Why the hell opus still not in Bluetooth? Well i know - sweet sweet license fees (aKKtually, there IS opus codec, supported by pixel phones - google made it for VR/AR stuff. No one uses it, there are about ~1 headphone with opus support )

Opus isn’t patent free, and what’s worse it’s not particularly clear who owns what. The biggest patent pool is currently OpusPool but it’s not the only one.

Isn't it a strange coincidence that this shows up on HN while Claude Opus is also announced today and is on HN front page? I mean, what are the odds of seeing the word "Opus" twice in a day on one internet page?

Well it was released today

Very likely a coincidence.

The BT SIG moves kind of slow and there's a really long tail of devices. Until there's a chip with native Opus support (that's as cheap as ones with AAC etc) you wouldn't get Opus support even if it was in the spec. Realistically for most headphones people actually buy AAC (LC and HE) is more than good enough encoding quality for the audio the headphones can produce. Even if Opus was in the spec and Opus-supporting c…

They chose to make totally new inferior LC3 codec though.

Also, on my system (Android phone + BTR5/BTR15 Bluetooth DAC + Sennheiser H600) all options sound realy crappy compared to plain old usb, everything else is the same. LDAC 990kbps is less crappy, by sheer brute force. I suspect it's not only codec but other co-factors as well (like mandatory DSP on phone side)

They’ll have my upvote just for writing ML instead AI. Seriously, this is very exciting developments for audio compression.

Machine Learning is Artificial Intelligence. Just look at Wikipedia: https://en.wikipedia.org/wiki/Artificial_intelligence

Many people are annoyed by the recent influx of calling everything "AI".

Machine learning, statistical models, procedural generation, literally an usage of heuristics are all being called "AI" nowadays which obfuscates the "boring" nature in favor of "exciting buzzword"

Selecting the quality of a video based on your download speed? That's "AI" now.

Not that strange when you consider what “opus” means- product of work, with the connotation of being large and artistically important. It’s Latin, so it’s friendly phonemes to speakers of Romance languages and very scientific-and-important-sounding to English speaking ears. Basically the most generic name you can give your fine “work” in the western world.
