Audio has been an important media element, and humans have been trying to record and improve the recording of audio for centuries. In the last 20 years, the format of audio files have become smaller and smaller, mainly with the goal to be able to fit more songs on a portable mp3 device. There are a handful of formats audio files can come in, for example, .wav or .aac. The most common formats we see are .wma [Windows Media Audio] and .mp3[MPEG Layer-3 format]. Audio is useful if we want to enhance a presentation, or simply listen to our favorite song.
Podcasting [Personal On Demand broadCasting] is a new type of media that consists of web shows that are downloaded through web syndication, making this form of media unique. Podcasts are portable, and are available to watch whenever and wherever you are [as long as you downloading all the available episodes!] Also, anyone can create a podcast. All you need is a a mic and/or a webcam, a computer, and a connection to the internet. You can find podcasts of just about anything.
Podcasting, more than the knowledge of audio, could definitely be useful in psychology. Podcasting opens up a whole new realm to communication and the way we share our information. I'm sure there are plenty of psychologists or professionals in the field of psychology that have their own podcasts, or subscribe to other podcasts that informs them of thing such as current research. Podcasting allows novices and distinguished members alike be on an equal playing field in distributing information.
Here's a link to a personal friend's podcast called "The Blender Show." He [Ian Elsner] centers his show around the open source animation software Blender, as well as the abstract ideas of animation.
