I've done a number of explainer videos for website launches such as for Buddyfied http://www.youtube.com/watch?v=uUdtrGFZgMY causes.com http://www.youtube.com/watch?v=LXXAUqilOaw and on the front page of http://www.kitsy.io/
In addition to explainer videos, I've also voiced presentations such as this video form the Orange County Transit Authority http://vimeo.com/85755324, advertisements for services such as this video for SKLZ http://www.youtube.com/watch?v=j61yYa9jFLs, and student projects such as this http://vimeo.com/78893552
I have had no formal training. I'm a professional musician in two successful bands in Madison, WI, I host several nights at local venues on stage, I've acted in several local stage productions, and I have my own radio show.
My personal setup is an Audio Technica AT2020 condenser mic (XLR model) connected to an m-audio breakout box running through my late-2010 model Macbook Pro running Adobe Audition.
