01 — BUILD YOUR MIX
Pick your layers. Set your levels.
Every sound in the catalog is available as a layer. Add one, ride its fader against the rest, and the address bar keeps up — so the link you copy is always the mix you are hearing.
Ready — pick your layers, then press play.
The link carries your whole recipe — no account, nothing stored on our side.

02 — TUNED STARTING POINTS
Three mixes with the reasoning written down.
The buttons above load these recipes into the mixer. Each one also has its own page explaining what the levels are doing and when the blend stops working.
03 — HOW LAYERING WORKS
Fewer layers, better tuned.
A mix is not a playlist. Two sounds that each work alone will fight if they occupy the same part of the spectrum, and the usual result is a bed that feels busy without masking anything. Start from one steady texture — a noise colour, a fan, a river — and let it carry the level. Everything after that is decoration.
The second layer should cover a range the first one leaves open. Brown noise is almost entirely low end, so rain or a waterfall sits above it without collision; pink noise already reaches into the mid range, so it pairs better with something narrow like a fan than with another broadband source. Keep detail layers well under the bed: at 20 to 30 percent they read as texture, and past 50 they start pulling attention back to themselves, which is the opposite of what a masking bed is for.
Anything with events in it — thunder, birds, a passing train — behaves differently from a continuous texture. Those are the layers that wake people up, so they belong low or not at all in a sleep mix, while they can be exactly right for a background you are meant to notice occasionally. If you are mixing for sleep, the honest test is whether the bed still sounds the same when you stop listening to it.
04 — FAQ
The mixer, answered.
How many sounds can I layer at once?
Up to eight, chosen from all 126 sounds in the catalog. The cap is there because each layer streams its own loop and phones limit how many can decode at the same time — in practice a bed stops getting clearer somewhere around four or five textures.
Do I need an account to save a mix?
No. Your recipe lives in the page URL and in your own browser storage. Copy the mix link and the layers and levels travel with it; nothing about your mix is stored on our side.
Why does each layer loop instead of playing continuously?
Every sound here is a 16-second loop built to wrap without a gap or a click, so it can run indefinitely from a small file. Because the layers start independently they drift apart rather than repeating in lockstep, which is what keeps a long session from developing an audible pulse.
Can I use my mix offline?
Not in the browser — the loops stream, so playback needs a connection. The NoiseTape app stores every sound on the device for flights, trains and rooms with no usable Wi-Fi. Mixing inside the app is planned for a later release; for now the app plays one sound at a time.
Is the mixer free?
Yes, with no signup and no time limit. It is the same free browser playback the rest of the site offers, and the App Store app is a separate 14-day trial with a one-time purchase.
