mIRC has nothing built in that can get the frequencies of what you're playing. That said, a DLL could obviously do it considering you already mentioned one that will. If you don't want that one, look up another that has the ability. I'm not sure why you don't want that DLL. As for COM, I'm not sure if that's possible. I don't know that Windows has any COM objects that watch frequencies, but there may be something that does. I haven't seen anything when looking at sound related COM objects, though.
