Is this tool free?+
Yes. The noise generator is completely free. Play ambient noise for as long as you need.
Do I need to sign up?+
No. Pick a noise type, adjust the volume, and hit play. No account required.
Is my data private?+
Noise is generated algorithmically in your browser using the Web Audio API. No audio is recorded, and no data is sent to any server.
What noise types are available?+
White noise (equal energy across all frequencies), pink noise (deeper, more balanced), and brown noise (heavy low-frequency rumble). An auto-stop timer from 0 to 120 minutes lets you set it and forget it.
