SHOUTcast is a streaming server which allows radio stations to effectively broadcast audio online (this is known as webcasting). It is powerful and stable, meaning you can throw all of your internet radio traffic at it without having crashes or other problems.
There are 3 stages to the broadcasting process. You don’t need any complicated or expensive software or hardware at your end either, a simple desktop PC and broadband connection will work fine.
