Fellow ADE Sebastian Dorok put me onto Loudblog a couple days ago. This seems to be a step beyond DirCaster, the other PHP podcast publishing tool I posted about recently. From their site:

Loudblog is a sleek and easy-to-use Content Management System (CMS) for publishing audio content on the web. It automatically generates a skinnable website and an RSS-Feed for Podcasting. Just upload your audio files, add some notes and links, and you’re done!

You can see Loudblog in action at the author’s blog. (Looks like it’s skinned to look just like the default WordPress theme.) I like the play controls that are included with each podcast post. This looks like an excellent podcast publishing option for anyone with a Web server that can run PHP.
