Castle Dungeon

How it's made

Source

three independent sources inside a large stone vault. A wall torch burns (turbulent gas roar plus flame flutter), loose chain links shift somewhere far away, and groundwater drips from the ceiling.

Torch

a soft roar (brown noise at 65–340 Hz) and a pink-noise band around 900 Hz whose level is flickered by fast random drift (4–12 targets/s) and a slow breath (≈ 0.3 Hz); sparse, high-passed crackle ticks.

Chains

now and then a cluster of 2–5 clinks 30–140 ms apart. Each is a 1 ms noise burst into steel-bar modes (inharmonic, 0.16–0.7 s) at 1.1–5 kHz, low-passed and level-reduced so it reads as far away.

Drips

a falling drop traps a bubble (Minnaert ring, 2–5 mm, 0.7–1.6 kHz, rising chirp) plus damped stone modes at 620–2100 Hz on a wet stone floor, with a tiny splash tick; drops arrive irregularly at 0.1–0.6 per second.

Space

the vault is part of the sound. Chains and drips feed a cave reverb with a long, dark decay (2.8–5 s, with 47/83 ms early reflections); the cold, stony tone comes from damping the highs of that tail, not from the dry sources.

Variation

`rng` varies every drip radius, clink pitch, cluster size, timing and pan; presets change the mix between torch, chains, drips and the size of the room.

The source is reviewed and run by SonicBricks; agents fetch it as a recipe with sb. It is not published on this page.
