I wouldn't recommend using a codec that is equivalent to mp3 with a digital audio processor. The dueling algorithms will cause the audio to sound horrible.

MaxxKonnect for STL

The AAC codec is far more efficient than mp3, and doesn't beat up the audio badly at all. If you're dealing with a bandwidth limitation, it's a very good option. I recognize the dueling algorthims issue. However, it's all a trade-off. You have to pick what you want to optimize. For a backup STL, if you're going to be on it a while, lower bandwidth wins. And, frankly, we're already cascading codecs everywhere anyway. Nice if you can avoid it, but it's probably happening a lot.
We're feeding KSKC and KSKP with 48K AAC because 128Kmp3 would bust our daily data allotment with hughesnet, which is all that was available when we built them out.
I wouldnt say its great but its decent.. and its better than no radio at all.
Here's the feed:
You guys using abbreviation for everything, Some I don't know, STL, MK
Sidebar: you make me remember my first "STL" for my station in Ecuador in 1964. We had the output of our Gates "Yard" board and the Audimax run into a PA amplifier. That fed about 6 km of fence wire! The tin coated steel wire was strung of 2cm square 24cm long pieces of wood with an insulator screwed to each end. The wood bars were mounted with tensioned wire of the same kind around utility posts, running all the way to the site ant which the audio was restored to 600ῼ to feed the Volumax and the rig.
The open wire line had two wood bars every 10 pole so we could flip top and bottom.
I moved to a low power FM link after a year of that! Competitors would periodically cut off a block or two of wire, knocking us off the air until I drove to the location with a ladder and replaced the missing wire.
That is great David.
Old technology is interesting in its simplicity and ability to be durable and cost effective with no licensing cost.

David, it is very tempting to ponder ways of implementing what you described, in the situation you were in.
The various ways to implement balanced type lines, vs unbalanced. And how a ground return might work. As we know, what works fine a DC, or 60 Hertz may not work well if an electromagnetic field is present.
As I recall Scott Fybush and other sources report, a Las Vegas market transmitter site uses one wire to convey primary electric power up the mountain road. The electrical path is completed by Mother Earth. Electrically, you might say the site is a 24/7 low level lightning strike. I am not saying the site is a a hazard, because engineered correctly it is perfectly safe.
However, at transmitter sites and even around the house, apparently benign "neutral" or "ground" current flow can cause hum, or kill you. And voltage drop to "earth ground" does not happen in one inch, even on the ground.
Safety first, eyes wide open.

And don't wear watches, metal rings or, worst of all, dangling necklaces with metal items on the,
When you think about it, most higher power transmitters or machines that use split phase or three phase power don't even use a neutral, just building ground. And go back to the transformer pad or utility pole and where is the neutral made? A ground stake at the pole or transformer.
That's the case with any poor ground. Where you get 60hz buzz or hum is from ground loops.
