A metal ball is one of the cleanest test signals in Foley — it gives you predictable physics with a sharp transient. Roll one across a hard surface and you hear the friction, the slight wobble in trajectory, the bearing-tight resonance of the sphere itself. Drop it and you get a pure impact with a clean tail. That's why puzzle-game designers and Foley artists keep these recordings close: they're the building block for everything from pinball UI to abstract motion design.
Inside the folder you'll find 16 metal ball sound clips — rolling passes on tile and wood, pings on different hard surfaces, drop-and-bounce sequences with decaying tails, and the dry rattle of small bearings in a tin. All free to download, no attribution needed, and the files are recorded with enough headroom to pitch-shift cleanly. Useful in puzzle-game sound design, mechanical Foley layers, ASMR builds, or any motion graphic that needs a believable metal hit underneath.
