How to do Feed podcasting?

I want to know that how can i do the feed podcast in word press site and i want URL something like example.com/feed/podcast by the podcast...

Is there any plugin in word press for this or required any coding for this or any technique?

Please suggest me... Its very important for me...

is this what you need?

Podcasting Plugin

or maybe
Podpress
sorry if it didnt met your expectations.

just try to help.

I use the Bluberry PowerPress only first you have to submit your podcast to iTunes and follow the instructions after you install it it will feed the iTunes automatically. If you want to add the wwwwfeed/podcast/ to your RSS you can make a category call "podcast" add all your podcast to this category and when you submit your feed to iTunes you have to use the wwwwwfeed/podcast/
Hope this helps
