Re: Calibrating measurement mics.
Jay,
A ''real'' calibrator will cost you about $500, I've looked into them before and never felt like dropping the money. In between ''I just want close'' and ''the right way'' there's not really anything. If you have a reasonably good measurement mic you may be able to use its stated sensitivity to set actual SPL within a dB or two, but you will need to know the gain of your measurement pre. Smaart should have this capability again eventually, and then Rational should give you mic profiles and if you have a mic on their list you just pick it and you're calibrated ''enough''.
I always just do the same thing Evan does, get close enough do the numbers mean something. Mostly I want to know the differences between my mics, but I want to know that broadband so even a simple calibrator doesn't do what I want.
p.s. If you do buy a calibrator, a pistonphone is the only way to go. The electronic ones are all way too unstable.
