Distant Metal Clang

How it's made

Source

one heavy steel object striking another; a 2 ms attack and 16 ms filtered noise contact, with a 95 ms low structural thump. No exposed broadband click reaches the listener.

Body

flexural modes at ratios 1, 1.47, 2.09, 2.81, 3.76, 5.13, 6.94 and 9.27 above 105-230 Hz; paired modes split by 0.6-2 Hz beat gently. Low modes have 2.4 s T60, upper modes die sooner.

Envelope

immediate softened impact; metal settles into its low modes, then a diffuse room tail. A final smooth fade from 4.25 to 4.9 s guarantees silence without chopping the initial ring.

Space

direct sound is narrow and subdued; wall returns at 73-231 ms spread across the stereo field. A wet hall with 2.8-4 s decay supplies dense late reflections; air and wall losses darken the tail.

Variation

named random streams vary contact noise, modal tuning by 0.6 percent and reflection timing. Size controls mass, distance controls occlusion and direct balance, room controls reflection spread.

Presets

loading hall, low basement girder, brighter high gallery, and almost hidden far-wing impact.
