Free · Open · Measured sound
Sound that helps a nervous system settle — and every set ships with the real numbers behind it. Calm you can check, not just take on faith.
You don't have to earn the quiet.
There are more calming tools and techniques out there than ever — almost too many. Some work. Some are supposed to work. Some don't work at all, and it's genuinely hard to tell which is which.
So we set out to build one we could stand behind — through a collaboration we're proud of: musicians, technologists, therapists and mental-health professionals, and the kids who actually live with dysregulation, anxiety and sensory overwhelm.
Baseline is a framework for audio that helps a nervous system settle — grounded, calm, and back in your control. It's built on the qualities we associate with settling — quiet, slow, predictable sound, with nothing that jolts — and every set is measured against exactly that.
Follow the framework to make your own sets and experiences — or use the ones we've already made, and keep making, free for everyone.
For the OTs, teachers, and parents helping autistic and neurodivergent kids settle, ease a hard transition, or come back from overwhelm — a set paired with breathing or deep pressure.
For anyone who needs to come down: after a brutal day, before sleep, in the middle of too much. Caregivers included — you can't pour from empty.
A quiet floor for winding down, resting, or drifting off — at home, in a classroom's calm corner, wherever the volume needs to drop.
Measured, never promised.
We measure; we don't certify. A set “in range” means its sound falls inside a preset someone wrote down — not that it's safe or right for any one child. Watch the kid, not the badge. Their response is the only verdict that counts, and you can't do it wrong.
A growing library you can hear and take, a tool for making your own, the measurements that keep everyone honest, and the practice that ties it together.
Calm, dark, loopable beds — every one measured before it entered the library. Stream them free; join to download and to keep what you make.
Open the player →Pick a pack and a key, let the generator lay out a timeline, shape it by hand, and bake it into a seamless loop — it lands in your library, ready on the board.
Open the studio →Every sound ships with its real measurements against a named preset — startle, darkness, headroom, mono-safety. We measure; we don't certify. See a real report below.

Put on a set. Get comfortable. Try one small thing with your body for five minutes — then notice how you feel. You're the judge, and there's no doing it wrong.
In through the nose, out slowly through pursed lips or a straw — the out-breath longer than the in. For kids: smell the flower, blow out the candle; or bubble-blow through a straw. Try in for 4, out for 6.
Why people use it: a long, slow exhale leans the body toward its rest gear — the parasympathetic side.
A weighted lap pad, a firm hug, palms pressed together, or hands pushing steadily on a wall. Slow and firm — never sudden.
Why people use it: deep-pressure input is a long-standing occupational-therapy strategy for feeling grounded (the evidence is genuinely mixed).
A slow seated stretch, a gentle sway, or a little “heavy work” — carrying something, wall push-ups — as a set lifts back toward alert.
Why people use it: gentle movement and heavy work are common ways to shift arousal; pair with the return of a set.
Helping a child? Your calm is the strongest tool in the room. Breathe slow yourself and let them borrow it. No fixing, no rushing.
Why people use it: children co-regulate with a steady adult before they can self-regulate — this one is well-supported in child development.
Options to try, not prescriptions. Nothing here is guaranteed to work, and the child's own response is the only verdict that counts. Sound is for settling and comfort, not treatment.
We'll be straight with you: the science on "sound that heals" is thin and mixed — which is exactly why Baseline measures what a set is and never promises what it'll do. We'd rather earn your trust than borrow someone else's hype. So here's the honest picture, limitations and all. (Music therapy — interactive, therapist-led — is its own thing; those results don't carry over to recorded sets like ours.)
A controlled study (n=43) found no benefit across the group; response split by individual traits. This is exactly why we watch the listener, not a badge.
Söderlund et al. · Scand. J. Child Adolesc. Psychiatry Psychol. · 2024Earlier positive results didn't replicate — a reminder that a technique working once doesn't mean it works generally.
Schröder et al. · Eur. J. of Special Needs Education · 2025Pooled results for social interaction, behavior, and quality of life sat around p ≈ 0.06–0.09. And it's music therapy, not recorded sets.
Navarro et al. · Frontiers in Integrative Neuroscience · 2025A scoping review maps how music and natural sound affect adult stress: a map of open questions, not a verdict.
Saskovets et al. · JMIR Mental Health · 2025A scoping review of 39 studies calls for stronger work on effectiveness and dosing before anything can be claimed.
Shahrudin et al. · Psychiatry Investigation · 2022A review reframes sound alongside light, space, and materials as sensory-load factors. Useful for how we design; not proof any of it treats anything.
Abdou et al. · Architecture (MDPI) · 2026And what we leave out: "miracle frequency" claims, commercial brainwave products, and tiny or industry-funded studies. If the evidence isn't there, we don't lean on it — that's the whole point. Sound is for settling and comfort, not treatment.
A free account, and a community of people keeping this grounded and honest.
Hear. Feel. Calm.
No two kids settle to the same thing — so Baseline grows from the people using it. You don't need our permission, only the same yardstick everyone else uses: the numbers.
A calm bed along the arc — bowls, a gong, synths, field recordings, whatever settles you. The recording guide covers headroom, the no-startle discipline, and the binaural notes.
Drop it into the on-device analyzer — free with a sign-in, analyzed right in your browser, never uploaded. It reports every property against a named preset and flags anything out of range — that's a hint, not a rejection.
Once it holds up, submit it with its report. The community takes a look, and it joins the shelf — measured, credited to you, openly licensed.
Come back to baseline — anytime you need it.
