For context, LDAC is one of the few wireless audio codecs stamped Hi-Res by the Japan Audio Society and its encoder is open source since Android 8, so you can see just how long Windows is sleeping on this. I’m excited about the incoming next gen called LC3plus, my next pair is definitely gonna have that.
The standards are terribly complex and the reference implementations were originally written by the standards groups.
Then to keep compatibility everything has to be broken in the same way as the reference implementations which put more effort into “it works this time” than any kind of resilience.
