How To DJ In Second Life Using Mixxx

How To DJ In Second Life Using Mixxx - user interface

The most popular DJ broadcasting software used in Second Life is probably SAM, but for many the price tag of around $300 is very off putting. However there are alternative DJ broadcasting systems and one of the best has to be Mixxx, not least because its completely free. Mixxx is one of the most comprehensive systems available and this tutorial will show you how to DJ in Second Life using Mixxx as your streaming software.

For a while Mixxx was almost impossible to use on Windows to stream into Second Life (it worked fine with Linux and on a Mac), but after a few updates the software now works very well.

Configuring MP3 Streaming With Mixxx

For licensing reasons Mixxx does not come ready to stream MP3 files so this is the first thing you'll need to configure by adding a lame file.. 

1/ Go to  and download the LAME 3.98.4 file.

2/ Unzip the download, and you will see it contains both 32 bit and 64 bit lame files. Select what is appropriate for your system.

3/ You will see three lame files similar to the above. Copy the libmp3lame.dll file and navigate to your Programs folder. Paste the lame file into the Mixxx program folder.

4/ Rename the file you just pasted from libmp3lame.dll to lame_enc.dll. Close the Mixx file and you are done.

Note: Slightly confusingly there is already a file called lame_enc.dll in the package you just downloaded. DO NOT use that lame file because it won't allow you to stream MP3s.

Linux Users

The process is simpler for linux users. Open a terminal and type the following command:
 sudo apt-get install lib3lame0

Buying A Stream In Second Life

How To DJ In Second Life Using Mixxx - buying a stream

For an audience in Second Life to be able to hear you DJ you'll need to buy a stream. This is pretty much the same process as paying for anything in Second Life. First decide how big your initial audience will be. If you think it will be no more than 50 then buy a stream that allows for this size of audience. Otherwise buy a stream that caters for a larger (or smaller) audience.

Simply go to a place inworld that sells streams, right click on one and pay the box.

Once you have bought your stream you will receive a notecard which will contain the following stream details: 
  • The IP address
  • The Port
  • The password
  • The stream URL

Entering the Stream Details In Mixxx

1/ Start up Mixxx then go to Options > Preferences > Live Broacasting. You will see a window similar to the above image.

2/ Under the Type drop down menu select the type of stream you are using (either Shoutcast or Icecast).

3/In the Host space enter the IP of your stream. This is likely to be a (see above). Don't add any  'http:/wwww' section of the name. Leave the Mount space empty if you're using Shoutcast.

4/ In the Port space type the number from the notecard that is the port.

5/ The default Shoutcast Login is admin. If this space is empty type that in.

6/ Type your password into the space provided, then click the OK button at the bottom of the window.

Your stream is now set up in Mixxx and its now time to test it in Second Life.

Testing Your Stream In Second Life

To test your stream you'll first need some land where you have rights to change the sound in the About Land settings. If you don't have your own land then maybe a friend will help you out. This part also assumes you have loaded a play list into Mixxx (if not see below).

1/ Start up Mixxx then select Options > Enable Live Broadcasting. Once your stream is connected you should see a window similar to the image below. If your stream doesn't connect it is likely you have made an error entering your stream details in the step above.

2/ Now in Second Life open the About Land window and select Sound. In the space provided enter the URL of your stream.

After toggling the sound once or twice you should begin to hear your stream, although don't forget to allow for the time delay between what Mixxx is playing and what you can hear in Second Life.

You are now basically up and running as a Second Life DJ. All you need to do now is find a few venues to share your DJing awesomeness with other SL residents.

If you want to find out more about Mixxx you can view the online manual, but below is a few hints and tips to get you started.

Creating Playlists

You can if you choose have Mixxx manage all your music files, but being lazy I simply drag each music file  I want for a session to a playlist.

How To DJ In Second Life Using Mixxx

1/ Click on Playlists to the lower left of the Mixxx UI and then click on Create new playlist. After naming your playlist it will be available under the Playlists tab.

2/ Click on your new playlist then navigate to your music folder, then simply drag each file you want to the playlist.

3/ Double click each song in turn to load it into the decks.

Auto DJ

Some Second Life DJs like to select tunes to play as they go along but using an auto DJ feature is very common. Auto DJing with Mixxx is a simple process.

1/ Click on a playlist you have created then click on the first track. Hold down your Shift Key then click on the last track in your playlist so all tracks are selected.

2/ Drag them to the Auto DJ tab (just above the playlists tab). You have now added your playlist to Auto DJ.

3/ Click the Auto DJ button just under the right deck to start Auto DJing. Click again to stop.

Whilst Mixxx is in Auto DJ mode you can still change the order of the playlist as well as adding and deleting tracks.


How To DJ In Second Life Using Mixxx - volume

The Volume control is to the upper right of centre of the Mixxx UI. Hold down the left mouse button and drag the dial to alter volume. I find it best to turn the volume to max just before I start DJing.

Mic Control

The mic control is just under the left deck. If you can't see it select View > Show Microphone Section. As you can see from the above image, the mic has its own volume control. Toggle the Talk button to switch the mic on and off.

Thats just about all you need to know to get started using Mixxx to DJ in Second Life. Once you are confident in what you are doing we are always on the look out for good DJs at Chilly Bear so feel free to Midge Larkham about joining the Chilly Bear family.

  1. Hi so i have the latest version of Mixxx was currious if like in SAM there is away to mute the tunes in Mixxx so you can listen to them in world. i like to listen locally in world rather than muting second life. it helps me figure out if there is any issues or what not i can hear what other hears. please let me know if there is a way to do that.

    1. Hi Ari. Sorry for the late reply. The best way is to set up an external sound card. its not an expensive process, and I have written a tutorial on how to do this here:

  2. you can mute sound on mixxx and leave on in sl by clicking the pc speaker in taskbar .. clicking meter under one being used and then muting mix or sl or whatever one playing u don't wanna hear
