Any omni is fine. In most cases with measurement, you aren't entirely concerned with showing a completely accurate frequency response. The decay times and overall patterns are what is important. Considering you're just using them to compare them to each other, it shouldn't matter how accurate the omni is, as it will equally affect each measurement the same.groover wrote:Any leads on an "affordable" mic to use for room measurements?
I have two omni mics available: a Pearlman dp1 with a cardioid-omni switch, and a modded Oktava MK-012 with an omni capsule. I have doubts as to how flat either of them are.
With that said, the Behringer ECM8000 is the cheap measurement mic usually suggest by most folk.
