If there's one thing I can't understand about modern wireless voice comms, it's this. We can push megabits per second of pixels, with low latency, over wireless with miracast, but can't figure out how to push 16-20 kHz of 8-bit audio signal full duplex? It makes zero sense.

The problem is processing power. Encoding of anything takes a lot of battery power, so the complexity must be kept at a minimum.

That said there is a successor called LC3 [1], but hardware support for it has been lacking as it's a relatively fresh standard.
