Bottle Crate Rattle

How it's made

Source

bottles collide in four walking-driven clusters, each with 4-12 contacts over 160 ms. A 0.3 ms attack and 1.5-3 ms filtered noise pulse excite each glass shell, with softer rebounds.

Body

six bottles retain distinct pitches around 760-1500 Hz, scaled by bottle size. Shell modes have ratios 1, 1.51, 2.37, 3.83 and 5.14; upper modes decay faster than the lowest (70-330 ms T60).

Layers

glass ringing and quiet contact ticks sit above damped crate modes at 175, 410 and 730 Hz. Brief filtered friction accompanies each weight transfer; there is no continuous noise or reverb.

Envelope

four irregular 320-440 ms carrying cycles end with weaker settling contacts. A final 80 ms fade follows the natural glass decay; the default gesture lasts about two seconds.

Variation

seeded timing, impact strength, strike colour and narrow stereo positions vary per contact. Activity controls cluster density and hardness; load damps and darkens glass; size lowers its modes.

Presets

careful carrying is sparse, hurried carrying is dense, full bottles are damped and heavy, and empty bottles ring brighter with less crate weight.
