In Donut’s acoustic lab, we are equipped with state-of-the-art sound analysis instruments.
We can precisely deconstruct and reconstruct any sound wave frequency, and generate the theoretically most “perfect” white noise: uniform, smooth, like a flawless sheet of pure white light.
But it was too “white.” White to the point of monotony, white to the point of lifelessness.
Algorithmically synthesized nature always misses a breath—missing the ripple of a sudden breeze across the water, the faint cry of a distant bird, or that unexpected little moment that stirs the heart.
We realized: it was time to step outside.
True “field recording” isn’t downloading from a sound library. It’s walking across the world with our feet, listening with our ears and heart, and capturing the Earth’s very breath.
First Stop: Arashiyama Bamboo Grove, Kyoto — Capturing the Shape of the Wind
Challenge:
Wind itself is silent. We had to find the softest, most whisper-like sound as it passes through a medium.
Voice Notes:
In Kyoto’s bamboo forest, wind takes on a form and a voice.
Bamboo leaves brush against each other, creating a dry, rustling crispness—dense yet gentle.
We tuned our microphones not to capture the grandeur of the whole forest, but to trace the passage of a single breeze—from its sweep over the canopy to its fading deep within the grove.
This became the heart of our “Bamboo Breeze” mode. It isn’t an endless loop of noise, but a living, breathing sound narrative with a beginning, middle, and end.
Second Stop: Iceland’s Black Sand Beach — Recording the Frequency of Solitude
Challenge:
We want the purest, most powerful waves—not the cheerful surf of holiday beaches, but something grand, solemn, and calming.
Voice Notes:
Our Part-time Music Collaboration Team camped for three days on Iceland’s black sand coast.
The waves here are unlike anywhere else—the surf drags black stones as it crashes and recedes, producing a low, gritty roar, like the Earth itself sighing.
We recorded that voice. It is unlike any synthetic white noise—you can hear every grain of sand grinding and colliding within the tide.
That raw, “imperfect” texture is exactly what we wanted: a frequency of solitude that makes one feel small, and therefore, at peace.
Third Stop: A Nordic Forest Cabin — Collecting the Sample of Silence
Challenge:
True silence is not the absence of sound, but the amplification of life’s tiniest rhythms.
Voice Notes:
Outside a wooden cabin deep in a Nordic forest, Part-time Music Collaboration Team recorded “silence.”
It was a peculiar experience: hold your breath, and the microphone unveils an unseen world—the soft plop of snow sliding off a branch meters away, the faint scuttle of an insect beneath moss, even the delicate resonance of your own heartbeat.
We learned that sleep is aided not just by sound, but by the sense of safety carried in those gentle traces of life.
This recording didn’t become a direct playback mode, but it gave us the golden standard for what a sleep sound should be: a safe auditory cocoon.
From Field Recording to Co-Creation: Your Sounds, Too, Are Part of the World
These journeys gifted us precious soundscapes, but also a realization: the world is full of countless fleeting moments worth capturing.
LUUNE’s footsteps are finite—but our users’ ears and hearts are infinite.
This is what inspired us to create the World Sound Diary feature in the LUUNE App: a global, ever-growing sound map, built together with you.
Record Your Moments:
Whether it’s the crack of a glacier in Alaska, dawn birdsong in Yunnan’s rainforest, or simply children’s laughter in your neighborhood park—you can easily record and upload it.
Define Your Wake-Up:
Set your own recordings as wake-up sounds. Imagine being woken on Monday by a Swiss mountain stream, and on Wednesday by the campfire crackle from last weekend’s trip—seamlessly carrying that relaxation into your workday mornings.
It’s not just an alarm. It’s a gentle sound-journey across memories.
Co-Create a Planet of Sounds:
(With permission) these fragments collected by users worldwide will become LUUNE’s living sound library.
One day, you might even receive a “sound blind box” at bedtime—randomly hearing someone else’s serene moment from the other side of the world.
Let the Machines Handle Precision, and the Humans Handle Emotion
Science can tell us which frequencies promote sleep.
But only life can tell us which sounds touch the soul.
Donut’s acoustic system is the precise “machine” of the lab—but the soul within it flows from wilderness, forest, ocean, and every user’s lived moment.
We provide the framework. Together with you, we shape its living heart.
So next time you find yourself in a place that brings you peace or joy, open the LUUNE App and record it.
Every capture you make contributes a unique fragment to the LUUNE Planet—a gentle, shared world of sound.
The world is vast. Together, we can softly place it inside Donut.
