Can I use any microphone for the auto calibration tools built into AVRs?

Also, how good are the auto calibration tools?

My method for calibrating speakers right now is using a noise app on my iPhone, and changing the speaker levels according to the app. Basically, I just adjust all of the speakers until they’re at an even DB using the test tone.
