Default DIY Frequency Response mic?

I wondered if a regular PC mic can be used to mesaure requency response and if theres any cheap software out the to do it? Also do I fix the output wattage on the amp measure the power then adjust it to the right voltage then leave it for the hole response recording?

Thanks
Boscoe

No, their frequency response is not flat enough.

You will find very few mics flat out to 20khz (especially of axis) unless you want to spend a few $k. If you can test the mic or get one that comes with an actual f response plot that was measured (not generic to the model ) you can use it to determine your speaker response. (you also need to get rid of the room effects)

Behringer makes a calibrating mic for about a hundred bucks thats very flat. Its made for measurement purposes only, which is why it can be made for cheap. If you want a flat music mic, that will cost you thousands.

Look at one using the panasonic WM60-AY electret capsule which is hella cheap and works great.

don't buy the Nady one; it's crap

If you want to get serious with accuracy, a calibration service can measure your ECM8000 and give you a correction file. http://www.cross-spectrum.com/measur...mike_meas.html
