REW Quick Microphone Measurements Ghetto Style. Quick and dirty studio microphone response tests.

This is a specific case video but might still be useful.
In the event that you also have a measurement microphone, a copy of Room EQ Wizard on a computer, and an intense boredom or curiosity about the frequency response of another microphone, this is a somewhat poorly constructed tutorial on making "quick and dirty" comparative measurements of your device in question.
There are likely all kinds of missing details.
Enjoy.
