MoonQuist: Baby Sleep Noise

Drown out distractions with beautifully layered noise. 7 handcrafted presets for sleep, focus, and calm — or mix your own. No ads, no subscriptions, no internet required.

MoonQuist generates rich, layered ambient noise in real time — right on your device. Blend four distinct noise types, choose from handcrafted presets, and let the sound evolve naturally with built-in modulation. No recordings on loop. No ads. No account required.

FOUR NOISE TYPES, ENDLESS COMBINATIONS

• White Noise — Full-spectrum static for masking sharp sounds
• Pink Noise — Deeper, balanced noise favored for sleep studies
• Brown Noise — Low, rumbly warmth like distant thunder
• Green Noise — Mid-frequency texture reminiscent of rustling leaves

Mix all four at any ratio, or start with one of the built-in presets.

7 HANDCRAFTED PRESETS

• Stormy Sea — Crashing and rolling low-end with white-noise spray
• Deep Sleep — A heavy pink-and-brown blanket with no high frequencies
• Forest Rain — All four layers with gentle modulation throughout
• Ocean Waves — Deep swells with a touch of shimmer
• Focus Mode — Steady, even coverage with no movement — pure concentration
• Velvet Abyss — Dark, enveloping brown noise with a hint of pink
• Static Bloom — Bright and textured, led by green and white noise

Every preset is carefully tuned so you can tap and go.

LIVING SOUND

MoonQuist isn't a static loop. Each noise channel can have independent volume modulation — a slow, 45-second breathing rhythm that makes the sound feel alive and organic. A dynamic low-pass filter adds subtle tonal movement over 60-second cycles. The result is ambient noise that stays interesting without becoming distracting.

GENTLE FADE-IN

Don't want sound to hit you all at once? Use the fade-in button to start from silence and smoothly ramp up to your chosen volume over 30 seconds — perfect for easing into sleep or a focus session.

BACKGROUND PLAYBACK & LOCK SCREEN CONTROLS

MoonQuist keeps playing when you lock your phone or switch apps. Control playback directly from the Lock Screen and Control Center — just like a podcast or music player.

FULLY CUSTOMIZABLE

• Adjust each noise channel independently
• Set a master volume
