How to use
- Press Play. The preset starts rain with a random-mode thunder layer behind it.
- If thunder feels too frequent, open the Thunder layer and raise Min delay to 15–20s or drop Probability to 0.4.
- For deeper sleep masking, add Brown Noise at 20–30% in the full mixer.
- Turn on the 30m or 60m sleep timer for a smooth fade-out.
FAQ
Why thunder in random mode?
Looped thunder sounds artificial — your ear learns the pattern in a few minutes. Random mode fires thunder at unpredictable intervals with an optional probability gate, which is how real distant storms behave.
Is thunder at bedtime disturbing?
Distant, low-volume thunder tends to act as a mask rather than a wake-up cue, similar to how people report sleeping well through real storms. If it still wakes you, lower the thunder layer volume below 30% and raise Min delay.

What you can shape with this engine
- Noise generation — white, pink, and brown noise beds for masking
- Nature and ambience — rain, ocean, forest, fire, thunder, wind, and more
- Layered playback — loop steady beds, fire events on an interval, or rare sounds on random delays for realism
- Presets and sharing — Quick Presets, sleep timer with fade-out, and Share links that restore a mix
Common use cases
- Focus and relaxation — steady masking that hides unpredictable noise
- Sleep — a stable audio floor so small sounds are less likely to wake you
- Learning and experimentation — hear how different layers and levels behave over time
This page opens the mixer with a goal-specific preset. For a blank canvas, start from the main Sound Generator hub.
How this preset is built
Two layers with very different jobs:
- Rain (loop, ~60%) — the steady masking bed. Your brain files it as
ambient weather and stops tracking it. - Thunder (random, ~35%) — low-volume distant rumbles that fire at
unpredictable intervals (5–20s default) with a 70% probability gate.
The result is weather that feels alive, not a track on repeat.
Tuning for your room
- Bedrooms with outside noise benefit from louder rain; suburbs and quiet
rooms do fine at ~50%. - If you're a light sleeper, reduce Thunder Probability to 0.3 or 0.4. It
will read as an occasional rumble rather than active weather.
