Match Pop

How it's made

Source

a short cluster of small air bubbles popping at a wet surface, one pop per matched tile. Each ring is the Minnaert resonance of a 1.2–3 mm bubble (f₀ ≈ 3.26 / r, ≈ 1.1–2.7 kHz), so smaller bubbles sit higher.

Body

every pop is the physical `bubble` model (damped sine with an upward chirp as the bubble shrinks) plus a quiet octave-up partial for brightness. The radii shrink pop by pop, so the cluster climbs a little in pitch.

Transient

each burst starts with a 1–2 ms high-passed noise tick under a soft attack, which keeps the onset crisp without a click. The last pop is slightly louder and carries a short airy sparkle tail.

Envelope

pops are spaced 45–100 ms apart with a small timing jitter; each rings for ~60–90 ms and the whole cluster ends near 0.4 s through an explicit closing envelope.

Variation

`rng` detunes each radius by ±4 % and jitters the spacing; `pops` sets the count, `climb` the upward step between pops, `size` the overall pitch, `sparkle` the bright tail.
