Hi, new to DSP, how are people setting their mic's up on there cars I have the UMIK-1 planning on setting the mic up facing the roof set at ear height using the 90⁰ file.

Does anyone have some sort of 3d printer adapter?

CheersChris

Usually we just hold it by hand, pointing up as it's easier, with the 90° cal file.
When I was measuring from outside the little tripod was fine, hold in place with a strap and a weight behind the headrest, in this case mic was pointing to the dash so 0° cal file.

But it’s good to keep your body inside for the future corrections, just more realistic especially for the woofer rsponse that can be disturbed by the legs.
You can use the nose point with your head fully rested on the headrest for time alignment, or whatever point that sounds good to you, as soon as it is replicable.
And then move the mic around your ears in different points for sweeps, same here, replicable points.

The right cal file is not that important as it only affects the highs, that will probably be tuned by ears anyway.
It’s more important to find a replicable method, so you can correlate what you hear with what you measure.
You can find many great tutorials, from simple to crazy advanced on DIYMA.
