Cave Drips

How it's made

Source

isolated ceiling drops strike still cave pools, trapping 1.5–6 mm air bubbles (0.5–2.2 kHz). Each rising bubble chirp follows a soft 0.7 ms attack and a 4–12 ms band-limited splash.

Body

a smaller bubble follows 12–28 ms later; the main cavity tone decays naturally through the bubble model. The splash is filtered below 6 kHz so the plink stays rounded rather than metallic.

Envelope

0.22–1.2 drops/s, slowly wandering by ±25 percent; randomized strengths and radii prevent a mechanical rhythm. Voices have a 650 ms safety fade and a 750 ms lifetime.

Space

asymmetric 110–390 ms early wall reflections lose high frequencies on each path; diffuse cave reverberation lasts 1.8–4.8 s. Reverberation is integral to the underground setting.

Variation

seeded event times, bubble sizes, splash lengths, secondary delays and stereo positions. Presets cover a small grotto, a vast chamber, a deep pool and a more active bright seep.
