I'm a student studying sound and i and recording sounds this is one of the recordings. This sound was made by having the microphone near a fridge door that was opening and closing.
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 features a glass front door of a suburban home is opening and closing. The opening of the door needed more gain which was added in pro tools.
