I've tried Googling to find a solution, but came up dry.

 

I want to listen to GeorgeFM over the internet for when i'm in an area with no coverage. I've tried their web stream and the app, but they both have an annoying distortion to them that I cannot stand.

I do however get line of sight to their transmitter from my house, so I get a pretty decent signal with no distortion on the bass or highs like their app.
What I want to do is send my receivers Zone 2 output to my PC's line in and stream that audio over the internet to my phone. And use the custom URL option in the TuneIn app to play.
I've looked into Shoutcast, but the free version only supports up to 128k on their free service and I would want to use 256k or 320k. Also I would prefer to just host the stream from my house. I have a PC thats on 24/7 anyway and 100/50 fiber internet.

Anyone know of any programs that would help with this little project of mine?

Or, if anyone from Mediaworks' streaming department is reading this, pleaaaase fix the web stream and up the quality. UpFM has an iTunes link for a 192k stream and it sounds awesome.
