Soundie — Your personal sound sanctuary

The Mixer

Every sound, exactly where you want it.

Each layer has its own volume and its own place in the stereo field — fire in your left ear, a creek in your right, thunder far behind. All loudness-normalized so nothing ever jumps out at you.

Per-sound volume & pan

Sculpt the space around you with independent stereo controls for every layer.

Seamless loops

Engineered click-free with sample-accurate looping. You'll never hear the seam.

Living Mix

Volumes drift gently over time, like a real place. Turn it on per sound.

Save & recall

Keep your favorite mixes forever and start them with one tap.

Night Journeys

Your whole night, composed.

A journey is a slow piece of sound dramaturgy: it eases you into sleep with a rich mix, carries you through the night on a minimal bed, and gently brightens before you wake. Pick a template — or compose your own from saved mixes.

Gentle wake-up alarm

Your mix fades down while a soft chime fades in — sunrise for your ears, with a backup notification for peace of mind.

Sleep timer

Prefer silence after you drift off? Set a timer and the mix fades out on its own.

Breathe

The mix breathes with you.

Pick a pattern — Coherent, Box or 4-7-8 — and the whole soundscape swells as you inhale and softens as you exhale. Close your eyes and follow the sound.

Breath sounds

Soft inhale and exhale cues, stretched to match each phase of your pattern.

Voice guidance

A calm voice marks each phase and counts down long holds. Never chatty.

Brainwave

Tuned in real time.

Soundie doesn't play binaural recordings — it synthesizes them live, two pure sine tones with sample-accurate precision. From a 0.5 Hz delta pulse to bright gamma, plus a 432 Hz tuning tone.

Each ear hears a slightly different frequency; your brain perceives the difference as a slow, steady pulse. Use headphones — the effect needs true stereo separation.

Private by design

Nothing about you leaves your phone.

Soundie has no servers, no accounts and no analytics. All 100+ sounds ship inside the app, so everything works in airplane mode — the only network traffic is anonymous purchase validation.

No tracking, no ads

No advertising SDKs, no analytics trackers, no behavioral profiles. Ever.

No account

Open the app and start listening. Your mixes are stored only on your device.

Fully offline

Cabin in the woods, long-haul flight, digital detox — Soundie doesn't care. It all works.
