Introduction
This guide shows you how to configure your system to broadcast music online using Winamp, the Shoutcast DSP, and a Shoutcast server.
Software Requirements
In order to play the music you need Winamp Music Player, available at www.winamp.com.
In order to stream the music, you need to install the Shoutcast DSP Plugin available at http://www.shoutcast.com/download/broadcast.phtml. For installation help visit http://www.shoutcast.com/download/broadcast.phtml#pluginstall.
Activating the Shoutcast DSP
After downloading and installing the Shoutcast DSP Plugin, it needs to be activated within Winamp. To do this right click on Winamp to pull down it's menu and select Options -> Preferences.

In the preferences window, scroll down and click on DSP/Effect, on the right a window should appear with Nullsoft SHOUTCast Source DSP v1.9.0 (or something simillar). Click on this and the Shoutcast DSP Window should appear. Once it's open close the preferences window.

Configuring your sound Settings
With the Shoutcast DSP open, click on the “input” tab and click on “open mixer”.

Two windows will appear, one called “play control” or “master volume” the other called “wave in” or “recording control”. These two windows will appear ontop of each other. Using the taskbar at the bottom of your screen, select the wave in/recording control window.
In the wave in/recording control window, select the “What U Hear” option. This may be labeled as “Stereo Mix”, or “Master Mix”.

Note: if you do not see any of these options appear, in your Wave In/Recording Control menu, select options then properties. In the properties window make sure that “What U Hear”, “Stereo Mix, or “Master Mix” is selected and return to the Wave In/Recording Control panel.
In the Play Control/Master Volume window, make sure that wave, microphone and master volume are not muted
Setting up your Shoutcast Server information
With the Shoutcast DSP open, click on the output tab. Your shoutcast information gets placed here. Your shoutcast provider, or administrator should have given you the address, port number and password. Say our server address is shoutcast.example.com:8025 – that means that our address is shoutcast.example.com and our port number is 8025. The password is given to you by your shoutcast administrator, lets say the password is example. Here’s were we put that information.
- Your address, shoutcast.example.com goes here
- Your port goes here
- Your password goes here
The encoder option, keep it to 1, in the next step we will configure it to match your stream.

In the output tab, click on Yellowpages, here you can set up what people will see if they listen through Winamp.

Clicking on the Encoder tab allows you to set up the bitrate, and quality of the stream. This is very important because it can make you sound like a chipmunk. Shoutcast streams use two Encoder Types – MP3 or ACC+. The encoder settings enables the quality, or bitrate of the stream. The higher the quality of the stream the higher of the bitrate. Most streams are either 64kbps or 128kbps. Let’s assume our stream is 128kbps, here is how we set it up.
- First we click on the Encoder Type and set it up as an MP3 Encoder
- Then we select our Encoder Settings and select 128, 44.100kHz Stereo
