It all starts with one station in your home office but who knows where it can go from there? If you’ve got dreams of being an Internet radio jockey you can get some ideas about equipment startup from this setup that [Viktor's] built for a friend.
He started out with a plan to have a station that offers twenty-four hour streaming but also supports live broadcast. Two computers are used in the setup. The first handles automated music broadcast and live mixing. This box has two sound cards, one is used for the automated music by feeding the output into a sound mixer that is a separate piece of hardware. The output of that mixer feeds back into the second sound card on the box. This secondary card outputs the final mix to the computer speakers.
The second computer is where a lot of the live broadcast work is done. Any steaming guest (using VOIP or Skype, etc.) come in through this box as well as jingles and sound effects used during the feed. Its sound card is also connected through the external mixer and joins the final feed headed into one of the sound cards on the primary computer.
In the end the Internet connection for the system isn’t beefy enough to reliably support a streaming station. For this a dedicated streaming service is used. It receives the live feed and then uses its increase bandwidth to propagate the signal to listeners anywhere in the world.
