Note that you can find posts that have audio or video in them by clicking on their Category in the right side bar.
Using a site I found that extracts audio from YouTube videos (this one actually works) FetchMP3.com I’m able to add some more audio files. I attached them to their individual video posts but here’s the links as well.

While I’m at it I’m also including this mp3 from a Duke University podcast. Especially for those of us who don’t have much experience in the market, this talk is interesting. The talk is called The Black Swan Theory.
