Looks a lot like the old Radio Shack analog meter, but you have no way of knowing which capsule it uses. I've not seen this one before.

What is capsule?
The actual microphone element.

Is it possible to make calibration data in any way
Not unless you have a graph of its response, there's really no way.

If you just want to use it with REW to make relative measurements (as opposed to absolute), then you could use the old RadioShack cal file. By this I mean, it can be used to determine if a particular location for your subwoofer was better or worse than another spot.

I have that same meter. Got it before I knew there were Cal files for the radioshack meter.


I would also like the files if anyone finds them.
