How to add ambient sound to a D&D game
How loud a bed should sit, how many layers is too many, what the Distance readout words mean, and when to cut the sound dead instead of playing something.
Play one looping bed for the place — cave wind, rain, a tavern crowd — quiet enough that nobody raises their voice over it. Add one or two random layers for the things that happen now and then, and push anything meant to be elsewhere back with the Distance dial. Keep one-off effects on boards, and know where STOP is.
Start with one sound, not ten
The commonest mistake is a wall of noise. Begin with a single looping bed that matches the place — cave wind, rain, a tavern crowd — at a volume where a player can still talk across the table without raising their voice. If anyone asks you to turn it down, it was already too loud.
Add the occasional sound that makes it alive
A loop alone flattens out after a minute because your ear stops hearing it. What keeps a place alive is the thing that happens now and then: a drip, a distant door, a crow. In Thaumaturgy those are random layers, fired on a cadence with a randomness dial so they never fall into a pattern. Two is usually plenty.
Push the background further back
Anything that is supposed to be elsewhere — a crowd downstairs, fighting in the next street — wants the Distance dial up. Distance makes a sound quieter, duller and wider at once, which is what your ear actually uses to judge how far away something is. It is the single most useful dial in the app.
Keep effects separate from ambience
Ambience runs by itself; effects are things you press. Keep them on boards — big labeled buttons for a sword, a door, a scream — so that in the moment you are hitting one button, not hunting a filename.
Save the scene before the session, not during
Set up the places you expect to visit ahead of time and save each as a scene: a scene is an environment plus the boards loaded with it, stored together. At the table you are then one tap from the whole thing instead of building anything live. With an account you can group a night's scenes into an adventure, and keep each game in its own campaign.
Know how to stop everything
Have one control that kills all sound instantly and know where it is without looking. STOP ALL is in the top bar, Esc does the same on a keyboard, and on a phone Stop is the last segment of the bar along the bottom. Someone will take a phone call, or a scene will turn serious, and fumbling for the volume is worse than silence.
How loud should it be?
Quieter than you think. Ambience is working when players stop noticing it and start describing the room back to you. A useful test: read a sentence of boxed text aloud at your normal voice. If you find yourself projecting over the sound, it is too loud.
How many layers is too many?
An environment takes up to twelve layers, and most sound best with fewer than eight. Past about eight the mix turns muddy. If a place sounds busy, the fix is almost always to take a layer's volume or distance down rather than to add another one.
What does the Distance readout mean?
Every dial prints a word beside it rather than a number, so you can set it without doing arithmetic. Distance reads:
| Readout | Where it puts the sound | Use it for |
|---|---|---|
| close | In the room, at the party's feet | The bed, and anything they are standing in |
| nearby | The same space, a few paces off | Accents that belong to this room |
| far | Down the hall, through a wall | The thing they can hear but not see |
| very far | Another part of the building entirely | Trouble arriving later |
Reverb reads the same way — off, tight, medium, large, cathedral — and loops start dry on purpose: a recording of a cave already has the cave in it. It is the short random clips that need reverb to sit in the same space as the bed.
When should I play nothing at all?
Silence is a tool. Cutting the sound dead the moment something goes wrong is more dramatic than any sting you could play, and a quiet table makes the next scene's ambience land harder. Do not feel you have to fill every minute.
