Definition

Creating a podcast

• Microphone• Audio Recorder software• Media Player software• Audio Editor and MP3 Encoder• Reliable internet connection• RSS feed• Pod catcher software

Publishing a Podcast

To publish your podcast to the internet, you usually need to do the following:

• Host the audio files on a web server, a website or a blog

• Create an RSS Feed – this is the feed that your listeners subscribe to so they can automatically download new audio files of your podcast

Storage

The amount of storage you need for your audio files will depend on the following:

• The length of each audio file• The audio quality of your MP3 files (the higher

the quality the bigger the file)• How often you produce audio files• How many past audiofiles you want to make

available at a time to your listeners

Bandwidth

Bandwidth is the amount of data that your web host allows to be transferred to and from your web site. “Capacity channel”

Listening to Podcasts• Listeners can subscribe to podcasts through RSS feed. New audiofiles

are automatically downloaded as soon as they’re released.
