That’s a good question??

He is a musician, so he has at least 2,but I think even 3 mics in the room- in 2 opposite angles, like triangle.But even 2, one on his (100% I'm sure) professional photo camera and other- the main reason of such sound -0:37-- a studio mic that can catch the noice way beyond those small mics chiros put on clients. Btw- Look:the door closed,windows too, and the room itself definitely is noiseisolated(he plays on those 🎸 instruments loud!) That's why his rooms should be noiseisolated.Ok, so the mic can be at 2m distance but the echo that this room creates I can bet ≈3 times louder when you put the mic near you but with doors& windows opened, plus with simple designed walls from sandwich panels or gipskarton(don't know the English word for that material). So that's how he is literally the Captain crackaman, CEO of KZfaq loud cracks.
