Podcast is a neologism made up of the well-known MP3 playeriPod( Apple) and broadcasting. It is the collection and provision of audio contributions, so-called episodes, on the Internet and downloading from the Internet.

The process involves recording audio data, compressing it into a suitable audio file format, such as MP3, Ogg Vorbis, Adaptive Transform Acoustic Coding( ATRAC), WindowsMediaAudio(WMA) or others, and making it available in the podcasting server. In order for the interested party to find the audio contributions on the Internet, they are published by means of RSS feed or Atom feed with the corresponding web address.

Interested parties can find the publications of the audio contributions in the podcast directories ( and can download them to their computers with a suitable podcasting client and play them with the appropriate audio codec. The RSS feeds are text files in which the audio entries, their file format and length, the date, etc. are specified; however, they do not contain the audio files that are stored on the web server. If you have chosen MP3 as the file format, you can use the ID3 tags and extend them with certain information.
