Re: [regsaudioforum] Measurement Microphone
- Question: As long as the calibration file is detailed and calibrates an individual (as opposed to generic) mike to a known standard reference, such as an expensive B&K instrumentation mike, does it matter at all how wildly variable the inherent response of the particular mike is before calibration? I think that is what TacT is doing with their mikes. The mike is cheap, but assuming the calibration file is detailed and is based on an accurate standard mike, would one get any better results by using an inherently flatter mike with a suitable calibration file applied to that inherently flatter mike?On the TacT forum, there has long been discussion of the supposed variations among the responses of the TacT mikes supplied with the TacT electronics, as well as whether or not the calibration files are accurate. I'm not sure how one can determine calibration accuracy without actually owning a mike you "trust" to be truly flat, such as a $5,000+ B&K.

Precision doesn't usually come cheap is my main point. Linkwitz has on his website a project
to make a measurement mic using a $2 electret capsule, but that project requires a lot of
The Behringer route may work for home audio because you are always measuring the same
room, you don't need absolute precision but only relative precision which is another name
for consistency, which would be the case with a single, imprecise, mic, it is always the same
imprecision so all measurements are affected equally.
