Glass Shatter

How it's made

Source

glass hitting a hard floor: a 1 ms contact and a 90 ms cluster of brittle fractures. Band-limited noise bursts overlap irregularly; a damped 170-420 Hz floor impulse adds weight.

Body

the intact vessel briefly flexes at 650-1600 Hz, then loses coherence as it fragments. Each shard has flexural modes at 1 : 1.91 : 3.37 : 5.23, with independent 2% mistuning.

Shards

14-36 fragments strike at 0.03-1.4 s. Each bounces 2-4 times; flight intervals shrink by 0.48-0.68 and impact amplitudes by 0.36-0.58, while its modal pitch and pan stay consistent.

Envelope

contacts rise in 0.3-0.8 ms; shard modes decay 60 dB in 70-390 ms, upper modes first. The fracture spectrum darkens from 10 kHz to 4 kHz; late impacts are sparse and softer.

Variation

seeded timing, fragment size, strength, pan and modal tuning; size sets pitch and weight, hardness sets contact bandwidth, scatter sets flight time, and ring sets floor damping.

Presets

tile tumbler, delicate stemware, heavy bottle on wood, and a dense sheet-glass crash. All are dry; a smooth safety fade follows the naturally decaying final fragments.
