This is a windchime recorded very quietly struck with a triangle beater with a fairly cheap microphone, noise removed, and normalized to max volume without distortion. Lower note of two.
This recording is a 96khz recording with a contact microphone attached to the steel cable that connects the mast to the deck, in a small whale research boat in the island of dominica.
A delicate metal creaking sound, that could be interpreted as someone sneaking around on creaky floorboards. Useful for building atmosphere in creepy / horror context.
