Icecast comes with a web interface that serves the audio streams as files. It includes an admin section which lets you see basic information and statistics. You can access it by navigating your web browser to your server address or domain and the port,
Streaming with a Source Client
Once the Icecast Server is setup you can use any of the compatible Icecast Clients, (also known as Source Clients), to transmit audio to the Icecast Server and to all the listeners. Usually the Source Client is installed remotely in the location where the audio is going to be transmitted but can be installed together with the Server if needed. There are a variety of options from free and open source applications like mixxx for DJs, IceS for complex automated setups and BUTT for simple microphone sharing; as well as many closed source solutions. A list of free and open source Source Clients can be found at Icecast’s app list
The scope of what Icecast is capable of doing is far beyond this basic setup. Visit the Icecast documentation to explore all the features that it offers, such as: stream relaying, advanced authentication, transcoding, public radio listings and more.
