Rain Synth: Sleep Sounds

Free with no ads. RainSynth helps you to fall asleep with realtime soundscapes and white noise. Shape the sound by dragging the glowing cursor across the pad, or let dynamic motion take you through an ever-changing ambience.

Six synthesisers. One gesture. • RainSynth — layered rainfall with variable intensity and texture • ForestSynth — filtered natural noise with woodland character • FireSynth — crackling warmth from soft embers to a roaring blaze • OceanSynth — coastal soundscape from distant shore to crashing surf • BreathSynth — guided breathing with a slow, resonant rhythm from subtle background to deep practice • NoiseSynth — sculpted noise across the full spectrum, from warm brown rumble to white noise to crisp violet air

Features: • 100% free. No ads. No in-app purchases • Real-time audio synthesis — every sound is generated live, never repeated • XY pad control — drag to shape intensity and texture simultaneously • Dynamic mode — hands-free slow wander through the soundscape • Sleep timer — auto fade-out from 30 minutes to 4 hours • Reactive visuals — the interface responds to every drop, crackle, and wave in real time • Three preset positions per synth for quick access • Dark minimal UI designed for nighttime use
