A podcast is an mp3 or video file that can be downloaded and played on a computer or portable media device. Individual podcasts appear as episodes that are updated daily or weekly. By subscribing to a podcast you can receive automatic updates. You can also listen to podcast episodes here on this page. To subscribe, you must have podcasting software installed on your computer such as iTunes. I've never been the biggest fan of podcasts, in my experience they are never made well and there is always background and white noise in the background that makes listening to them unbearable. An intricate part of a podcast is the audio bed. Audio beds are background music that make podcasts more interesting than just someone talking. Another facet of making a podcast more interesting are ambient sounds which are random sounds that we encounter in everyday life, and are used in interesting, creative, and funny ways. A wonderful place to find ambient noises is PacDV. A great program that is used to make podcasts is called Audacity. Audacity is a free software cross-platform and recording application. It is available for Windows, Mac, Linux, and BSD.
