A short rip through paper: a rough band of noise that keeps bursting instead of hissing, opening up in pitch as it goes, with a dry landing at the end. Use it for tearing a page, opening an envelope, ripping a receipt, or any small irreversible action.
tear: white noise 300 ms, band-pass with the centre sweeping 2000 Hz -> 4600 Hz (Q 0.8), level rising from 0.25 to 0.55, falling away over the last 70 ms — and multiplied by a gain that jumps to a new random value (0.3-1.0) every 2-4 ms, so the band stutters instead of humming fibres: about 150 grains of 1-3 ms across 50-300 ms (not just the first 90 ms), same level as the body, high-passed at 3.6 kHz — each one is a fibre snapping land: white noise 40 ms, low-pass 500 Hz, 0.12 level, starting at 250 ms (the sheet coming free) no echo; buffer 0.40 s
