This may interest audiophiles who are interest in 3D sound. This is still object based immersive experience but with more options.

Just like pencils stereo will exist forever. It is the simplest form of sound reproduction with reasonable realism. Maybe other surround formats will get replaced.

Also, I'm wondering about their idea of taking photos of the listener's ears and software making corrections using the photos.  Would that work well or is it more a gimmick?

 

Your pinna is as unique as your finger print. No two persons will the same pinna and therefore the frequency response perceived by you is different from another. The only way you could compensate the difference is by eq’ing to modify the frequencies. Sony”s approach is valid.

I took that to mean that you can play it with just a smart phone, but you need the special headphones.

 

You still need a filter to adjust the frequency response of your pinna. You only need to measure once.

But the Sony app would do all that, right?  Analyze the photo, construct and apply the correction.  I would think that the correction would be more than just adjusting frequency response; it would also be some kind of balancing of the channels.

 

I suppose so. I think the main purpose of MPEG-H is for multichannel streaming. I  am still unsure how they are going to solve the internalization effect with headphones.
