Sleep sound mixer
Blend browser-generated rain-like noise, soft noise and a low tone for a personal soundscape.
A QUICK WALKTHROUGH
How to use this tool
- Set the levels of the three layers.
- Set each layer and the master level from 0–20%. Changes apply the next time you press Play.
- Press Play to synthesize audio locally; press Stop when finished.
Browser-generated audio
The mixer uses Web Audio to generate a looping noise buffer, filtered rain-like noise and a 174 Hz tone. It does not download or stream recordings.
Bounded controls
Each layer and the master level are set within 0–20%. These are gain controls, not measurements or guarantees of sound pressure or sleep benefit. During playback, sliders change the next playback settings only.
GOOD TO KNOW
Common questions
Is this a medical sleep aid?
No. It is a simple sound tool and does not diagnose or treat sleep problems.
Does it use recordings?
No. Sound is generated locally after you press Play.
Why is there no sound?
Your browser may require a click to start audio, Web Audio may be unavailable, or all levels may be zero.
