One of my friends had a door that sounded really nice. They were incredible and sent me a very nice small recording of the door opening and closing to upload here.
Numerous takes of door knocks from inside a house, from light tapping to heavy pounding. This recording is taken from a close perspective (under a meter, or 2 feet). 96/24 zoom h4n with onboard stereo microphones.
Opening a fizzy drink can (330ml). Initial hiss / open. The opening is boomy because the mic was very close, but i didn't eq it out because it sounds quite interesting.
