This sounds like an old mississauga transit (mi-way) bus engine starting, running for a short time, then slowing down. The sound was made by simply playing the sound of air raid siren backwards.
A spooky sounding organ. Made into a loop by taking the sample andpasting the reverse at the end; not too obvious. Clip from the movie"carnival of souls" which is in public domain. Cruddy quality source.
An upright piano chord sequence repeated three times, and a clock ticks!. This recording is not a perfect loop but able to be made such. Tempo is synced to clock ticks and so is almost accurately 120 bpm. Recorded by sony xperia c5305.
This is a casio sk-1 i did around a year ago or so from reeds book plus a video out and 18 on board rca jacks with another 25 pin dpi that can run through a breakbox. Noise and bent sounds as usual. Crashes alot. Oh and it's not the hardest "mother of bends" serious, i wore socks and everything. : ).
While we were in studio, a friend of mine found out that his drum throne creaks in a cool way. He gave it a little performance, and i got it on "tape". Recorded with a zoom h2 at 96khz/24-bit. Uncut, unprocessed, raw.
This is an old 70's phone, i pick up the receiver, dial a few times and ring off afterwards. Recorded on 44,1 24-bits with a shure ksm27 large-membrane condensor mic.
Sound shutter and rapid shooting of old nikon 2020 camera edited with audacity. Recorded on shock-mounted zoom h1 mic, record level 62, autogain off, gain low. Record location, inside a car in a single garage (great sound room).
