Note that the only appropriate way to distribute an LFX is as part of a
complete audio driver package. Of course, if this is just for
experimentation/proof of concept then do whatever you want.

Oh, come on! There's a free version with some features limited for you to try
out, and the full version is only $30. If you have not done audio drivers
before, it will save you MONTHS of frustration.
If you are working on Vista, you can write a Local Effects Audio Processing
Object (LFX APO) to do this. This is a user-mode DLL that lives in the the
audio engine process. There is a sample in the WDK in src\audio\sysfx. It's a
little bit tricky to get one installed to begin with, but there are documents
available to help with that.
