Immersive Audio and How to Achieve It

@waytoomuchstuff 

Great post, I think "suspension of disbelief" is spot on in terms of what people want from any audio system.

@brianlucey Wrote:

 There is no contest between stereo and atmos/spatial, they are parallel deliverables, so please leave me out of your agenda :) 

I agree! 😎

A really good, two channel home system can .reproduce a large, deep, detailed soundstage w/ great dynamics & sound better than most live venues.

I don’t disagree, but I don’t think I would ever confuse a recorded playback on any system for a live performance of am orchestra.

More speakers & electronics etc is just more, not necessarily better.

Yep, more speakers also means more ways to screw it up, but you can screw up a stereo too. I found that although the Dolby specs for speaker setup are meticulous they were still not right for my room. Their diagram has the MLP toward the back of the room, equidistant between front and back walls worked better for me. Here are dolby’s specs:

This model where the MLP is equidistant was night and day better for my room:

Floyd Toole uses an equidistant MLP as well, our systems are almost identical, we both chose book shelf speakers mounted high on the wall as height channels, we both use wide channels, center channels above and below the screen and VOG channel.

Immersive audio is NOT the same as immersive acoustic...

True dat, most receivers and processors use some type of DSP to help with the acoustics.

Immersiveness in PHYSICAL acoustic is created by passive material treatment and active mechanical control of the room...

Yep, I agree 100%.

In digital audio of home theater for music theater the main point is NOT PRESERVING the physical recorded experience of a specific non amplified musical instrument , which reflect the trade-off choices of the recording engineer IN A CLOSED ACOUSTIC SPACE , the main point with home theater music experience in is rrecreating the general atmosphere of AMPLIFIED instruments ...

This is where the room acoustics come into play. There is a blueray concert by Kraftwerk recorded in Atmos and 3D video. It is the most lifelike recording I have ever heard in my room when played at reference levels. I think because the amplified instruments are easier to reproduce (mainly synthesizers).

When I play back solo piano I like minimal use of height channels, more use of wide channels and room acoustics help recreate the sound of the hall or studio the piano was recorded in.
