How it's made
Source
a dragged item released onto a slot. Contact is a soft 4–8 ms low-passed noise thump (felt pad meeting a surface) followed by a faint, brighter latch tick (under 2 ms) as the item seats.
Body
the slot is a damped panel with one dominant low mode (110–220 Hz, T60 ≈ 60 ms) whose pitch drops about 15 % in the first 30 ms as the contact settles; a second mode near 2.1x adds weight, and a small click mode (1.8–3.6 kHz, T60 ≈ 18 ms) carries the settling click.
Envelope
thump attack ≈ 1.5 ms, 60 dB fall in 60–120 ms; the click lands 12–20 ms after the thump and is much shorter; the whole event is over in about 0.18 s.
Rebound
a softer 1.35x sine re-seats the item about 30 ms after contact, the settling of the drop.
Variation
`rng` mistunes the modes by ±3 % and nudges the click delay, so repeated drops are not identical. Presets change the surface: felt (soft, low), wood tray (firmer, mid) and glass tile (small, bright click).
