Sound effects library. Available via A Sound Effect.

MetalMotion is a sound design construction kit that contains four hours of moving metal mayhem: clicks and clanks, rolls and drags, wronks and squeals, scrapes and rattles, ranging from from tiny to monstrous. Nathan Moody’s unique performances with unusual combinations of props produce everything from Foley-like movements to intense groans and howls.

Whether you’re covering a robot’s movements, sweetening weapon Foley, making crafting or pick-up sounds in a game, placing unusual layers beneath a kaiju’s roar, or crushing a submarine with undersea pressure, this collection covers the full range of subtle to raucous. Each file has many performance variations for creative choice and game audio asset creation.

While there are some tasty impacts within, this library’s true focus is on characterful movements: handling, rummaging, opens, closes, ratchets, swirls, rolls, drags, drops, spins, rubs, zuzzes, and bows. Metal containers, filing cabinets, modern appliances, vintage (and very rusty) tools, cymbals, bells, grills, plates, bars, rods, and tubes, and many other props lent their voices to this collection.

This UCS-compliant library was recorded with a combination of standard, contact, and ultrasonic-capable microphones through Millennia preamps. Sample rates vary based on the amount of ultrasonic content in each file. The audio files are mastered for realism, ready for extreme processing and pitch shifting of your own, but still useful in more grounded contexts.
