Binaural recordings of high-end immersive audio setups?

I watched some binaural recordings of some random things on YouTube and started wondering if it would be possible (or even a good idea) if someone here could do the same with their setup while playing a movie with a really good/immersive Atmos/DTS:X mix? Binaural recordings provide an excellent "sense" of where sounds are coming from (pretty much 3D-like) so it might give an idea of what it's like having a higher channel count setup (or maybe we could use it to compare some other attribute?). It should be noted that the "effect" of a binaural recording is better with headphones. However, I am not quite sure if those mics will work for this kind of purpose. Any thoughts/comments?

Perhaps but the Smyth Realiser does it very well.

Didn't know what that was and looked it up. It seems it plays back the actual movie in "virtual" immersive audio over headphones? But that wouldn't give you an idea of how someone's actual setup would sound, unless I am wrong.

It plays it through a filter that is calculated to recreate the output of your multichannel system (or someone else's) via your HRTF.

It does do a good job of emulating the acoustical characteristics of the loudspeakers and the room theyre in with a suprising realism even if just frequency response and room reflections. Maybe not the nuances though... like distortions of a tube amplifier, the impulse response of an electrostat, fpga controlled resistor ladder conversion, or an industrial isolation transformer and cryo treated wiring.

But it will externalize even a single channel and have you removing the headphones in disbelief.

There are a couple programs that provide similar performance where loudpseakers were measured with inear microphones. Out of Your Head provides pc users with access to several rooms made with a Realiser A8(so up to 7.1 only), though without personalized hrtf and no builtin headphone equalization. Another program in development is Impulcifer which is software only and requires a pc and a separate microphone purchase but will use your hetf speakers/room, and has measured headphone equalization as well

Mebbe that's why I liked it.

I would think to do something like this not on headphones but with loudspeakers, you would need an anechoic chamber devoid of reflections to properly render the DSP. And you're also going to have to compensate for crosstalk between the loudspeakers.
