The Podcasts page allows you add subscriptions to podcasts which are often used to syndicated audio files using a URL called a RSS feed. This allows your LibreTime instance to automatically download new shows from the web.
In order to add a podcast you need to get the RSS feed. All podcasts available on iTunes have a RSS feed but it is sometimes hidden. See this issue on our github page#510for more information.
The podcast interfaces provides you with the ability generate Smartblocks that can be used in conjunction with Autoloading Playlists to schedule the newest episode of a podcast without human intervention.
