The data you get is PCM, you cannot *really* tell if it's clipped but you can measure the received amplitude and determine whether it's close to the maximum possible. In a new program I am writing I show this info. The overload value in DLLCore is something like 90% of the maximum peak signal which can be returned (I can look at the source if needed).
Can you explain exactly what you want to do and what you want to see?

I am fiddling with a new sound card, and am wondering if there is a bit of _Windows_ software which will read the output of a standard audio device, and present the data directly? You can almost do this by looking at an FFT display, and looking for clipping, but I was looking for a more direct, and quantifiable reading. Programs using AE4JY's DLL core will tell you when you are overdriving it, but that is pass/fail.
