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.

reflection my use of "toy" was a bit too dismissive, falling into the same trap
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
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
for consistency, which would be the case with a single,
imprecise, mic, it is always the same
imprecision so all measurements are
