Wooden door. . . Key is quickly inserted into a lock, turned and the lock is "unlocked" - stereo 44. 1 khz 16 bit interior. . . Recorded with sony mini-disc recorder 2005.
A sound of someone trying to open a door. This is a really quiet sound. Recorded with zoom h4n and edited with audacity. This was recorded in a classroom.
Opening and closing the car door. Two doors opening and closing, generating audio with two different tones. Audio captured with zoom h1 in my garage and no noise.
The sound of entering a carousel door at an office building going around a few times and then exiting. There should be enough audio here to modify it as needed.
