For those that don’t know what DAB+ is https://www.digitalradioplus.com.au/ I believe the US is looking at doing it too...DAB+ uses a lossy codec, just as with mp3 files.
There are no plans for DAB in the US, afaik. We do have digital broadcasting via satellite (Sirius/XM, a paid service) and a very poor IBOC system for terrestrial AM and FM developed by iBiquity (and now owned by Xperi).
