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.
