What changes when you install Foyer?
This page plays one fixed brown noise loop. It is enough if you only want a sound in a browser tab. The app is for building a mix you can return to, without needing to keep this page open.
Layer sounds. Add rain or fireplace sounds over brown noise. The free tier supports three sounds at once.
Place each sound. Drag it closer to raise its volume, or left and right to change its direction. Try headphones to hear the placement.
Save your mix. Keep up to five rooms in the free tier. Return to the arrangement without rebuilding it.
Listen offline. The app includes the sounds. Core playback needs no internet connection. Buying or restoring an unlock still needs the App Store.
Make a simple brown-noise room
Start with brown noise at a low, comfortable level. Add rain on one side and a fireplace on the other. Move each sound until the balance suits you, then save the room. All three layers fit in the free tier.
On Mac, control your room from the menu bar while you work. On iPhone, keep the sound going with the screen locked. Prefer a browser-only tool with frequency sliders? See our myNoise comparison. For other native options, compare ambient sound apps for Mac.
What brown noise is
Brown noise puts more energy into low frequencies than white noise, giving it a deeper, rumbling character. Which sound you prefer is personal. Use the preview to decide whether this particular loop belongs in your mix.
About this loop
A 90-second brown noise loop from the Foyer library, repeated without a seam. It is a fixed loop rather than a live generator with adjustable bands; if you want per-band control, myNoise’s generators are the better tool. In the app you can layer it under rain or a fire and push it to the edge of the room, where it holds the floor without drawing attention.
Questions
What is the difference between brown, pink and white noise?
How the energy is spread. White noise is flat across all frequencies and sounds like hiss. Pink noise tilts toward the low end and sounds like even rainfall. Brown noise tilts further still and sounds like a distant rumble. Deeper generally reads as softer; which one helps you is personal.
Is Foyer a free brown noise app?
Yes. The free tier includes the full sound library, up to three simultaneous sounds and five saved rooms. A $9.99 one-time unlock adds unlimited sounds and rooms plus other features. One purchase covers Mac and iPhone. There is no subscription or account. See what is included.
Does brown noise work offline in the app?
Yes. All sounds are bundled with Foyer, so core playback works offline. Buying or restoring the optional unlock needs an App Store connection. This browser preview needs a connection to load its audio file.
Can I combine brown noise with other sounds?
On this page, no, it plays alone. In the Foyer app you can put brown noise far away as a floor and place rain, fire or ocean around you on top of it. Each sound keeps its own position and volume, and the room remembers the layout.
