Tempered Glass Burst

How it's made

Source

stored stress releases across a safety-glass sheet: a 0.4 ms attack and 28 ms broadband bang. A 4-160 ms branching fracture cloud uses hundreds of short, band-limited micro-impacts per second.

Body

the sheet loses coherence rapidly; 230-2300 Hz flexural modes have only 18-55 ms T60. Small blunt crumbs have widely scattered 1.6-9 kHz modes, T60 12-65 ms, rather than long shard rings.

Events

70-110 primary crumb contacts arrive at 0.06-1.65 s, densely at first then sparsely. Each crumb rebounds twice at shrinking intervals and 0.24-0.46 amplitude; its pitch and pan persist.

Envelope

fracture density and bandwidth collapse over 160 ms; landing energy falls with time. Later grains are softer, with upper modes damped first; a safety fade ends before 2 s.

Layers

centered bang and briefly flexing sheet, wide fracture crackle, dry pebbly contact shower. Rounded 0.3-0.7 ms contact attacks, high-pass DC removal and low-pass filtering avoid stray clicks.

Variation

seeded contact times, crumb dimensions, modal detuning, strengths and stereo positions. Sheet size weights the bang, granulation sets crumb count, floor hardness sets damping and bandwidth.

Presets

compact side pane, dense broad sheet, crisp tile sprinkle, and muted crumbs on rubber.
