Podbean

Podbean (http://www.podbean.com/)is a free podcast hosting service that does for audio what Youtube does for video: it hosts the sound file, so you don't need to store it on your own server; it gives you embed code so your sound file can easily be embedded on a blog or webpage, and it gives you a slick looking playing for the end-user to use to play the file.

The process is pretty simple.  Register for Podbean with an email and password.  Record your podcast, upload it to Podbean, and then use their embed code to put the podcast on your website.

The free version of Podbean limits sound files to 100 mb total.

Joanne Littlefield and I co-hosted a Connect session on organizing and creating podcasts and using Podbean, available at http://www.coopext.colostate.edu/comptrain/co.shtml.  In addition, there are several video tutorials on sound file formats, recording podcasts and using Podbean available at the video tutorial page, at http://www.ext.colostate.edu/vid_tutorials/index.html#pod.
