Take a look at NAudio (http://naudio.codeplex.com/), it might offer what 
you need. If you're developing for Silverlight, then, starting from v3 I 
think, MediaElement allows a MediaStreamSource descendant as its source. 
The descendant class is responsible for streaming the data in a format 
known to MediaElement to a stream, in chuncks of generated samples.

There may be lag and buffer issues when building a 
"on-the-fly-immediate-response" kind of application, but in general, it 
works very, very well. I don't have links handy, but google 
MediaStreamSource, and you're bound to find some useful examples.
