The sound of a "push bar to open" fire door being opened. It could also be used as the sound of a car door closing. Recorded on a zoom iq7, then mixed to mono.
My bedroom door being closed during a recording. Sony ecm-ds70p mic to a sony minidisc mz-n710 acting as a preamp into my edirol ua-25 audio interface.
This is from my front door before applying lubricant to get rid of the creak/squeak. I used my zoom h2n and then removed the ambient noises with adobe audition.
