SHOUTcast is a free-of-charge audio homesteading solution. It permits anyone on the internet to broadcast audio from their PC to listeners across the Internet or any other IP-based network (Office LANs, college campuses, etc.). SHOUTcast's underlying technology for audio delivery is MPEG Layer 3, also known as MP3 technology. The SHOUTcast system can deliver audio in a live situation, or can deliver audio on-demand for archived broadcasts.
