Noise canceling device for microphone in open circuit?

Question

Electronics

I use a bluetooth radio in the car (that is, it connects to an android mobile phone in this way) with an external microphone (jack 2.5 mono connector - signal and ground from the microphone; it is normal, without its own amplification), which is displayed near the sun visor. I use this bundle for what it is intended for - to speak hands free. You can hear, I must say, I feel good, the microphone is brought out successfully, and the radio tape recorder itself, it seems, is not bad. Cuts the outgoing signal from the speakers, if it enters the microphone - no one complained about the echo.
But there is no limit to perfection. At a fairly high speed, with slightly lowered windows (smoking while driving has not yet been banned :) people complain about the noise. I want to get confused, put some device in the gap that could cut off homogeneous noises in real time and isolate the voice of the speaker (that is, me), and only after that send a signal (perhaps even with amplification of the useful signal) into the connector. Let, for example, with a delay up to a second.
I started to google - all solutions, I must say, are very complex, expensive and created for studio needs. Something simple that could be installed in the gap of the microphone, connect the power, and hide under the dashboard of the car is not to be found. For example, a video presentation of a similar solution for a few kilogreens: www.youtube.com/watch?v=M874m5YiGkk- a very effective thing, but it is obvious that it will not work.
The question is which way to go? I want to say right away that I don’t want to look for software directly on the phone - I think the path is wrong. I would like a universal solution for any device with bluetooth, which would be connected to the radio. Raspberry + soft? Which? Even if it's paid solutions. To have line-in -> delayed processing -> line-out. Maybe there are ready-made devices for the task at a reasonable price (maybe even professional voice recorders with an input-output signal without compression with subsequent processing)? Maybe an android tablet with the same software (again, what kind)? Which could take sound from the standard connector, process it, and send it to the standard output in real time.
Thanks in advance.

Answer 1

In my mother's car, I decided to transfer the microphone to the driver's visor, it will be much easier + there is almost no noise from air currents. But two nuances. 1) Under the visor, not next to it. 2) The microphone is regular in the trash. 3) Perversions like noise reduction - not cost-effective. Micro tear out of the headset any, and then leave it as it is, without tearing it out. If anything - write, I will help with the search for solutions.
