About this app

Ambient Sound generates soothing noise in real time — no loops, no audio files, just pure continuous sound designed to help you sleep, focus, or relax.

Choose from three noise types:
• White noise — full-spectrum, bright and consistent
• Pink noise — softer and warmer, the most natural-sounding
• Brown noise — deep, low rumble like a distant thunderstorm

Fine-tune your perfect sound with six controls:
• Volume — up to 200% with smooth soft-clip overdrive for extra presence
• Warmth — low-pass filter that rolls off high frequencies for a darker, cozier tone
• Bass Boost — hardware + software shelf boost for deep, full bass
• Spectral Pitch — shift the tonal character from deep bass to bright high frequencies
• Pitch Shift — transpose the entire sound up or down by up to two octaves
• Modulation — slow LFO that gently breathes the volume for an organic, living feel

Sleep Mode
Tap Sleep Mode to switch to a minimal dark screen with just a clock, a sleep timer (1, 2, 4, or 8 hours), and a stop button. Audio continues playing with the screen on and keeps going all night via a background service — even with the screen off.

Presets
Save your favorite combinations and reload them instantly. Every preset is saved independently, so tweaking and re-saving never overwrites your existing ones. Export all your presets to a JSON file and import them on any device.
