White, Pink & Brown Noise Generator
Noise Generator
Play white, pink or brown noise straight from your browser. Use it for focus and sleep, masking distractions, testing speakers or calibrating a room.
White, pink and brown noise
White noise has equal energy per frequency and sounds bright. Pink noise rolls off the highs for a balanced sound and is the standard for speaker and room calibration. Brown noise rolls off even more for a deep, rumbly tone many people find relaxing.
How to use it
Pick a type, set the volume and press Play. You can download a 10-second WAV to loop in any player or DAW.
