Digital Sound Processing in C# (and possibly SilverLight)

I need to do some basic and non basic DSP programming in C#. At its core, it includes the generation of a sin wave deciding its frequency i开发者_高级运维n Hertz. Then I'd like to Frequency Modulate it and maybe filter it.

Can you suggest any library to help me? Ideally this should also work in a SilverLight environment, as my aim is to showcase a ultra-basic SilverLight synthesizer.

Thanks in advance
