156 tracks for sleep

Sound built to be uneventful.

Most sleep audio is made to sound good. Ours is made not to wake you — and every track is measured three ways before it ships. Nothing here is designed to be interesting.

The method

Every track passes three tests, or it doesn't ship.

Not a promise about what sound does to you. A promise about what the file itself is — and one you can check.

Startle

under 12

How sharply the loudest moment rises above everything around it. A sudden jump is what wakes someone who was just drifting off.

Drift

under 8

How much the level wanders across an hour. A track that quietly grows louder brings you up at three in the morning without you knowing why.

Brightness

under 4,000 Hz

How much energy sits in the sharp end of the spectrum. Bright sound is alerting sound, however quiet you set it.

Five spectra side by side: 327 separate sounds down to one

We measured one widely sold sleep track at a startle of 20.1 and a drift of 9.5 — both well over the line, on a product sold for sleep. Nothing in our library passes either threshold.

Don't take our word for it. Use your ears.

The same frequency, three ways. Fifteen seconds each. Don't analyse it — just notice which one you'd want tonight.

Easiest

Music

432 Hz carried inside a slow sustained chord. The gentlest way in.

Middle

Single tone

One note with a few of its natural harmonics. Thinner, warmer.

Barest

Pure tone

One frequency and nothing else. Most people find this hard at first.

It gets simpler on purpose.

On your first nights you can't sleep, so you need something to put between you and the room. By night thirty you don't — and the thing that was helping has quietly become one more thing to pay attention to.

So it's taken away. One layer at a time, slowly enough that no single night feels like a loss. Counted across a full programme, the number of separate sounds in a track falls by more than three hundred.

Nature over noise 327
Brown noise 116
Two crystal bowls 6
One bowl 3
One tone 1

Four programmes, one ladder.

Every one runs in an order. You start at night one and go a night at a time — the sequence has already made the choices for you.

Free Trial

14 tracks · free

Rain, brown noise, two crystal bowls, and eight tracks where a frequency sits inside gentle music. Nothing here is bare — that's deliberate.

Silver

29 tracks · the music one

Eight music tracks with nature over them, six eight-hour nature nights, four bowl sessions, four guided meditations — and a twenty-one night path that thins out as it goes.

Gold

42 nights · no music at all

Six weeks that take a layer away each week. Nature over brown noise, then brown noise alone, then bowls with a voice, then bowls alone, then nine nights of a single tone.

VIP

71 tracks · two programmes

The 45 — forty-five nights, a voice on every one. The 26 — pure and single tone, not a word spoken. They run side by side, and you pick which to be in tonight.
