Dolby Atmos FlexConnect gets its first competitor at CES 2025

Dolby Labs’ Dolby Atmos FlexConnect platform is a clever concept. It’s software that’s designed to be built into a TV, where it performs some room calibration magic, ultimately letting you place your speakers anywhere you want, while still getting an Atmos experience. And now it has its first competitor: Fraunhofer UpHear Flexible Rendering.

Fraunhofer Institute for Integrated Circuits (better known as Fraunhofer IIS, or just Fraunhofer) — the organization that created the ubiquitous MP3 music format — will be demoing UpHear Flexible Rendering at CES 2025, exactly one year after the first demos of Dolby Atmos FlexConnect.

Just like FlexConnect, Fraunhofer says that UpHear Flexible Rendering will make it possible to place wireless speakers (just one, or multiple units) almost anywhere in your room, and the AI-driven system will automatically calibrate it to deliver optimized stereo or surround sound formats.

“Currently, users can only connect to one smart speaker at a time or to a fixed setup per room,” said Fraunhofer IIS’ product manager for UpHear, Sebastian Meyer. “With the UpHear technology, you now have the flexibility to conveniently combine any number of speakers into an immersive speaker cluster wherever you want. Party music in the kitchen? Transform your living room into a movie theatre? Operas in the bathroom? It is all possible without a fuss.”

One big difference between FlexConnect and UpHear is that UpHear can be integrated into a variety of devices, including TVs, soundbars, and smart speakers, which means you may be able to create an UpHear system without trading in your existing TV.

When Dolby announced Dolby Atmos FlexConnect, it said the first FlexConnect TVs would be coming from Hisense and TCL. Those still haven’t shown up (maybe we’ll see them at CES 2025), which gives UpHear Flexible Rendering a chance to catch on and possibly take the lead on flexible speaker systems.

While UpHear Flexible Rendering is a new offering, Fraunhofer’s UpHear technology portfolio has been around for several years. It has already been integrated into a variety of devices like Sennheiser’s family of Ambeo soundbars, where it provides surround sound virtualization. Different versions of UpHear have been developed for cameras, smartphones, VoIP devices, headphones, and earbuds.

Samsung, Google are attacking Dolby Atmos’ monopoly on 3D sound, and it’s going to get ugly
Dolby Atmos Under attack.

When you think of immersive, 3D sound for movies and music, one name usually comes to mind: Dolby Atmos. Despite the existence of competing surround sound formats and technologies,like DTS:X, MPEG-H, Sony 360 Reality Audio, and Auro3D, they barely register when compared to the juggernaut that is Dolby Atmos. With strong (and growing) support from movie studios, music labels, streaming services, game consoles, smartphones, and audio equipment makers, there’s little doubt that Dolby Atmos and Dolby Atmos Music have become the de facto 3D sound standards.

And yet, if Google and Samsung get their way, Dolby Atmos’ reign as the king of immersive audio might be about to meet its biggest challenge to date. Together, the two tech giants have been quietly working on an open-source and royalty-free 3D sound format known by the awkward name Immersive Audio Model and Formats. But if history has taught us anything, it’s that format wars are rarely fought for the benefit of the public. And even a free version of Atmos that’s every bit as good as the original could face harrowing barriers to adoption.
Why do we need another Dolby Atmos?

Is Dolby Atmos FlexConnect a potential soundbar killer?

In this day and age of tech, you can’t blink without missing something. So I wouldn’t at all be surprised if you missed a cameo that Dolby Atmos FlexConnect made during a recent TCL announcement. I mean, I almost missed it. Perhaps that’s why nobody is talking about it. Or … is there another reason?

I’m going to take a closer look at this new Dolby Atmos FlexConnect technology. Given the kind of power Dolby has in the industry and the fact that at least TCL seems pretty on board, I figured it's worth a quick conversation.
