Earbud DIY mic calibration for RC and test of the new calibration file import feature

[canard]

You still need to match the level of the corrected frequencies (up to 400-500Hz) with the higher frequencies. If you don't the final result will be bass light or bass heavy.

you can also think that I could respect the speakers' biases concerning the bass or the response under 400/500hz but just try to reduce the acoustic accidents..and that is a sacred sport..to be taken up manually and not automatically..


ps I only use the peq on the subwoofers ( internal) and the headphones ;-)
I only reacted to the approach of making a "cal"
I will leave it there..I do not master this subject ( I basically know the measurement on speaker not ""rc""" .... ;-) )

delaying acoustic accidents at the listening point is already a considerable effort... ;-)

(that's why I wouldn't even try to use an auto rc mode that would try to fit it into a curve ;-) but that's personal... preferring to act at the loudspeaker ...upstream)

(some images of the observations with rew of the bass with calibrated mic, your samsung mic without cal then your cal carried out? ;-) )

It is all in the first post of the thread.

stop for me.. ;-)

I just wanted to point out this well-known method of observing the bass of speakers which could be diverted to create a file starting from a calibrated mic... or at least explain it a little...if it gives some people ideas
;-)

your specific measurements in very close field just for the serious to realize your cal?

The first post explains the procedure of using MMM to create a microphone calibration file for a non-calibrated microphone easily, against an already calibrated measurement microphone.

Posts #9 and #16 show that such a 'simple' calibration file aligns very well against another one created using the more precise nearfield driver measurement method, which you seem to advocate.

So in my opinion all the data is already provided.

for you ( microphone and sound card calibred)
example of the cleanliness of a quick measurement with this method... here in ...1/48 smoothing ...no interraction with room
very fast and easy...produces a clean and perfectly reproducible curve....
(comes close, by far, to the standardized calibration methods of microphones... which of course uses captures at very short distances (they are in small closed cells))
