Do you know any interesting info about Fraunhofer's LC3 codec?

The Bluetooth SIG could have used Opus to address most of the needs, no?

For 160-350k a lower complexity codec probably made sense.

I think the same that Garf about it, basically they want to sell a license for it.

I wonder why they didn't just use Opus instead of creating a new codec?

If you look at the specification, it's basically Opus with a few marginal gadgets thrown in. I'm going to make a not-very-wild guess that you'll need a license for the gadgets, from the people who wrote the standard.

Not the need to make money by licensing proprietary tech to device manufacturers.
