Weird sounds after every shift

Ever since I got the car second hand at ever shift a turbo like sound can be heard and its starting to get weird because no one can tell me the reason!
when I shift from 1st to 2nd at 40 or 30 kph as I let go of the clutch and the gas peddle a weird sound like a whistle sound can be heard. At first I thought to my self its cool but now im so curious as my brother told me it could be dangerous. Basically any gear I shift to and let go of the clutch it does a turbo sound like shift and as I drive its gone! But once my foot is off the gas its sounds again and stays there till I apply little pressure on the gas!

please help me solve this issue! Thank you

You can start by checking the clutch assembly-could be the release and pilot bearings, clutch pressure or disc plate-

Could be an air leak somewhere on engine or hvac system? But why worry? It will either get better or worse or stay the same over time. You didn't say where you thought sound was coming from?
