Cave ambience for D&D
A cave is one quiet air loop and resonant drips every four seconds. The dial-by-dial recipe, and the environment ready to play.
A cave is two sounds, not twenty: a quiet air loop underneath at half volume, and water landing on stone every four seconds with a medium room behind it. Keep the drips irregular — a metronome reads as a leaky tap, not a cavern. The chains and the cave-in ship switched off, and that is the right place for them.
What it sounds like
The thing that makes a cave sound like a cave is not the drip. It is the gap between the drips, and what the room does to each one on the way back. A real cave is almost silent — a low wash of moving air with no direction to it — and then a single drop lands and you hear the size of the place in the tail of it.
Which is why this one runs so sparse. Four seconds between drips looks wrong written down and sounds right in the room: after about a minute the table stops hearing it as a sound effect and starts hearing it as the place they are standing in. The air loop is the floor of the mix, not a feature. If anyone can describe it to you afterwards, it was too loud.
It is also the only one of these fifteen that ships with half its layers switched off, which is deliberate. An empty cave and an occupied one are the same recipe with two checkboxes between them.
The recipe, dial by dial
This is the environment as it ships. Every layer is the same kind of thing — one sound from the library and a set of dials — so there is nothing special about which slot a sound sits in. The names are only names.
| Layer | Sound | How often | Wander | Volume | Distance | Reverb | Echo |
|---|---|---|---|---|---|---|---|
| Rhythm | Cave drips (resonant) | every ~4.0 s | 60% | 70% | close | medium | 2 bounces |
| Ambient | Cave wind (quiet) | loop | — | 50% | close | off | off |
| Accent (off) | Chains rattling | every ~20 s | 70% | 30% | far | large | 2 bounces |
| Extras (off) | Cave-in | every ~40 s | 80% | 30% | very far | large | 2 bounces |
Master volume 80%. Every number above is read out of the environment that ships in the app, and printed in the words the app prints beside each slider.
- Rhythm — Four seconds, wandering 60%, is the line between a cave and a dripping tap. The echo is doing the work the frequency is not — one drop with a medium room and two bounces behind it covers more space than four dry ones.
Cave drips (resonant) - Ambient — Half volume, which is quieter than it looks on the slider. The air loop exists to stop the drips happening in a void.
Cave wind (quiet) - Accent — Off, and pushed far when you turn it on. This is the switch for “something is chained up down here”.
Chains rattling - Extras — Off, very far, one every forty seconds. This is the layer for the ten minutes after somebody fails a Stealth check.
Cave-in
What each dial does is covered once, properly, in Environments & layers.
Boards to load with it
The environment is the place; boards are the things that happen in it. These three ship built in and suit this one:
Load them, then press + New scene and the environment and the boards come back together next week in one tap. Scenes covers that.
Make it yours
A wet cave
Swap the ambient loop to Wet grotto and pull the drip interval in to about two seconds. It stops being a dry stone passage and becomes somewhere water is still working on.
A cave with something in it
Turn Extras on and leave it very far. One distant collapse a minute does more to a table than any monster sound you can tap.
A cave that is still filling
Add a layer on Waterfall (distant) at about 30% and push it far. There is now water you cannot see, somewhere off to the left.
None of this is destructive: the built-in environments cannot be overwritten. Change what you like, and press Save a copy as… when it sounds right.
The recordings
Every sound this environment uses, and who recorded it. Most of the library is public domain; the Creative Commons Attribution recordings are credited here because that is what the licence asks for. The full list is on Sounds & licensing.
