Everything the ember does

Ember Noise is small on purpose: one mixer, a handful of deep tools, and no feature that needs a login. Here is the whole of it.

The blend matrix

Four sounds sit at the corners of a square; the glowing ember sits wherever you drag it. Corner volumes follow the ember's position bybilinear interpolation — continuous weighting on both axes — so the mix shifts as smoothly as your finger moves. Center is an even four-way blend; a corner is a solo; the space between is the point.

All four streams stay loaded while the app plays. Dragging changes only their weights, which is why the blend answers instantly.

Ember Noise on iPad: a dark four-quadrant mixer with White Noise, Fire, Rain, and Pink Noise in the corners and a glowing amber ember blended toward Fire.

Ten sounds in the box, yours by import

Three generated noises — White, Pink, Brown — synthesized from scratch so they loop perfectly, plus seven voiced ambient loops: Rain, Train, Crickets, Ocean, Wind, Fire, and Rings of Neptune.

Bring your own audio too: Import from Files accepts any Apple-decodable file and streams long recordings, with loop shaping and a seam preview so hour-long imports loop cleanly.

The sound picker on iPad: ten built-in sounds including generated White, Pink, and Brown Noise and looped Rain, Train, Crickets, Ocean, Wind, Fire, and Rings of Neptune, plus Import from Files.

A real EQ on every sound

Each sound carries its own three-band parametric EQ — low shelf, mid bell, high shelf, each with frequency, gain, and Q. Drag the nodes on the live response curve, solo-preview the sound you're shaping, and A/B against bypass. Too-bright white noise becomes a soft hush without touching the rest of the blend.

The per-sound EQ →

Presets, automation, stop timers

A preset captures the whole mix — ember position, corner sounds, and every EQ curve — and recalls it in a tap. Automation drifts the ember on its own over a duration you choose, and stop timers wind the audio down after you're asleep, with your favorite durations saved as one-tap presets of their own.

Presets & automation →

The preset menu on iPad with a saved preset named fireside, options to create, save, and save-as, and Send to Device for direct transfer to a paired device.

Send to Device — no cloud in the middle

Built a perfect sleep mix on your iPad? Send it to your Mac or iPhone directly, over your own network: Bonjour discovery, paired identities held in the Keychain, andend-to-end encryption (authenticated HPKE). The preset travels with its imported sounds, and the sender only reports success after the receiver has verified and durably saved it. Nothing touches a server, because there isn't one.

How Send to Device works →

The Send to Device sheet: a preset named drift into sleep ready to send to a paired Living Room Mac over the local network, with a note that the encrypted preset goes directly to the paired device and nothing is uploaded to a cloud service.

A Mac app that lives in the menu bar

On the Mac, Ember Noise is a native AppKit/SwiftUI app showing the landscape mixer in a resizable window. Close the window and the sound keeps going — play/pause, volume, presets, and stop-timer status stay one click away in the menu bar, with opt-in Launch at Login. Media keys and Now Playing work the way Mac apps should.

Ember Noise on Mac →

The Ember Noise menu-bar popover on Mac: play and volume controls, a saved preset named first light, Open Mixer, and Launch at Login and Show in Dock switches.
