Free Online Noise Generator
Generate pure white, pink, and brown noise for audio testing, studio calibration, or deep focus. 100% free and runs locally in your browser.
Why use a noise generator?
Generating pure noise is an incredibly useful tool for sound design and acoustic testing. White noise, which contains equal energy at all frequencies, is commonly used to mask distracting sounds, helping people focus or fall asleep.
For music producers, pink noise is even more important. Because pink noise sounds equally loud across the entire human hearing spectrum, producers use it as a reference tool to balance the volume levels of their drum kits and synthesizers.
How to generate noise
Select the color of the noise you want to create. White noise sounds very bright and hissy, like television static. Pink noise sounds slightly deeper, like heavy rainfall. Brown noise focuses heavily on the low end and sounds like a deep, rumbling waterfall.
You can set the exact duration you want and hit generate. We will instantly synthesize the audio and give you a high quality WAV file to download for your projects or sleep playlists.
Frequently Asked Questions
What is Brown noise good for?
Brown noise has a very steep roll-off in the high frequencies, meaning it is almost entirely low, soothing bass. It is incredibly popular for treating tinnitus or masking deep rumbling sounds like traffic.
Why do producers use Pink noise?
Pink noise mimics how the human ear naturally hears volume. Producers use it as a mixing reference. If every instrument in a song can just barely be heard over a layer of pink noise, the mix is usually perfectly balanced.
Will this hurt my speakers?
Pure white noise played at maximum volume can definitely damage cheap tweeters because it contains so much high-frequency energy. Always start with your volume very low before hitting generate.
