Hello, longtime lurker here. Just caught a video I thought may be of interest to the readers of sound science.

In the video there is presented some simple explanation of the theory and application with some sound samples. What do you think? Were you impressed or was the effect not noticeable or innovative? I would love to hear some thoughts below!
Basically, what he's doing is combining binaural recordings (As old as the 1881 Théâtrophone) with speaker crosstalk cancellation (Carver Sonic Holography, Polk SDA, et al.) - both of which have been around for decades, and have been combined together for some time as well...

Although, I imagine this is a unique software solution. It's just that he's trying to pass it off like something no one has ever done before. You could probably try it yourself with your own speakers using binaural recordings and a Sonic Holography processor or preamp (Jeeze, I'm going to try that myself with mine when I get home)...
Also, this brings to my mind the question of in-ear versus near-ear binaural mics.
It would seem that near-ear microphones would be better for most applications - certainly speakers and circum/supra-aural headphones, so you don't go through an unnecessary extra pinnae transfer function that doesn't even match your own, while superimposing your own on it as well. You could also potentially have your own pinnae's transfer function measured - in both frequency response and time distortion - and have the signal processed through it for IEMs, where in-ear mics would otherwise seem to have the advantage (although you'd still have the pinnae transfer function mismatch to some degree, depending on your own ears and the dummy head).
