FAQ

Is my audio uploaded anywhere?

No. Every noise layer is generated locally in your browser using the Web Audio API. Nothing is recorded, uploaded, or sent to a server.

What's the difference between white, brown and pink noise?

White noise has equal energy across all frequencies. Brown noise is deeper and rumbly, with energy falling off faster at high frequencies, while pink noise sits between the two with a softer, more balanced sound.

Can I combine multiple noise types at once?

Yes. Each of the three noise layers has its own on/off toggle and volume slider, so you can blend any combination to taste.
