Audio streaming


I am looking to send a audio stream from my computer, to my main server in mp3 format so people can listen with their mp3 client.

I have OS X 10.4.1. Can anybody suggest a good and easy software for the up streaming? The server have icecast for the streaming.

But with Nicecast I cant send the stream to my server. I have been trying Odd Cast on PC and there you set in config

Server IP
Server Port
Mount Point

etc. so it goes only to the server which will do the streaming (my server)
