Isn’t Bluetooth LE Audio supposed to be the one standard to rule them all? I was really hoping to see more handset and headset supporting it, but its news seem to have fizzled out. Anyone in the industry is able to share news there? Do we just need to wait? Is it encumbered in patents or too expensive to implement?

I'm trying to find reference, but I believe Fraunhofer has a bunch of patent encumbrances on LC3. Although maybe software encoding & decoding licenses are free? The tests where LC3 were chosen over Opus seem semi-dubious too, with only the general audio Opus codec tested at low complexity, in a speech test. I'm not sure but I think/hope Opus hardware implementations would not be hardware emcumbered, but I'm not certain. For headsets this can be a significant power consumption win. LC3 is not a high quality codec. It's a decent quality low bit-rate codec. Fraunhofer has a complementary lc3plus but it's unclear what grants of use there are on it to me. Qualcomm here with Apt & AptX has notably not released decoding grants of use at all. This allows systems to output AptX, to the benefit of Apt/aptx receivers having better support, and they all pay Qualcomm & I expect largely use Qucomm chips. This is opposite to the longstanding case of Dolby Digital 5.1 & newer, where many computers have decoders, but Dolby Digital or Dolbt whatever encoding is ultra ghastly super rare. People were keeping their ancient ass Nvidia chipset motherboards from 2001 because it was like one of the only rare options available. It's deeply scarring to me that so many of the important relevant ways to send data around, that define our digital world, are so jealously guarded secrets. We raise worse people on this planet by denying them curiosity & experimentation & playing with stuff, and a huge subsector of our critical AV systems is deeply shrouded in red tape & black boxes.

  This is funny, but google actually added opus for BT in recent version of Android, for some unknown internal reasons (maybe 5.1, VR or so). No one using it obviously though P.S. there is! https://hydrogenaud.io/index.php/topic,114566.msg1023511.html#msg1023511 https://hydrogenaud.io/index.php/topic,114566.msg1023511.htm...

    It's the first mandatory lossy codec in Android for microphones (so far they only required PCM and FLAC). There's surely a benefit in scenarios with more than 3 microphones, i.e. in Automotive...
