I'm not sure if it's quite what you are looking for but I use something called gPodder. It downloads podcast episodes and saves them locally.Thanks. What I'm looking for is the ability to download podcasts, as mp3 files, so that they can be moved into my file folder organization to be read and played by Roon.
That's how it worked in the old Apple podcast system and was all automated. I'd like to keep that style of system.
I just play them but they can also be exported to other locations (not automatically though).
Windows, mac, linux versions. https://gpodder.github.io/
The trick is, though, in order to subscribe to a podcast you have to find the underlying rss feed (xml file) which is sometimes pretty well hidden.
