TCP socket for audio transmission on localhost

Question

Hello!

I found code of simple client - server application using TCP sockets, written in C#: http://www.csharphelp.com/archives/archive127.html . It makes possible to send and receive text. What I'd like to do is to send audio from one application to the other, I don't have to have communication in the opposite direction. [b]Can you help me, please, how to change the code so that it can send audio, not text?[/b]

In general I've got Skype and Sphinx4 (speech recognition engine). Normally Skype sends speech to the speaker and Sphinx4 receives speech from the microphone:
( Skype -> speaker ) AND ( microphone -> Sphinx4 )
I'd like to change it to:
( Skype -> Sphinx4 )
However I guess it cannot be done directly, so perhaps it should be:
( Skype -> socket -> Sphinx4 )
And now my question is how to send speech from Skype to socket. I will take care of things connected with Skype later. Now what I'd like to do is only to know how to send speech instead of text in client - server application.

Greetings!
