Fourble is a website that allows users to create podcasts from online hosted MP3 files. Its website lists the podcasts that it broadcasts, which include various audio dramas and old time radio shows.

Fourble builds podcasts out of existing MP3 files. Feed it a list of files hosted anywhere online, and it'll give you a podcast RSS feed to subscribe to, delivering the episodes at a rate of your choice. Once you've set a Fourble podcast up, anybody can subscribe to the same feed, either from the same point as you or from the beginning.
