Paper Fold and Crease

How it's made

Source

one sheet bends, its fibres buckle, then a fingertip slides along the fold to flatten it. Independent pink friction and short filtered white-noise grains model these contacts, without tones.

Body

a thin sheet gives broad, heavily damped bands at 550-2400 Hz; the crease adds 2-6 kHz rasp. Low-Q filtering and a 5-8 kHz ceiling avoid ringing or a brittle high-frequency hiss.

Envelope

soft bend swells during 0-45% of the action; firmer crease contact occupies 40-90%. A small release rustle follows. All layers taper to silence with no room tail.

Events

18-34 irregular fibre slips, each with a 1-3 ms rounded attack and 5-24 ms release; the larger slips accompany bending while finer, denser grains accompany the crease stroke.

Variation

seeded slip times, strengths and band centres vary each take. Thickness lowers the sheet bands and lengthens its buckles; pressure brightens the crease; stroke time changes the whole gesture.

Presets

thin tissue is soft and fine; office paper balanced; card stock coarser with larger buckles; slow crease emphasizes an extended fingertip rub. Close, dry mono leaves space to the scene.
