Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
This white noise generator synthesises noise in real time with the Web Audio API, so there are no audio files to download and nothing is uploaded. Choose white noise for an even spread across frequencies, pink noise for a softer and warmer sound, or brown noise for a deeper low-end rumble, then set a comfortable volume and press play. The noise loops seamlessly for as long as you like, which makes it useful for concentration, masking background sound, unwinding, or falling asleep. Keep the volume moderate, especially with headphones.
Short answers for the questions people usually have before trying a utility like this.
White noise is even across all frequencies, pink noise rolls off the highs for a softer feel, and brown noise emphasises the low frequencies for a deeper, rumbling sound.
No. The noise is generated live in your browser using the Web Audio API, so nothing is downloaded to play and nothing is ever uploaded.
Yes. The noise loops continuously until you press stop, so you can run it in the background for as long as you need.
