I am not sure what the difference is between "sound.orf.at" and "on.orf.at" But if its easy to do, than the possibility of downloading audio from "sound.orf.at" would also be nice.

Eg: https://sound.orf.at/radio/stm/sendung/38167/klingende-steiermark

Currently I dont know the technical difference of these two sources.

Had a quick look. Weirdly enough, this is much more involved than orf on. It's a simple shoutcast MP3 stream, but extracting the URL for a specific show requires JS execution. E.g.

https://sound.orf.at/collection/4/47620/black-history-month-noomi-anyanwu-uber-black-joy

Just loading the raw HTML of the page doesn't give us anything. There are 2 <audio> elements in there. When you start playback by clicking the play button, one of the audio elements' src attribute it set via JS, but it's unclear how to get to that data just by downloading static HTML/JS assets.

OK, the frontend issues an API request to https://audioapi.orf.at/fm4/api/json/5.0/broadcastitem/2476251

where the last path element is the id of the show/broadcast. That gives us nice JSON which contains the stream URLs.

Now the question is how to map a URL like https://sound.orf.at/collection/4/47620/black-history-month-noomi-anyanwu-uber-black-joy to the id passed to the API.

@badlogic You may find some interesting information on those API calls inside the source code of JDownloader, see: https://github.com/mycodedoesnotcompile2/jdownloader_mirror/blob/main/svn_trunk/src/jd/plugins/decrypter/OrfAt.java#L510
