MTec89 : yeah, listening to shoutcast servers is not complicated, but that's not what he wanted. He wanted to send the stream from mIRC to the shoutcast server.

I don't know the specifications for that type of sending, but I think you'd have to connect to the shoutcast, and then, following the protocols, send the file reading for example 16 000 bytes every second for a mp3 encoded in 128 kbps (as 128 / 8 = 16).
