There are both specialized web services and desktop applications for the task. Structurally, a podcast is an RSS file that contains links to enclosure files. Apple has developed iTunes an RSS extension for use with podcasts. iTunes significantly improves upon the capabilities of RSS by providing additional fields (such as keywords, duration etc.) for use in describing enclosures.

The most popular way of getting audio files for podcasting is to record them from the microphone and compress the file into MP3 format. There is a free program called Audacity (http://www.audacity.sourceforge.net), which does this rather well. To create and publish the RSS feed, you can use the Feed Editor software (http://www.extralabs.net), which is extremely easy to use.

headphones-iconDAB, or digital audio broadcasting, brought to the radio industry what the digital technology of cellular phones brought to the telecommunications industry–an alternative to analog technology. Using the Eureka 147 format, broadcast companies in Europe and the UK made the shift form analog broadcasting to DAB digital radio broadcasting; the Eureka format became globally standardized everywhere except in the United States.

The United States chose instead to have its DAB digital radio broadcasting formatted in hybrid-digital radio, which make it the only country to have done so, and more or less stopped the adoption of DAB digital radio technology altogether. In the United States, satellite radio has received all the broadcasters and broadcasting equipment manufacturers attention. Why?

Because satellite radio requires listeners to purchase expensive receivers, and in addition, to shell out the cost of subscribing each month. Radio listeners in other countries must simply raise their eyebrows at the prospect; they receive Eureka 147 and digital radio at no cost.

headphones-iconDigital radio is one of the biggest improvements in broadcasting since the introduction of FM. Digital radio signal can be broadcasted for more than 35,000 kilometers (22,000 miles) with complete clarity and high quality sound. You will never get static interferences while listening to over 100 radio channels. The idea behind digital radio has appeared in 1992, when the United States Federal Communications Commission granted a spectrum of the S band (the 2.3 GHz frequency) for Digital Audio Radio Service. The license to broadcast in that band was allocated to Sirius digital Radio and XM digital Radio in 1997. Now there are three companies that provide digital radio in the world: Sirius and XM in Northern America and WorldSpace in Asia, Europe and Africa.

 

Each of these companies offer different broadcasting systems, since the radio signal of each is proprietary. This means that you will have to buy different hardware depending on your subscription to one of these companies. However, there are three components common to all digital radio services: the digitals, the ground repeaters and the radio receivers.

headphones-iconThe introduction of digital radio has been one of the biggest innovations in recent FM broadcasting history. This radio signal can be heard at a distances of thirty five thousand kilometers and beyond.

That is more that twenty two miles with a clear reception, no static and more than one hundred stations to listen to. The inception of this concept was 1992 when the Federal Communications Commissions gave up the S band on the  radio wave spectrum (2.3 GHz) to Digital Audio Radio Service. The companies that were initially given a license to broadcast on this spectrum were XM digital Radio and Sirius digital Radio. Currently, there are three digital radio services broadcasting around the world: XM and Sirius in North America and WorldSpace in Europe, Asia and Africa.
