OtsAV is the tool of choice for many internet broadcasters. OtsAV integrates directly with Nullsoft's SHOUTcast broadcasting plug-in. This enables you to broadcast the output of OtsAV (including mixing, dynamics processing, and all) to a SHOUTcast server via the SHOUTcast plug-in. The SHOUTcast server then broadcasts your station for the masses to hear. See How to integrate the SHOUTcast plug-in with OtsAV.
