A good sleep mix is simple. One steady sound, one quieter detail and, if you like, soft music underneath. Here is a recipe you can follow tonight, shown step by step in Berceuse's mixer. The idea works in any sleep sound mixer.
The short answer
Start with one steady sound, like rain or brown noise. Add one detail, like a fireplace, a little quieter. Add soft music under both if you want it. Keep every volume low, then set a timer or let it loop all night, and download the mix so it plays offline.
What makes a good sleep sound mix
A sleep sound mix is a few sounds playing at once, each at its own volume. A sleep sound mixer is the app that lets you build one. You might hear rain on a window, a fire crackling a little further back, and soft piano under both.
A good mix for the night has three qualities:
- It is steady. The sound you hear at 3 a.m. should be the same as the one you heard at 11 p.m. No sudden peaks.
- It is simple. Two or three layers are plenty. More layers often means more things to notice.
- It is quiet. Turn it up only until it softens the sounds you want to hide, like traffic or a snoring partner.
We use Berceuse's mixer as the worked example at every step, because we make it and it puts sounds and music in one place. The recipe itself works in any mixer app.
How to build a sleep sound mix in six steps
- Pick a steady bed sound. This is the base of your mix, the sound that never stops. Good choices are rain, ocean, a river or a noise color like pink or brown noise. Not sure which noise to pick? Our guide to white, pink and brown noise explains how each one sounds. In Berceuse: start a new mix, choose who it is for (you or a baby) and the purpose (sleep, focus or calm for you; sleep or calm for a baby), then pick your bed sound. Rain alone comes in about 20 settings, such as a window, a tent, a roof and a forest.
- Add one detail, a little lower. A detail gives the mix some life. Try a fireplace, distant thunder, crickets or a cat purring. Set it clearly lower than the bed sound, so it sits behind it. One detail is usually enough. In Berceuse: add it as a second layer and pull its slider below the bed sound. You can stack up to 10 layers on iPhone and 6 on Android, but two or three are plenty.
- Add music under it, if you want. Music is optional. If you like it, pick something soft: piano, ambient, harp or slow lo-fi. Keep it at the same level as the bed sound or lower. If you read in bed, choose music without lyrics. In studies, music with lyrics hurt reading more than instrumental music did. In Berceuse: pick a playlist. It plays on its own channel under your sounds, in order or shuffled, with repeat.
- Set each volume. Start with every layer low. Lie down, close your eyes and listen for a minute. If one sound keeps grabbing your attention, lower it. Then set the overall volume as low as still works for you. In Berceuse: every layer has its own slider, so you can lower one sound without touching the rest.
- Choose a timer or all night. If silence wakes you, let the mix loop all night. If you prefer quiet once you are asleep, set a timer. In Berceuse: sounds loop until you stop them. The timer runs 5, 10, 15, 30 or 60 minutes and fades out over the last 30 seconds, so it never stops hard.
- Save the mix and download it. Give it a name you will find in the dark, like "Rain and fire". Then download it, so it keeps playing if the Wi-Fi drops, in the car or on a plane. In Berceuse: pick a cover, save the mix and rename it any time. It waits in your Library tab. With a subscription, download it and it plays offline for up to 30 days between subscription checks.
Sleep sound mixes to try tonight
Here are four simple mixes to start from. Every layer below is in Berceuse's library. Change any layer you do not like.
- Rainy tent. Rain on a tent as the bed. Distant thunder, much lower. No music.
- Fireside. Brown noise as the bed. A fireplace a little lower. Soft piano underneath, at a low level.
- Rainy reading. Rain on a window as the bed. Vinyl crackle, quieter. A lo-fi playlist like Rainy Rhodes under both.
- For a baby. Womb sounds as the bed. Soft shushing, a little lower. Music box lullabies underneath, if your baby likes them.
For a baby, keep it safe. Keep the volume low, keep the phone across the room and never put it in the crib. Children's National Hospital suggests keeping the sound below about 50 dB, "similar to a soft conversation", with the device at least two feet (about 60 cm) from the crib. Our guide on white noise for babies has the full advice.
Common mistakes when mixing sleep sounds
- Too many layers. Five sounds at once can turn into clutter. Start with two and add more if you miss something.
- A detail that is too loud. A fireplace or thunder at full volume pulls you back to listening. Keep details behind the bed sound.
- Volume set in the daytime. A mix that sounds right with the TV on will feel loud in a dark, quiet bedroom. Set the volume in bed, at night.
Does music or sound help you sleep?
Be careful with big promises. A Cochrane review of 13 studies with 1,007 adults with insomnia found that listening to music improved how well people said they slept (moderate certainty). For noise, the Cleveland Clinic points to reviews that found limited evidence that it improves sleep. A mix will not fix a sleep problem. What it can do is give you a steady, familiar sound that you like going to bed with. If you want to dig into music, read does lo-fi help you study or sleep?
Berceuse puts the whole sleep sound mix recipe in one app
Every step above happens in one place in Berceuse. Noise and rain for the bed, a fireplace or crickets for the detail, and a playlist on its own channel underneath. As of September 2026, there are more than 900 sounds and music tracks to choose from.
If you would rather not start from scratch, pick one of 202 ready-made mixes and change a layer or two. For a baby, choose "baby" when you create the mix, then reach for womb sounds, shushing and music box lullabies.
At night, the mix plays with the screen locked, with lock-screen controls on both platforms. On iPhone, say "Play rain on Berceuse" or "Stop Berceuse in 30 minutes" to Siri (iOS 17 or later).

Questions people ask
How many sounds should a sleep mix have?
Two or three is a good place to start: one steady bed sound, one quieter detail and, if you like, music underneath. More layers often add clutter rather than calm.
How loud should a sleep sound mix be?
As low as still works. Turn it up only until it softens the noises you want to hide. For a baby, Children's National Hospital suggests below about 50 dB, with the device at least two feet from the crib.
Should a sleep mix play all night or on a timer?
It depends on you. If you wake when a sound stops, let it loop all night. If you prefer quiet once asleep, use a timer. Berceuse's timer runs 5 to 60 minutes and fades out over the last 30 seconds.
Can I make a sleep sound mix for my baby?
Yes. In Berceuse, choose a baby when you create the mix, then pick from womb sounds, heartbeat, shushing and music box lullabies. Keep the volume low, keep the phone across the room and never put it in the crib.
Do I need Berceuse to build a sleep mix?
No. Any app that lets you layer sounds with separate volumes will work with this recipe. Berceuse makes it easier, with music on its own channel, a baby library and 202 ready-made mixes in one app.
Can I play my sleep mix offline?
In Berceuse, yes, with a subscription. Download a mix and it plays offline. Downloads keep working offline for up to 30 days between subscription checks.
