Internet Radio Station Software

Hello I was thinking of writing a internet radio station suite for my disitation but was not sure on where to begin.

i thought about what was involved and this is what i need help on finding material / examples

1. Extracting the audio data from the users microphone
2. Extracting the audio data from an MP3
3. allowing the user to switch between the 2
4. sending the audio data over TCP sockets
5. Making a client that buffers this data
6. making the client play from this buffer

any ideas for useful articles ?

No offense dude , but if you haven't started yet or don't know much from where to start , then you're not gonna make it .
