I think all the local iHeart stations sound like crap, analog or digital. I don't know if it's a compression issue (as in mp3 bitrate, not the other kind) or some sort of digital link somewhere that's very lossy or what. But they all sound "swishy" and "watery" to my sensitive ears.
Anyway, when you run that crap bitrate audio through a second round of encoding (for the HD stream) it magnifies those issues and makes then stand out even more. The same is true of listening online, too. That stream is re-encoded just like the HD is.
It's obvious there's some cascading CODEC issue with them in HD, since they sound so bad while the Cumulus stations that used to run HD always sounded so dang good. No subchannels, better audio input into the HD stream…
Up in Birmingham they don't have this audio issue and the iHeart stations all sound a lot better.
My guess is either iHeart's cluster in Mobile and Pensacola were early upgrades to digital music on hard drive type systems and they never updated their libraries to modern music standards… or the engineer who originally set it up had a tin ear and couldn't honestly hear any differences. It's good enough for 90% of people, but that was before streaming and HD became realities.
