being quiet during the recording.
This mic is a condenser, so it requires power from the recorder. You can't just plug it into a smartphone. I use the
Zoom H4n Pro, which can provide the necessary power and does a reasonable job of recording the audio. When I'm sharing the recordings as videos, I usually just take a still photo so that I don't have to worry about holding the camera still while I'm also trying to sit still.
Here's an example, shot from an earlier incarnation of my room. I should make an updated one since just about everything has changed. Feel free to judge me as much as you want. LOL.
