Click on the "MuSE" icon on the desktop :

Alternatively, you can open a terminal and type the command "MuSE".

The application should start and the first thing you see is something like this :

As you can see the main window is a playlist where you can load audio files to stream them.

Above the main window, there are several buttons that will let you configure your interface and stream :

: this button will let you add more playlist, each of which has a volume control so you can mix between different playlists.

: this button is used to activate/desactivate the microphone input.

: this button is used to activate/desactivate the sound output, this is useful when you experience some problems of feedback.

: this button will let you configure your stream and start streamming.

: this button are the vu-meters that lets you monitor the sound level and the network traffic used by your stream.

: this button opens the credits page.

1. the first step is to configure your playlists and prepare your program
you can add another playlist using the "Add Playlist" button : , a reasonable setup will use for example two playlists like this :

You can click indepently on each "Play" button in the playlists and adjust the volumes to the levels you like.

For each couple of playlists, you also have a cross-fader below the playlists that lets you pass progressively from one playlist to the other.

For each playlist, you can configure the playing mode which is one of :

• single play : the selected file will be played once and the playing will stop ( not passing to the next ).
• loop : the selected file will be played as a loop.
• continuous : the files will be played one after the other and when it will reach the end of the list, it will restart from the beginning.

WARNING : there might be some problems in decoding files, as the support for mp3 seems to disapear little by little. Always prefer to encode your files in Ogg/Vorbis, at least for MuSE.

2. the next step is to connect and start streaming
once you can hear some sounds coming out of your playlists and speak in the stream using the microphone button : , you can connect your stream to an Icecast or Shoutcast server using the connect button :

Clicking the connect button, the following window should appear :

In this window, you have to fill the following information fields, the one noted in red are mandatory, the stream will not work if you don't fill them :

• Host: this is the name of the server you will stream to, in our case, we will use giss.tv.
• Port: this is the port where you will stream to, in the case of GISS, it should be set at 8000.
• Mnt: this is the name of your channel, it should be set for example to my_channel.ogg.
  WARNING : it should be an .ogg mountpoint here, MuSE doesn't support anymore mp3 streaming.
• Pass: this is the password you received when you opened a channel on giss.tv, it should be composed of 5 characters or numbers.
• Quality: this is the audio quality of your stream that can be comprised between 16kbps and 128kbps.
  The default is set to 16kbps, which is very low, it is probably a good idea to use an average value of 48kbps to 64kbps.
• Mode: mono or stereo : if you don't use stereo effects in your program, it is sufficient to emit in mono ( the default mode ).
• Record: if you want to record your program at the same time as you emit it, you should enter here a filename and press "Record now!"
• Name: the name of your program that will appear in listeners clients
• Url: an URL related to your stream, that can host useful information like the program grid, recorded programs, ...
• Description: a description of your stream.
• Login Type: there, you have the option of chosing between "Icecast", "Icecast2" or "Shoutcast" server.
  this is mainly for historical reasons, now most of the time, we use the Icecast2 option, which is the default.
  Shoutcast is a proprietary server which not supported or recommended by GISS.

If you want to control more precisely the quality of your stream, you can also enter the "Expert" mode that lets you fine-tune more parameters :

There you can set up the following parameters for your stream :

• bitrate: this is the average bitrate of your stream, an average value should be 48kbps to 64kbps.
• frequency: the sampling frequency of your stream, a frequency of 22050Hz is an average and the default value..
• frequency filtering: here you have the choice between "auto", "manual" or "none".
• lowpass Hz: in case of a manual frequency filtering, this is the lowest frequency that will be encoded in your stream.
• highpass Hz: in case of a manual frequency filtering, this is the highest frequency that will be encoded in your stream.

NOTE: Using the expert mode is optional, the presets can let you control the general quality factor, that is sufficient in most of the cases.

3. the next step is to check that the streaming is working
once you have clicked the connect button in the icecast configuration window, you can go to the vu-meter window to check that everything is running fine, using the vu-meters button :

If everything is running fine, you should see the audio level and network traffic vu-meters moving like in this image :

If the volume meter stays at 0, you probably have a problem with decoding your files, you should try to encode them in .ogg format.
