Summary: Dont preset 100% mic volume

I am pretty sure this belongs to a backend package and not the frontend.
I have two seperate microphones that have the best sound quality when the "mic
volume" (amplification) is set to 10%.
It is really weird, I think on other operating systems there dont even is a mic
volume, and in fact its only software amplification after all, so it will
worsen the sound quality.
On 100%, which is the default, my audio is completely useless, unsaveably
oversteered. I actually tried to save some with Audacity, still unusable
sounds.
Alternative:
Some way of calibrating the mic and presetting that volume for this device is
needed. You never need to change the volume!
But 10% for two of my mics (internal and headset) brings the best audio
quality, which is very counterintuitive.
The auto-adjustment could be to initially just:
- enable the mic
- record the sound
- decrease the mic volume until there are sections of total silence
when there is no total silence there is background hiss, which means the mic is
over-amplified. So the calibration should be pretty easy.
How it is it seems like a desperate "the user can change it so it doesnt have
to work normally" way. On Windows or Android this doesnt even exist, for
obvious reasons.
If just setting 10% works for all devices, this may also be an option. Or
preset 10%. But calibration would really be great I think
