Real bowls. Real air. No loop you can hear.

Most sleep sound is thirty seconds long.

That is the quiet truth of the category. A short clip, a synth pad standing in for a bowl, and a loop flag, because a loop flag is free and a composition is not. So the same little swell comes back around every minute, your ear learns it by minute four, and by minute ten you are listening to the seam instead of the sound. Then a number gets printed on the artwork to make it feel like medicine.

We went the other way. Nothing here is generated, nothing repeats inside a listening session, and there is no number on the artwork. What there is instead is a room, some real instruments, and about a year of arranging them.

What you are hearing

Everything on this shelf was in a room.

Tibetan singing bowls, a church bell, crystal bowls, temple bells, a low drone, a circle of human voices humming, and the air of the rooms they were recorded in. We tuned them, measured them, and wove them so that pieces breathe together instead of clashing.

The slow waving you will hear when two bowls overlap is not an effect. It is what two real bowls, almost in tune, do to the air.

Two other decisions you will only notice by their absence. Every piece sits at the same loudness, matched to a track already shipping in the app, so nothing on the shelf jumps at you in the dark. And the same piece plays the same way every time, with no shuffled variants. At 3 AM, familiar is the point, and a surprise is a defect.

We wrote an audio engine so a bowl could ring true at 3 AM.

An Endless piece is one continuous composition of twelve to thirteen minutes, written so its ending flows back into its own beginning. Getting that join to be inaudible turned out to be the hardest thing in the whole shelf.

Neither a web audio element nor Web Audio could do it. One survives a locked screen but cannot wrap without leaving a hole, the other wraps perfectly but gets shut down the moment the phone locks. So we wrote a native engine for it, chained on the platform's own audio graph. Then we found the real culprit: every one of these files decodes with about 25 milliseconds of the codec's own padding sitting at the head, which is enough to drop the level audibly at every single wrap. We measured it, at 1105 frames, and skipped past it. The join now moves less than the sound naturally moves from one moment to the next.

The Toning drone goes further. It is built from about nine layers of humming and bowl tone, each rising and falling on its own cycle length, and those lengths were chosen to share no common factor with each other. The practical effect is that the combination does not come back around inside anything you would call a listening session. Two earlier versions of that piece were thrown out for failing exactly that test by ear.

One of them is free, and always will be.

After the Wave is fifteen minutes for the hour after a panic attack, when you are wrung out and lying down is the whole plan. It is not a sample and it is not a trial. It is the same promise the panic button already makes, extended to the hour that follows it, and it will never move behind a paywall.
