One nice thing about having the VU GUI is that you can actually see the levels, which may initially help you set trip points in your software when checking for sound levels to steer events. You can always regex out the sign, but that makes coordinating the number with the GUI reading a little difficult. The VU meter recommended below uses dB, so when you do your level checking, it will be done in negative dB, which is not a problem for AHK. Keep in mind that the raw numbers from the soundcard may represent different scales such as dB or absolute digital values. In the future, I may poke around with some VU meters and extract some code that derives just the numbers without the VU GUI. I offer the following less-than-optimal solution that worked very well for me. Personally, I do not have time to learn windows API. It's plainly obvious that if VU meter software exists, programmers have a way of getting the numbers. The ability to monitor sound levels is an indispensable & powerful feature. I suspect that someone out there already has a good solution to this involving solely numerical extraction.
