Create your own podcast: find links to audio files on the Web; huffduff the links (add them to your podcast); subscribe to podcasts of other found sounds.
While the site does a pretty good job of describing itself and the fact that it has a wonderful bookmarklet, I’ll also point out that Ryan Barrett has a video bookmarklet for it that “extracts the audio from videos on YouTube, Vimeo, and many more sites and sends it to Huffduffer.”
If you’re a podcastaphile, it’s a de rigueur tool. While I publish a listen feed on my website, you can also follow me on Huffduffer if you wish. If you’re using it, do let me know so I can add you to my “collective”. This will let me find the great audio you’re discovering.
I should tell Jeremy Keith more often I love that he runs this little service: Thanks for making the world so much brighter!
