Colored noise for sleep, relaxation, and focus

Different noise colors distribute sound energy across frequencies in different ways. This gives each one a distinct character:

• Brown noise has a deep, low-frequency sound.
• Pink noise has a balanced, softer character.
• White noise spreads energy evenly across frequencies.
• Blue noise emphasizes higher frequencies.
• Purple noise has an even brighter high-frequency character.

Lullwave also includes mixes of noise waves and noise pulses, making it easy to find a background sound that suits your environment.

Ambient and nature sound library

Alongside colored noise, the app offers a range of continuous ambient sounds:

• Flowing water streams
• Rain sounds
• Sea waves
• Water droplets
• Boiling water
• Train sounds
• Fireplace sounds

These sounds can provide a consistent audio backdrop for winding down, reading, working, or masking distracting environmental noise.

A simple sound app without an account

Lullwave focuses on quick access to its sound library. You do not need to create an account, register, or manage a subscription before choosing a noise or ambient sound.
