White Noise Generator

Generate three types of randomized noise directly in your browser using the Web Audio API:

• White noise — equal power across all frequencies (the harsh hiss sound)
• Pink noise — power decreases by 3 dB per octave (warmer, like rain)
• Brown noise — power decreases by 6 dB per octave (deep, like ocean)

Use cases

• Focus and concentration during deep work
• Sleep and relaxation aid
• Sound masking in noisy environments
• Tinnitus relief
• Audio equipment testing
• Baby sleep aid (brown noise)

No download or app required — start the noise instantly.
