dir2cast is a Web-based script to turn a directory of MP3s into a podcast automatically. It will automatically use the ID3 fields from your MP3s for the Author, Title, and similar fields in the podcast feed. ID3v2 is supported. The generated feed is cached and only updated if something in the directory changes. The generated feeds have almost full support for iTunes podcast tags. RSS Description, iTunes Subtitle, and iTunes Summary can be set by dropping text files in the same folder.
