What is an Audio Podcast?
Audio podcasts are a relatively new phenomenon brought on by the drop in prices of home audio recording and computing equipment, as well as the ease of sharing items through peer-2-peer, social networking, and online music stores. Podcasting, whose name obviously comes from the generation defining iPod, is essentially a recorded audio file of a radio show. Radio has been traditionally broadcasted live, and with the Internet you are given the ability to easily just play an audio file upon request that was recorded earlier. In general, a podcast is often defined as a media stream that uses the RSS protocol of XML, and it can also be document based or video based. This is a more official term, though audio podcasts are often simply distributed as an audio file.
Conventional radio can cost quite a bit of money, but with new technology and the lack of a need for licensing and conventional distribution, this can be done easily and distributed for free. Today, audio podcasts are often recorded by people as a support to other work they do, such as filmmaking, acting, politics, writing, or anything else as a way of creating a dedicated recorded space for their views. Though podcasting, because of its ease of production using simple recording equipment and a home computer, is usually done in the "talk radio" format, there are occasionally times when music is included as well. The audience downloads the audio podcast, either individually or as part of a subscription, and then listens on their computer through their audio playback software or outside device, like an iPhone.
