Dissonant Project keeps one host computer (named Ada) for audio streaming and to create free accounts for people and groups that want to use web radio in a way different from commercial broadcasters. If you want do do a non-profit program or talk about social ideas, keep in touch.

4- Configuration and installation

After creating a web radio account, you need to start the audio streaming. At this stage, you should learn how to install the appropriate program according to your operational system.

4.1. Linux


Darksnow software configures your web radio account and the Darkice transmits your data. There are many different Linux interfaces, we will only show you how to configure the software in Debian system (like Ubuntu, Kurumim etc.).  

Download the software

Log in your package manager (eg. Apt-get, aptitude, synaptic) and look for Darkice and then Darksnow.

1- right-click the mouse on the program to install and check it;

2- click “apply” and follow the instructions.

*Hint: Linux platforms are more stable and have better compatibility with various technical programs designed for streaming. They also have everything to do with free communication.  

Software configuration

After the programs are installed, open the Darksnow. To do that, press Alt F2, type “darksnow” and press “enter”.

 Filling in the form: Pick up your account information (server, port, mountpoint and password). You will receive them by e-mail if you set up the account with Dissonant Project. 


1- in the first window, type:

Destination: Icecast2

Server: ex.: ada.dissonante.org

Port: 443

Point: eg.:radio

Password: (your password)

Level of verbosity: 10

2- If you want to save the transmission, write a name on the Archive Dump. To identify the file to be saved, click on the File Dump button and choose to save the file transmission.


3- Audio options:

Format: mp3 or ogg/vorbis

Encoding: constant

Ratio of bits: 24

Fee: 22,050

Quality: 0.8

(if your PC is old, try 0.5)

Bits per sample: 16

Number of channels: 1 – Mono

Buffer: 10

Device: depends on the type of your computer's audio card. The /dev/dsp is the simplest device


4- Describe your radio

Genre: ex.: Alternative (program style)

Public: (yes or no?)

*Note: none of the data in item “4” is required, but they identify you on the internet.


5- Broadcasting

Press the start button. If it works, great! If not, check possible errors or write to us (dissonante@dissonante.org).

*Tip: To transmit audio files from your computer or to mix songs, use other program, such as Jack. Start simple, use only /dev/dsp. Then, try new possibilities.


4.2. For Windows


The program may be installed as a plug-in (enhancement) for players, such as Winamp or Foobar. Here we will teach you how to install a version that works alone, the Edcast Standalone.

- Go to http://dissonante.org/site/downloads/edcast_standalone_elame.zip and download the latest version of the program.

Double-click the downloaded file and follow the instructions (we recommend you to accept the standard Edcast configurations).

Setting up the account

2- With the window open, click the “Add Encoder” button. When a new window pop up, fill in the data of your web radio account.

4- Identifying your web radio

Repeat the procedures for Linux. Both Linux and Windows use this data to name the radios on the net.


5- Advanced Configurations

Use it only if you want to store your radio broadcast. Select “Save Archive or Stream” and choose a folder to save your radio program.


6- Saving Configurations

After typing all the radio data, click on “OK” to save the configuration.


7- Broadcasting

Click on “connect”. If the data is correct, the word “connected” will appear. Also access www.dissonantproject.org, click on “Online Radio” and check if you radio is listed.

If it doesn't appear, check for possible mistakes or write to us (dissonante@dissonante.org).

*Hint: mp3 and ogg/vorbis formats are different ways of compressing audio files. Both Linux and Windows require a codec (a coding and decodign device) to be able to broadcast in mp3 format.  


Advertising the radio link

With the transmission working, you just have to send your address to everyone. There is a pattern to be followed:

e.g. http://name.site.org:443/nameoftheradio or http://ada.dissonante.org:443/nameoftheradio

In case you forget your address, access the “Online Radio” section on the Dissonant site. Then click with the right button on “listen”. Copy the link of the new page, paste it on your site and advertise it to everyone.

 Most audio players (Winamp, Windows Media Player, XMMS, VLC etc.) open automatically the web radio link.
