The killer application for this technology is a bicycle bell you can use to break the trance of phone-staring pedestrians who are randomly staggering down the pavement.
I don't think this is how it will work. Broadcasting won't immediately interrupt others' connections.
I personally would not have predicted something like this was needed. How long has this been in the works? Now that I can see how useful this is, I'm amazed this didn't happen much sooner. Is this one case where "we" knew we needed it, but the tech just wasn't available?
I can't quite tell from the website, but I'm assuming we will need new BT antennas BLE Audio support before we can use it, which sadly means yet another generation of computers & smartphones have to come out before this can become ubiquitous.
Where can I find more about LC3 codec? What about LE audio specs? Is this open source or do they sell licenses for this?

The "Broadcast" mode is really an interesting concept - depending on the available range. There are a lot of potential uses for this technology beyond the basic. Of course "I can share my headphones with you" is great, in the day in age of watching moves on iPads in say a plane. However I think in a business setting the broadcasts could be used for all sorts of cool bits. Remember the TV's in airports running news on…

>LE Audio is Multi-Stream Praise be to the heavens - we can finally have Bluetooth headphones that don't revert to low-bitrate mono if the microphone is active.
YES! This has been bothering me for so long. I'm shocked it's taken them this long to iron it out. I hope the device manufacturers implement it soon. Edit: on second read, I'm not so sure LE Audio will address this issue. "Multi-Stream Audio will enable the transmission of multiple, independent, synchronized audio streams between an audio source device, such as a smartphone, and one or more audio sink devices." This…
The current issue is that headsets only support a single stream and A2DP isn't bidirectional, so the connection has to revert to the low-fidelity Headset Profile. Multistream means that each stereo channel and the microphone should operate fully independently. If this doesn't fix the issue, then it'll be a spectacularly boneheaded error, even by the standards of the Bluetooth SIG.

What is your use case for low latency? I understand that some want it for bluetooth headsets for videogames, where milliseconds mater - but beyond that? Also what about AptX LL? Or LLAC?
If you are a musician, try introducing a 10ms or 20ms delay and then play something on piano or guitar. Whether you notice it depends on a ton of factors which I’m not going to get into, but in general, at 10ms the music will feel sluggish and you will have difficulty playing on the beat. This can be verified with ABX tests if you like. The timing accuracy for professional musicians can approach 1ms under controlled…
One of the tradeoffs in latency for fidelity is that the two major components of lossy codecs (the filterbank and DCT) have an inverse relationship between quality of encoding and fundamental latency built into the algorithms.
The solution to your needs is a pro audio product developed by Shure or Sennheiser, not consumer electronics like bluetooth.
This literally addresses none of my complaints regarding Bluetooth Audio. Latency needs to be on the order of single-digit milliseconds. LC3 can achieve around 20. One order of magnitude too high. Audio needs to not sound like it's being played underwater. And give me 100 feet of range.
(Hint: If you're standing on the opposite side of the room from a TV, you're already at about 15ms of latency...sound moves at approx. 1ft per ms)
Many TVs are already delaying the audio by a frame or two anyway due to all the processing they do.
It's a very very different set of requirements than real time recording/instrument playback.
Will phones/computers that have bluetooth 4 or 5 be able to transmit bluetooth LE audio? Is it just a BLE feature that can be added in software, or is it a completely new standard?

It would be great for the array of TV's at the gym. Mine currently has a headphone jack on each treadmill with a keypad that you can tune into your preferred channel. I've taken to watching Netflix with Bluetooth head phones vs trying to use a wired pair while I run.
