If you’ve ever wondered how internet radio stations work and/or wanted to create your own, in this tutorial I will show you how. It is actually very easy, and you can set up your own radio station and begin broadcasting songs in about 10 minutes.
First of all, let me give you a quick rundown on how it works. You have your music player (I will use Winamp, get it if you don’t have it) and you play your music as you normally would. Through a plugin (which you will download and install), Winamp will send the music you play to the broadcasting server (which can be on your PC or on another one with a larger connection), and the server sends the music to the listeners, reencoding it to a better format, if you are so inclined. Note that the amount of listeners you will be able to support is limited by your outgoing bandwidth and the bitrate of the song you are streaming, so if you’re streaming at 128 kbps and you have 256 kbps upload bandwidth, you’ll obviously be able to support 256/128 = 2 listeners.
The programs I use are Winamp for playing, oddcast DSP for broadcasting to the server and Icecast for serving. You can use Winamp’s own Shoutcast plugin and server, but I prefer to broadcast in Vorbis because it’s smaller and has much better quality than MP3.
Let’s get started, then. Download Icecast from this page http://www.icecast.org/ (you presumably want the Windows version) and install it. Run it and click "Edit configuration" in the "Configuration" menu. A notepad window will pop up with various configuration options. My configuration is this:
You can copy it and paste it in your file, but make sure you change "hackme" to more secure passwords. Once you have done this, save the file and close the window. Click the "Start server" button and the list boxes below should be populated with various information, like this:

Your server is now ready for people to connect to it, but there’s no music playing, so let’s tend to that. Download oddcast for Winamp from this page and install it. Now, run Winamp, go to the "DSP/Effect" section of the preferences and click on "oddcast DSP v3". You should see the oddcast window pop up, looking something like this:
Click on "Add encoder" and a new encoder will be added in the box below. Right-click on it and select "configure". A dialog will pop up, asking for various information. For "Encoder type" select "OggVorbis" (or MP3, if you are so inclined), this will make you stream in Vorbis. Some people might not be able to have the available codecs if they’re running a very old version of their player (all newer players worth their salt support Vorbis).
For "Quality" I have entered -2, it is the lowest quality, giving you about 30 kbps bitrate and very acceptable quality. You can experiment with 0 or 2, going over 6 is overkill in my opinion (since 6 is what I use to archive music from my CDs), and you will be able to support more listeners if you have lower bitrate for the song.
For "Server IP" enter the IP of the server you’re running Icecast on (it’s "localhost" if you’re running it on your own PC). "Server port" is whatever you entered in the configuration, 8000 if you used mine, and "Encoder password" is hopefully something other than "hackme". I also use mono, because my connection only has 128 available upstream bandwidth and it doesn’t sound too bad.
Click OK here and then click "Connect". If you did everything right, the encoder should now connect to Icecast and begin streaming, like so:
The "Source Level Stats" section of Icecast should also change to include your stream, and will look something like this:

You can now tell people to connect to http://[yourip]:8000/stream.ogg with their players, and that’s all there was to it.
