Nullsoft SHOUTcast Server runs as an application on supported operating systems, such as Windows 95/98/NT, FreeBSD and Linux. The SHOUTcast Server accepts connections by way of the SHOUTcast DSP plug-in in order to have a SOURCE Stream to broadcast. Once a stream has begun, the SHOUTcast server only accepts connections from other copies of WinAmp in order to broadcast that source stream to each listener. The effect is a micro-broadcast system that allows people to broadcast any content in any of the formats that WinAmp supports. Through the use of specialized SHOUTcast broadcasting plug-ins, audio from a microphone or any device attached to the Line-In port on the broadcaster s soundcard can be streamed by way of a SHOUTcast Server. The SHOUTcast server is the key to connecting many poeple to one another by way of WinAmp.
