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.
Isn’t the new default codec in BLE Audio LC3 free and open and high quality? And it’s required for BLE Audio support, so there will be more and more devices that support it.
LC3plus isn’t really HiFi. It’s designed to be low-complexity & low energy: https://hydrogenaud.io/index.php/topic,122575.0.html
LC3Plus is more then sufficient for transparent audio at the typical rates you will achieve with bluetooth, 160k is really low and you can normally sustain around 300-600kbps which is more then sufficient for LC3Plus. this test is IMO flawed for the intents and purposes for bluetooth audio
EDIT: LC3Plus caps at 512kbps, I cant remeber if that is before or after FEC (forwards error correction, not to be mistaken with PLC, Packet Loss concealment, FEC is kinda like raid, PLC hides dropped data)
LC3 is default and open, but not high quality LC3Plus is however it has a royalty (albiet very cheap)
