Check out Shoutcast, they've been enabling what you're describing since 1999.
I own and manage a platform just like this for the police scanner and amateur radio community

Thanks for what you do! I've used your software quite a bit, as I'm both a ham and a volunteer fire fighter.
No seriously though, why isn’t there a platform that would let me host, or listen to, live audio broadcasts? I mean, you could do it by twitch or youtube, but something optimised just for audio would be great. Somewhere out there must be people with interesting taste in music who’d be happy to curate shows I could listen to throughout my workday.
