The Sound Studio
Mix your own calming soundscape from twelve original, generated sounds — rain, ocean, wind, noise, drones and more. Start with a preset, then make it yours. Nothing is pre-recorded; every sound is created live in your browser.
General information, not medical advice. Talk to a doctor about any health concern. Keep the volume low, especially for long sessions or sleep. For all-night listening, set the sleep timer.

About the Sound Studio
The Sound Studio is our in-house instrument for calm — a generative soundscape engine that builds relaxing sound in real time, right in your browser. Nothing here is a recording: each layer is generated live in your browser from synthesized noise and tones, and Auto-evolve can slowly drift the mix so it doesn't feel static. Mix as many or as few layers as you like, lean on a preset, or build something entirely your own.
The twelve layers
The engine is organized into three families. Noise covers the classic colors of noise — white, pink, and brown — steady sounds many people use to mask distraction and settle for sleep, though the evidence that they improve sleep is weak. Nature recreates the textures we instinctively find calming: rain, ocean swell, wind, a flowing stream, and occasional birdsong, the soundscapes we explore in nature sounds for relaxation. Tonal adds musical warmth: a slow ambient drone pad, a deep sub hum, gentle chimes, and an optional binaural layer.
Presets, mapped to the moment
Not sure where to start? Each preset is tuned for a purpose and linked to the guide that explains the evidence behind it — Deep Sleep, Focus, Deep Calm, Meditation, and more. They're starting points, not rules: the best soundscape is the one you find calming, so adjust freely.
Auto settings
Three helpers do the thinking for you. The sleep timer fades the sound out gently and stops it, so nothing plays all night (a 2026 sleep-lab study found all-night pink noise reduced REM sleep). More in the best music for sleep. Auto-evolve slowly drifts the mix so long sessions stay alive rather than static. And the breathing pacer gives you a calm visual to slow your breath — slow breathing and calming music both have good evidence for helping you relax, as explained in music for stress relief.
An honest note
We built this to be genuinely useful, not magical. Any calming effect of generated sound most plausibly comes from masking distraction and supporting slow breathing — not from secret frequencies. The binaural layer in particular is included for those who enjoy it, but the science behind brainwave "entrainment" is mixed; read our evidence-first take before relying on it. As always, this is for relaxation and general wellbeing, not medical treatment.
Frequently asked questions
Is the Sound Studio free?
Yes — it runs entirely in your browser, free, with no account and no downloads. All sounds are generated live in your browser; no recordings are used.
Why does nothing play until I press start?
Most browsers block sound until you tap or click on the page. Press the play button once and the soundscape begins; after that you can mix freely.
Can I use it for sleep?
Yes. Many people find steady sound helps them settle, though the evidence that noise improves sleep is limited. Use the Deep Sleep preset and set the sleep timer so the sound fades out gently after you drift off, rather than playing all night.
