White Noise Sleep Sound Mixer

Layer 48 ambient sounds — rain, thunder, birdsong, ocean waves, white noise, and lo-fi — into your ideal mix with per-sound volume control. Drift turns your iPhone into a personal ambient sound mixer for sleep, focus, meditation, and relaxation. ▸ 48 SOUNDS, UNLIMITED COMBINATIONS Browse sounds across six categories — Nature, Instrumental, Ambient, Noise, Meditation, and Urban. Tap any sound to activate it. Adjust individual volume sliders to balance rain against birdsong or tune the white-noise bed under a lo-fi melody. ▸ BINAURAL-INSPIRED TRACKS Alpha Waves and Theta Waves are included as meditation sound layers, ready to mix with rain, noise, nature, or instrumental tracks. ▸ 22 CURATED PRESETS Twenty-two presets — Thunderstorm, Sleep, Deep Focus+, Tropical Paradise, Zen Garden, City at Night, and more — each with pre-tuned sound combinations and volumes. Tap once to start. ▸ SLEEP TIMER Choose from six timer durations — a short session up to a two-hour wind-down. Drift stops the active mix when the timer finishes. ▸ SAVE YOUR SOUNDSCAPES Create and save your own custom mixes as named soundscapes. Recall them any time with a single tap. ▸ SESSION MEMORY Close the app and relaunch — your active sounds, volumes, master volume, and selected preset persist automatically. Your mix is waiting when you return. Whether it is rain on a quiet evening, waves at sunrise, or a thunderstorm that helps you think — build the atmosphere that fits your moment. One-time purchase. No subscription. Requires iOS 16.0 or later.
