Alright, alright, alright.
That Cross Spectrum Labs calibrated my mic too. Imagine that.
I'm interested to see how this develops for you. It's sooooo nice to be able to take measurements like this. You need a stand alone spl meter. Your phone might work for that with their 85 db max spl. It's good enough to calibrate a 75 db tone into REW. I've still got my trusty RS analog job.
Keep taking the pic's as you start hooking this stuff up.
