Stone Plunk

How it's made

Source

a stone parts the water with a 3 ms rounded pressure onset and a 20-65 ms filtered splash.

Body

the entrained 10-23 mm air cavity closes 28-62 ms later; its 140-326 Hz bubble chirps upward. A weaker 1.73-ratio damped pressure mode adds a hollow, non-musical pop, not a ringing solid stone.

Layers

a low 90-175 Hz displacement thump precedes the cavity; 2-5 small return droplets follow at 150-490 ms, over a falling 2.8 kHz to 650 Hz turbulence band. No room reverb is added.

Envelope

splash attack 2 ms, cavity attack 2 ms, pressure decay 120-210 ms; water settles by 0.76-0.94 s with a final smooth fade. Higher-frequency spray dies before the low cavity.

Variation

seeded cavity tuning +/-3%, droplet times/radii and stereo positions vary naturally. Size sets cavity pitch and collapse time; splash sets spray; settle sets return-water duration.

Presets

small pebble is high and brisk; deep stone is bass-heavy; round plunk isolates the cavity; splashy toss has stronger, wider return spray. All are single entries into deep water.
