I feel like the ear mike version. The consumption version needs to be priced as such. Creators can pay $5 $7k $15k even. A nice mic as I learned on gearspace is $7k and according to some professional creators not a big deal in terms of cost. It can tax deducted etc.Actually the way BACCH works you can have speakers in non symmetric locations and it will still be fine. It is not super specific like using sonic holography. The in ear mics allow the system to adjust for speaker position or the intro edition one just inputs measured the relative speaker locations or does it by ear. Don’t quote me please but I’m pretty sure Dr Choueri said he puts the speakers in a traditional configuration as it makes audiophiles happy. I also imagine that being in the optimal listen widow for each speaker helps(especially ESL’s).
I have actually used BACCH on an NAD VISO-1(if you know what that is you will laugh) while it did not create a true binaural experience the sound field was well defined several feet out from each side of the device. It sounded like a nice set of bookshelves with excellent imaging.
When the Jambox Bluetooth speaker was around it implemented a fixed version of BACCH which was called LIVE AUDIO and actually was pretty good especially considering the modest quality of the speaker.
Any of this may be wrong.
Imho both head tracking and ear mic calibration would do well to be priced reasonably to increase the take up.
Education versions with limited file capability for experimentation would be very nice. Such to get used to any workflows associated in creation activities.
Even for consumption instead of a trial perhaps a version that only works on certain files but should have representation from a variety of genres and recording techniques.
It’s one thing to do research but it’s another to help people understand the value of said research.
