Reply to comment by Thathappenedearlier in LG Display’s ‘invisible’ speaker brings sound to any surface in your car by MicroSofty88

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
