.cal file for Avenson STO-2

[greiswig]

I have a pair of these mics, and intend to use one for my room calibration. Unfortunately, it did not come with a calibration file, although as you can see it's pretty flat. Is there a recommended way to have REW "assume a flat mic" or to get a .cal file that roughly corresponds to published specs like this?

If you can get a higher resolution image of that plot you could use FPGraphTracer to generate values for the plot and then create a 'generic' .cal file for the mics. The other option is to contact Herb at Cross-Spectrum labs about sending him your mics to calibrate them.

Just don't load a cal file.

You can make your own cal file, the format is straightforward and shown in the help.
