I think you might be going about this the wrong way. The thing is that streaming Internet radio is a protocol like activitypub, which the fediverse is built on in the forms of apps/platforms like mastodon and peertube. Internet radio already has apps, they’re called music players. Though I’m making some assumptions about your use case.

Are you looking to host an Internet radio station and have it live on the fediverse? In that case you’re better off with joining a funkwhale instance, include a link to your radio station’s address in your bio or banner, along with posting discrete shows or segments as podcasts on your artist channel. If you’re looking for software to do that I suggest AzuraCast.
