<p>Some programs might have their own methods of streaming to Icecast. However, anything you can listen to on your computer you can stream to the apradio Icecast server.</p>
|
||
<h1 id="create-a-null-audio-sink">Create a null audio sink</h1>
|
||
<p>Enter <code>pactl load-module module-null-sink sink_name=stream</code> on the command line to create a virtual output named “stream” which doesn’t actually point at a sound card, but allows other programs to capture that output before it’s dumped. Pulseaudio creates a ‘monitor’ for that output which you can use as input for another program such as darkice. In this case it will be called “stream.monitor”. Darkice will be using stream.monitor as it’s audio input.</p>
|
||
<h1 id="install-and-configure-darkice">Install and configure darkice</h1>
|
||
<p>The default systemwide darkice.cfg is at /etc/darkice.cfg. You can edit this but it's better to copy /etc/darkice.cfg somewhere else (e.g. ~/darkice/darkice.cfg) and use different darkice configurations for different streaming setups.</p>
|
||
<p>Configure darkice to send audio from the monitor of the newly-created output to the apradio icecast server. Most settings can be left as default.</p>
|
||
<p>Only the relevant options in darkice.cfg are shown below. See a complete example <a href="./cfg/darkice.cfg">here</a>.</p>
