Engine sound
Here is the video I have made of my engine. I think sound is related to other issue I am experiencing which is at IDLE i can feel slight vibrations on brake/speed pedals. Sound you have heard disappears after minute or two of being on. These two problems might not be related.

I would agree with dave, compressor is suspect, and the rubber mounts for it which, on mine, failed and caused a shudder I could feel in the brake pedal and steering wheel.

Hello once again, thanks to Everyone for responding. Also, wanted to added one more thing regarding these sound issues: when driving at certain speed at lower RPMS engine is releasing squeaky noise which completely disappears once I speed up. My initial thought was it has something to do with gears, since sounds starts being release, it seems, just before gear switch.
Back on the topic, if it is related to air suspension, would it not be consistent, meaning getting this sound all the time? Because recently sound has vanished, car starts up and does not release any of this noise.
Sorry I am newbie. Got this car few years ago after getting driver's licence, but never had any issues and do not have tools/knowledge to solve them myself. Also, I feel reluctant to go to service first without knowing abstractly what is or can possibly be wrong with a care

I'd guess you are driving an older Audi.. & not using a synthetic based oil.
Worn parts are not going to get quiet after warming up.
Before your next service, add a 1/2 qt. of Marvel Mystery Oil to the crankcase and see if the engine doesn't get quite.
Then service and add the other 1/2 qt. of MMO and repeat with every service.
It would be positive to add MMO to the gas (for the valves) on a regular schedule.
Whatever the issue, cleaning things up can only help.. pc
