Reply to comment by PeaceFar9770 in LG Display’s ‘invisible’ speaker brings sound to any surface in your car by MicroSofty88
They already have this technology out there but im also curious to know specifically what LG can do with it. Just like Sony, these guys can work wonders with hardware

I think Sony has a system of speakers that do something similar, they're capable of making surround audio and you feel like there's Audio coming from behind even when there's no speaker behind you, it's kinda crazy.

They do they also have the ht-a9 system which you can place 4 speakers at any height and any spacing as long as they have a general 4 corner layout and they calculate how to make sound and they call it a virtual 12 speakers

I’ll have to dig into this, out of pure curiosity. “Hearing” a phantom center speaker is a real thing in music, and is part of how soundbars get their stereo image, but I’d like to know how they’re processing the audio to create such a wide spread. Pretty cool stuff!

It really is neat, expensive but there’s also nothing else like it. Ltt did a video on it and were blown away by the side channels and things where there were no speakers

Love LTT, not sure how I missed this one?? Thanks for the link!

It’s all time and phase based, in addition to multiple drivers that are individually controllable.
If you are interested in it - look into Klang in-ear monitoring; it’s designed for live music but can be used for all kinds of things.

I’m not going to dig into it for Sony but will add that phase usually does this. If you have one speaker in phase and one out of phase on the opposite side the sound “comes from everywhere” which is undesirable when it comes to setting a front sound stage.
I’d imagine if you those Sony units use multiple drivers that could switch phase live by driver it could use it in cool ways.
Totally bullshitting here though

Is this created by using phase shifting?

They have that on ps5. It is software based. It can make any soundbar sound like it has speakers behind you.
Bacalacon t1_iy4250r wrote
PS5 3D audio is quite an improvement but I honestly never felt sound coming from behind, just mostly from the sides
BrewKazma t1_iy44qiy wrote
On mine it seems to come from everywhere. Its kind of off-putting .
Bacalacon t1_iy4lbam wrote
Man I wish that happened with my soundbar. On headphones it's glorious tho.

What sound bar do you use
BrewKazma t1_iy4racn wrote
A cheap Bose one.

The worst is when a game has really high quality chatter as ambient noise. So many times I’ve taken off my headphones and looked around because I swore I could hear someone right behind me.

Usually that's the results of room acoustics. Software can't fix everything.

It might be an implementation of HRTF - head-related transfer function.

That is exactly what it is. The new Tempest 3d engine.

Oh, cool. I'm not familiar - will go and investigate.

That's just what I need while I'm driving my car in traffic. Sounds unexpectedly coming from behind me.

Car manufacturers are missing a large untapped market here. They could start marketing their 100k luxury cars as affordable tiny home replacements given that the median new home sale price is now north of 400k. Just pop a 4K screen in for the windshield and add a coffee maker and you’re good to go.

I've always wanted to shit in a BMW without being ejected from the dealership.

You know all cars have rear speakers already right?
ImGCS3fromETOH t1_iy6fy60 wrote
Not surround sound systems though. At least not the ones I drive. Hearing speakers that are mixed and balanced but still playing the whole audio track is one thing. Hearing isolated sounds from the rear speakers would be something else entirely.

It's SCIENCE!
I want to incorporate that technology with one of these: https://m.youtube.com/watch?v=5z1I1grocF0

You can call it science, I call it sorcery! hahah

Sony also has tech that turns your TV screen into one big speaker.
swettm t1_iy4014p wrote
These types of features (spatial audio, HRTFs, beamforming, etc.) are actually pretty straightforward and well known techniques, and like machine learning, we're just now getting to a point where we have the hardware to properly implement them.
