Done with my mic "corner" setup.
Since the acoustic panels affect the entire space, the effect of being inside vs outside the U-shaped setup is rather subtle: https://open.audio/library/tracks/110054/
In the room itself, I felt the difference on the voice more strongly than on the recording. You can mostly notice the more narrow spatiality of the inside sound, whereas the outside sound has a broader stereo image (obviously, due to more reflections), also it has stronger colourisation.
