An extremely squeaky metal bench swing at a public garden. The grating metal begs for lubricant like an old barn hinge. Some background anthrophonics, like a passing truck early and some individual voices during the recording, as one might expect in an urban park.
More walking on metal stairs in a reverberant concrete stairwell. Slower than the first one, with more variety of movement. Recorded with: sanken cs-1e, fostex fr2le.
Me walking on a metal grate in hard soled shoes. Some of the sounds are unpleasant but most are salvageable if you are looking for a casual walking sound.
Very noisy rusty gears on my bicycle, before removing the bike chain for cleaning and oiling. Lots of clicking and mechanical noises. Recorded on a sony px470 dictaphone.
The sound of the bottom of a ceramic mug, dragged over the metal grating of a coffee machine. It sounds like a sword drawn from a scabbard. Recorded using a zoom h6 in the kitchen. Applied a filter to remove unwanted low and very high frequencies. Also corrected the volume level to adjust all four recordings to the exact same level. There are some minor distracting noises - i assume from my shirt while moving the mug over the surface. Also a fan is very faintly audible in the background. If you are interested in a very clean recording of this sound, please let me know.
