I have not tried that. I dont know what you want but it should not to hard extend my example. One approach is to open a direct connection via tcp or udp to a remote server and send the audio chunks to it.

I would do something like this:
Thinking about creating something like a web service which can receive data, on port 1234 for example and analyze the PCM data and send something back.

Like:

Class Webservice communication on a background thread. You should have 2-3 functions e.g. open connection to webserver, send data and compress data on the fly. Receive events from webservice and handle them.

On another thread you have your microphone recorder which has a instance of the webservice object.

The object should do something like this:
Record to iPhone audio buffer -> check if webservice is available and connect if not -> call send function and give chunk to the webservice send function.

Its pretty abstract and just an idea. Maybe there is a better way, but i think this is a good approach if you need to make secret analysis on your server.

Best,
Stefan
