10. Live Broadcasting - Start your own Internet radio¶
Live Broadcasting in Mixxx allow you to stream your mix over the Internet to listeners around the world.
The Using Microphones chapter has detailed instructions for including input from microphones in your broadcasted mixes.
10.1. Streaming Servers¶
- Remote streaming server
Mixxx allows you to feed your audio stream directly to Shoutcast and Icecast streaming servers. Depending on the number of listeners, streaming audio requires a significant amount of bandwidth. Streaming servers provide the required bandwidth and broadcast the stream to your listeners. A popular free streaming service is Caster.fm. A review of several free and paid stream hosts is available at broadcastingworld.net.
- Local streaming server
For experienced users, it may be interesting to set up your own local streaming server. This turns your personal computer into a radio station and listeners connect directly to your server. Mixxx as a streaming source does not need to run on the same computer as your streaming server. However, professional stations often run the streaming source on the same computer as the streaming server for stability and reliability reasons. Keep in mind that if want to stream audio to a significant number of listeners, you’ll need enough bandwidth. Read the Shoutcast documentation or Icecast documentation for server setup instructions.
10.2. Configuring Mixxx¶
Start by supplying Mixxx with all information needed to establish a connection to the streaming server:
10.3. Live Broadcasting Preferences¶
Mixxx works with Shoutcast 2 using the Shoutcast 1 protocol if you provide a stream name in. If you don’t provide a stream name, Shoutcast 2 rejects the connection (where Shoutcast 1 would accept this case).
Host: You can enter the host as either a host name or an IP address.
Login: As provided by your streaming server provider. Without this, you will not connect successfully to the server. The default login for Icecast is
sourcewhile the default login for Shoutcast is
Mount: A mount point is a unique name identifying a particular stream. For Shoutcast it is not necessary to specify a mount point. The setting must not be blank if you are using Icecast. Try the default
/live. If you haven’t been given a specific mount point you can usually make one up. It always begins with a
/(slash) followed by a text without any special characters in it.
Port: As provided by your streaming server provider. Most servers use the default port 8000.
Password: As provided by your streaming server provider, unless you run your own radio server. It is required to establish the connection to the server and to start the broadcast.
Do not enter a URL as the host!
does not work. Use
example.com in the Host field
8000 in the Port field instead.
Public stream: If enabled, this option adds your radio station to the Shoutcast/Icecast directory.
Enable UTF-8 metadata: If enabled, this option fixes broken accented and foreign language symbols in metadata, assuming the streaming provider has configured the server to support UTF-8 metadata.
Dynamically update Ogg Vorbis metadata: Due to flaws in some streaming clients, updating Ogg Vorbis metadata dynamically can cause listener glitches and disconnections. Check this box to update the metadata anyway. Some players that listeners can use have bugs that can cause audio glitches or disconnections when the Ogg Vorbis metadata is updated dynamically. If this is not a problem, you can enable this checkbox.
Stream name: So, what’s the name of your show?
Website: The website you would like your listeners to visit.
Description: Enter your DJ name and a short tagline.
Genre: List the main genres you play. This attracts search hits on stream directories. Genre must not be blank.
Bitrate: Selecting a bitrate of 128 or 160 kbps is common and provides sufficient quality to your listeners. Higher bitrates will use a larger chunk in your Internet connection bandwidth to stream and for your listeners to receive the stream.
Shoutcast metadata format
This allows to set custom metadata formats for the Shoutcast title field. Previously only
artist - titlewas allowed. For example if you were broadcasting as part of a station, you could add the station’s name or the presenter’s name in the title:
MyStation | $artist - $title. Or if you were doing a live mix with several artists, you could have:
Live mix by MyName - currently playing: $artist. Or even if you wanted a very unusual format:
Hey, I like $artist, here is $title by $artist.
The changes do not affect the case for the combination of OGG/Icecast2.
By default, Mixxx broadcasts artist and title information of the files that you play to your listeners. You can disable this feature and use your own custom metadata.
Enable custom metadata: Toggles custom metadata on and off.
Artist: Insert your custom artist metadata here, your DJ name for example.
Title: Insert your custom title metadata here.
Due to licensing restrictions, MP3 streaming is not enabled by default. For information on how to enable MP3 streaming, go to the chapter Activate MP3 streaming support.
10.3.1. Icecast vs. Shoutcast¶
Both essentially serve the same purpose. An Icecast server can stream either MP3 or Ogg Vorbis. However, although Ogg is more efficient and effective (you get higher-fidelity sound than MP3 at lower data rates) not all players can play Ogg streams. As a result MP3 is probably a safe choice unless you know your listeners can hear an Ogg stream successfully.
10.3.2. Broadcast directories¶
Generally your streaming server host adds your radio station to the Shoutcast/Icecast directory, if you enable the Public Stream option in .
Often streaming hosts will run their own directories. Check your host’s FAQ to find out. If you want to promote your streaming radio station even more, register at services like streamfinder.com. An overview of different internet radio directories is available at shoutcheap.com
If you have trouble connecting to your streaming server, check the configuration in the Live Broadcasting Preferences.
You may have selected the Ogg Vorbis format that is unsupported by Shoutcast servers.
You may need to check your firewall settings. Both Icecast and Shoutcast use two ports. If you are streaming on a port (for example, port 8000) then you need to open up the next port (port 8001) as well.
You may need to configure port forwarding if you are behind a router or your router will block requests to your streaming port (for example, port 8000)
10.5. Activate MP3 streaming support¶
Due to licensing restrictions, MP3 streaming is not enabled by default. In order to enable MP3 streaming you must install the LAME MP3 codec yourself. The following section explains how you can do that.
If you have activated MP3 streaming support, you’ll be also able to record your mixes in MP3 format. Go to the chapter Recording Your Mix for more information.
10.5.1. Activate MP3 streaming support on Windows¶
To activate MP3 streaming on Windows, follow these steps:
The download page includes 32-bit and 64-bit versions. Make sure the version you download matches the version of Mixxx that you use, not the version of Windows. If you are on 64bit Windows but are using 32bit Mixxx, you need the 32bit (“x86”) version of the LAME binaries.
Unpack the downloaded archive. You need a utility for manipulating archives like the free 7zip.
libmp3lame.dllto the location you have installed Mixxx, probably
Only if you are running Mixxx 1.11 or earlier, you must also rename
lame_enc.dllin the folder where you have installed Mixxx. Select to find out your version of Mixxx.
10.5.1.1. Windows Troubleshooting¶
Double check that the version of LAME you use (“x86” = 32-bit vs. “x64” = 64-bit) matches the version of Mixxx you use.
If you are running Mixxx 1.11 or earlier, did you rename the
Make sure you put the correct LAME
*.dllfile in the same folder that contains the installation of Mixxx you are using.
10.5.2. Activate MP3 streaming support on macOS¶
10.5.2.1. Method A: Download¶
To activate MP3 streaming on macOS, follow these steps:
Download LAME 3.98.4 Intel (macOS 10.8+ 64-bit)
Double-click on the downloaded zip file to unpack the file and you’ll get an installer package file
Double-click on the installer package file and follow the step-by-step instructions in the installer
10.5.2.2. Method B: Package manager¶
Another easy way to activate MP3 streaming is to use Homebrew or MacPorts, which are package managers like apt on Debian/Ubuntu Linux. They provide a convenient way to install many Open Source packages. Once Homebrew or Macports is installed, adding MP3 support to Mixxx is rather simple.
Open a terminal and type the following commands:brew install lame
Open a terminal and type the following commands:sudo port install lame
10.5.3. Activate MP3 streaming support on Linux¶
On Ubuntu and GNU/Linux-based operating systems MP3 streams can be activated by
installing the package
libmp3lame. Dependent on your Linux distribution
the package might be slightly named different such as
Open a terminal and type the following commands:sudo apt-get install libmp3lame0
